Description

[0001] Manufacturing plant and method for producing a ski edge

[0002] The invention relates to a manufacturing system for producing a ski edge, as well as a method for producing a ski edge. Furthermore, the invention comprises a computer-implemented method for providing parameters for producing a ski edge, as well as a system comprising a manufacturing system and a digital processing unit for producing a ski edge.

[0003] A method for producing a ski edge profile is known, for example, from EP0601024 B1, in which the ski edge is formed from tempered steel, which has a head comprising the running surface and a flank projecting into the body of the ski, and the following method steps are carried out successively: a) rolling or drawing an edge profile; b) tempering the entire edge profile by heating to a hardening temperature and subsequent tempering; c) partially heating a flank to a temperature greater than the tempering temperature with simultaneous cooling of the head;d) punching of recesses and openings in the flank, whereby during the tempering of the entire edge profile the deviation in its Rockwell hardness over the cross-section and the length of the edge profile is set to less than 2 degrees HRC, at a constant heating temperature and heating time and whereby the edge profile is subjected to a constant bending deformation after partial heating and before punching, in which the flank is stretched by a constant amount;

[0004] A method for producing a shaped ski edge, in which the ski edge continues around a ski tip, is known, for example, from DE3510545 A1, in which a straight, profiled edge strip corresponding in length to the entire edge length is bent into a substantially U-shape in the region of its center by means of bending tools, so that the outer edge web is then provided with separating slots running transversely to the longitudinal direction of the edge in the side edge regions, whereupon the ski edge in the region of the ski tip and / or the ski end, in which the edge web is not interrupted by separating slots, is adapted to the final ski shovel or ski end shape by means of bending tools, wherein bending of the ski edge according to the ski shovel shape is preferably omitted for the time being.

[0005] A disadvantage of state-of-the-art manufacturing processes is that they are often carried out in different production facilities and process steps, with individual steps also being carried out manually, and thus the quality of the edge geometry often does not have optimal curvature with regard to its outer contours.

[0006] The object of the present invention was to overcome the disadvantages of the prior art and to provide a manufacturing plant and a method for producing a ski edge by means of which a user is able to provide an improved quality of the ski edge.

[0007] This task is solved by a manufacturing plant and a method for producing a ski edge.

[0008] The production plant according to the invention for producing a ski edge comprises

[0009] - a control device;

[0010] - an unwinding device for providing a ski edge blank;

[0011] - a feed device for transporting the ski edge blank along a transport direction;

[0012] - a cutting device for cutting the provided ski edge blank to a predetermined length with respect to a longitudinal extent;

[0013] - a deformation device, wherein the ski edge blank can be deformed transversely to the transport direction by means of the deformation device.

[0014] By means of a production system according to the invention, the ski edge blank can be provided from a storage facility and bent into a ski edge along its longitudinal extent by means of a feed movement of the feed device and a deformation movement of the deformation device, without the latter having to be temporarily stored at another facility or processed by hand, so that the most uniform shaping of the ski edge can be achieved.

[0015] Preferably, the entire curvature of a ski edge to be produced can be produced by the production system (particularly preferably in a single pass with respect to the feed movement), so that after cutting to length and forming by the production system, a ski edge is produced that is finished with respect to its curvatures to be bent. This allows the steps required for forming to be kept as short as possible, thus improving the quality of the ski edge. The production system preferably has a transport plane that runs parallel to the transport direction and extends in a horizontal direction.

[0016] The feed device preferably comprises a drive unit which drives the feed device for conveying the ski edge blank and thus specifies the movement speed along the transport direction or transport plane and can be changed by this.

[0017] The production plant can preferably comprise a marking device which is designed to mark a reference point of the predetermined length along the longitudinal extent on the ski edge blank (at least virtually), wherein the reference point is aligned with respect to the longitudinal extent at a center of an opening or at a center of a web of the ski edge blank. In this regard, the ski edge blank is preferably optically inspected with respect to the transport direction or the transport plane, so that at least one opening and / or a web at a distance with respect to the predetermined length is selected and the web or opening which is closest in terms of the distance is measured, so that its geometric center along the longitudinal extent is marked using the reference point. The marking device can also mark the marking purely virtually orin the control system, so that the reference point is not visually recognizable, but is monitored along its length by a detection unit or the like (e.g., an optical sensor), so that the respective position along the ski edge blank is known via the control system. Furthermore, the reference point can be mechanically incorporated or removably applied, e.g., with a color coating, e.g., with a varnish or the like.

[0018] This center can preferably be used for at least one curve to be formed, since the material properties are uniform starting from the center in a respective direction along the longitudinal extent, whereby a curve aligned therewith can also be produced more uniformly. Furthermore, an asymmetrical curve can also be provided, so that a specific offset of the curve relative to the reference point is provided.

[0019] Based on the reference point, improved ski edge cutting can also be achieved. For example, if a predetermined length of the ski edge is used for cutting, this can be shifted with respect to a starting area and an end area during ski edge production if, for example, the actual curvature differs from a theoretical curvature, and thus a starting area and an end area are also corrected with respect to this difference.

[0020] According to a preferred embodiment, the manufacturing plant comprises a punching device for producing punched-out portions along the longitudinal extent of the ski edge blank, preferably arranged between the unwinding device and the deformation device.

[0021] According to a possible embodiment, it can further be provided that the punching device in a ski edge blank is used to produce at least some of the openings and webs only in the production plant.

[0022] According to a particularly preferred embodiment, the feed device comprises circumferential clamping elements (along the transport direction), wherein the ski edge blank can be clamped transversely to the transport direction by means of the clamping elements and can be moved along the transport direction (together with the clamping elements during clamping). Such a configuration enables particularly precise guidance or feed movement of the ski edge blank along the transport direction, whereby the associated deformation by the deformation device can also be made more precise, thus improving the quality of the curves to be produced. The clamping direction of the clamping elements is preferably perpendicular to the transport plane.

[0023] The clamping elements can preferably be designed such that they follow the ski edge blank in sections (with respect to a distance along the transport direction) during clamping, preferably linearly. In particular, a circular path of the clamping elements can be formed along the transport direction, with the clamping elements being returned counter to the transport direction, preferably along a part of the circular path that is located in a region away from the ski edge blank.

[0024] The clamping by the clamping elements can be unilateral, so that the clamping elements are provided only on one side of the ski edge blank, and on at least one opposite side, the blank is merely guided and held against the clamping. However, oppositely arranged clamping elements can preferably be provided, which clamp the ski edge blank from at least two opposite sides.

[0025] The deformation device can preferably comprise a bending tool that is adjustable in a bending plane perpendicular to the transport direction. Preferably, at least one first and second adjustment axis are provided, by means of which the bending tool can be adjusted along two axes, preferably arranged perpendicular to each other (in the bending plane), for deforming the ski edge blank.

[0026] According to an advantageous embodiment, the bending tool can comprise at least two bending dies arranged perpendicular to one another, wherein the ski edge blank can be received between the bending dies along its longitudinal extent so that the ski edge blank rests against the two bending dies. The bending dies can each be adjustable with respect to the aforementioned adjustment axes, wherein the two bending dies are particularly preferably adjustable with respect to one another with respect to a respective adjustment axis so that the two bending dies are stationary with respect to one another. Preferably, each bending die has a curved surface, in particular with a constant radius, which is intended to rest against a planar surface of the ski edge blank.

[0027] According to a further development, the bending tool can comprise a rotating body mounted relative to a rotational axis, wherein the first and second bending shapes are formed by two bending surfaces that are conical relative to the rotational axis. The conical bending surfaces are preferably tapered toward one another, particularly preferably each inclined at 45° to the rotational axis.

[0028] Preferably, it can further be provided that the deformation device comprises a pivoting arrangement, wherein the bending tool can be pivoted about a pivot axis by means of the pivoting arrangement. Particularly preferably, the pivot axis is parallel to the transport direction and perpendicular to the bending plane. By means of a pivot axis, it is possible, on the one hand, to adjust the bending tool into different orientations with regard to its contact with the ski edge blank for the latter's deformation movements. Furthermore, it is also possible, however, to rotate the ski edge blank in the transport direction during the deformation so that it experiences a twist about an axis in its longitudinal extent, for example in order to twist it before a possible torsion arises due to the deformation, in order to counteract a plastic deformation by the bending tool with regard to the torsion, or to cancel this out or compensate for it.

[0029] Furthermore, it can be provided that the pivot axis is movable, for example, that the pivot assembly can be calibrated accordingly, so that the pivot axis can be adapted to different ski edge blanks. For example, a center of gravity of the ski edge blank can be taken into account, and the bending stiffness, or rather a shear center of the ski edge blank, can be determined with respect to its bending stiffness and a bending moment, relative to which the pivot axis can be adjusted.

[0030] Particularly preferably, the cutting device can also be pivotable about the pivot axis in order to cut the ski edge blank to length perpendicularly or orthogonally to its planar surfaces.

[0031] Furthermore, it can be provided that the deformation device comprises a guide device, wherein the ski edge blank can be stabilized by means of the guide device against its deformation transversely to the transport direction. Particularly preferably, the guide device is designed to be rigid with respect to adjusting movements (along the adjusting axes) of the deformation device or of the bending tool for deforming the ski edge blank. The guide device can also be designed to be pivotable about the pivot axis, particularly preferably pivotable by means of the pivot arrangement. Thus, the guide device can be pivoted separately with respect to the bending tool, but preferably together with the bending tool. Furthermore preferably, the guide device has elements that move or rotate along in the transport direction and are stationary with respect to the feed (along the transport direction).

[0032] The term "stabilizable" means that the ski edge blank is held in the area of ​​the guide device by the guide device, counter to the deformation movements transverse to the transport direction induced by the deformation device, so that it does not deform in another area along its longitudinal extent (before the section to be deformed) and thus preferably extends / runs relative to the transport direction until it is guided in the guide device. Furthermore, the guide device can prevent the ski edge blank from deflecting in the transport direction directly in front of the bending tool, counter to the deformation direction.In a further development, the guide device can comprise at least two guide elements arranged opposite one another along the transport direction with respect to the ski edge blank, wherein each guide element has at least two guide surfaces designed to engage at least two planar surfaces of the ski edge blank. Particularly preferably, the two guide elements are each designed to engage two opposing planar surfaces, so that the two guide surfaces can each enclose a rectangular cross-sectional profile.

[0033] Particularly preferably, the guide elements can also be designed in the form of rotational bodies with axes (and rotatable in the transport direction). The two guide surfaces of a respective guide element are preferably arranged perpendicular to each other, so that the guide elements can rest against two adjacent surfaces or planar surfaces of a ski edge blank.

[0034] Furthermore, the two guide elements can preferably be designed to be adjustable with respect to an axis, so that their distance from one another (with respect to the cross-section of the ski edge blank to be accommodated between them) is adjustable. The axes can preferably be arranged perpendicular to one another. Furthermore, by adjusting them along the axes, a contact pressure can also be generated against the ski edge blank. Preferably, the contact pressure can be selected such that the guide elements do not deform the ski edge blank with respect to its flexural rigidity, but are at least constantly pressed against it in order to compensate for tolerances of different heights and widths along the longitudinal extent.

[0035] Furthermore, the guide elements can have conical guide surfaces with respect to their respective guide axes, which are inclined relative to one another. Furthermore, the axes of the guide elements can be arranged at an angle to a transport plane of the production system, in particular at 45°. The conical guide surfaces can also be inclined relative to this axis, depending on the inclination of the axis relative to the transport plane, so that they are aligned parallel or perpendicular to the transport plane.

[0036] Furthermore, the production plant can comprise a testing device which is designed to detect at least one of the following properties of the ski edge blank - with regard to its longitudinal extent at least locally in the region of the testing device;

[0037] - a hardness of the ski edge blank (e.g. Rockwell);

[0038] - a geometric cross-section of the ski edge blank; - a surface roughness of the ski edge blank;

[0039] - a temperature of the ski edge blank.

[0040] - a longitudinal profile of the ski edge blank (parallel to the transport direction).

[0041] Furthermore, the parameters recorded by the testing device can be used to correct the cross-section and its properties of the ski edge blank.

[0042] The method according to the invention for producing a ski edge comprises the steps of:- providing a previously mentioned production plant according to the invention

[0043] - Providing the ski edge blank from the winding device;

[0044] - Conveying the ski edge blank along the transport direction by means of the feed device;

[0045] - Cutting the ski edge blank to length using the cutting device;

[0046] - Deforming the ski edge blank transversely to the transport direction by means of the deformation device, wherein a curvature of the ski edge blank is produced by a movement of the ski edge blank along the transport direction by means of the feed device and an adjusting movement of the deformation device transversely to the transport direction.

[0047] Preferably, it can be provided that the ski edge blank is bent with respect to its predetermined catches in a central section with respect to its longitudinal extent, so that it has two legs arranged next to one another with respect to the transport direction, thus enabling a circumferential ski edge profile. Preferably, the ski edge blank can be bent in the central section such that the two legs are inclined towards one another (thus bent more than 180°), so that in a stress-free (unguided) state they cross or touch at a point along the longitudinal extent. This can be provided, for example, so that the legs are guided apart by means of elastic deformation during later use of the ski edge in a ski and can be mounted in this state.

[0048] A preferred embodiment provides that the ski edge blank is guided along the transport direction by means of the feed device through the deformation device, and the ski edge blank is cut to the predetermined length (only) after its deformation by means of the cutting device, preferably perpendicular to a planar surface of the ski edge blank. The method can further include a previously mentioned marking device; wherein, preferably by means of a detection unit (preferably associated with the marking device), at least one opening and at least one web in a central section or a predetermined longitudinal section with respect to the predetermined length are detected, and the reference point along the longitudinal extent of the ski edge blank is marked at least virtually with respect to a center of the opening or a center of the web. As already mentioned, the marking or the reference point can be set (only) virtually, e.g.in the control device. With respect to a purely virtual marking, the marking device can also be a virtual device, e.g., forming part of the control device.

[0049] Particularly preferably, it can be provided that the deformation of the ski edge blank is referenced using the reference point. Preferably, a respective processing step (at least) by the deformation device can be aligned with the reference point with respect to the longitudinal extent of the ski edge blank, so that, for example, a curve to be produced is referenced to it or is aligned according to a respective distance, starting from the reference point. Furthermore, multiple reference points can also be provided for multiple curves.

[0050] Furthermore, it can preferably be provided that the bending tool of the deformation device is adjusted during the deformation process of the ski edge blank in a bending plane arranged perpendicular to the transport direction, preferably with respect to at least two adjustment axes, such that the ski edge blank is bent out of the transport plane in one direction and is reshaped into the transport plane by means of a further adjustment movement of the bending tool in the opposite direction. For example, the ski edge blank can be deformed at least in one direction perpendicular or oblique to the transport plane (upward) and reshaped in the opposite direction by pivoting the bending tool, preferably together with the guide device, about the pivot axis.Preferably, a curvature can thus be formed with respect to the transport plane, which curve lies outside the transport plane with respect to at least one curved section, and particularly preferably runs back into the transport plane in two directions (along the longitudinal extent). Furthermore, it can preferably be provided that the ski edge blank is rotated, in particular elastically and / or plastically rotated, about the pivot axis by means of a pivoting movement by means of the guide device for its deformation. This can primarily counteract unwanted torsion of the ski edge blank, but also enable an improved transfer of the ski edge blank into the bending tool, which in turn results in improved curvatures.

[0051] Furthermore, the invention comprises a computer-implemented method for providing parameters for the production of a ski edge.

[0052] The computer-implemented method comprises the steps;

[0053] - Providing a digital computing unit;

[0054] - Execution of a computer program product for processing and managing ski edge data using the digital processing unit

[0055] - Providing a virtual ski edge;

[0056] - Parameterizing the virtual ski edge to derive ski edge blank parameters,

[0057] - Providing the ski edge blank parameters to a production plant for producing a ski edge from a ski edge blank.

[0058] By means of a computer-implemented method, additional ski edge values ​​can be provided for a previously described production plant or a method for producing a ski edge in order to provide the production plant with new ski edge geometries or to be able to continuously improve or update its processing settings.

[0059] The ski edge data can include all possible data required to produce the ski edges, including data from virtual ski models, metadata, data from different processing devices in the manufacturing plant, as well as data regarding different raw materials to be used, as well as required energy, etc.

[0060] The step comprising parameterizing the virtual ski edge can preferably include derivation in the form of reverse engineering, in which the virtual ski edge is at least partially converted into a ski blank. For example, the virtual ski edge can be available as a CAD model and, based on the ski edge data present in the computer program product, can be converted into a ski edge blank to be used (for the ski edge). In this regard, a fully formed ski edge can be transferred into the ski blank, e.g., in the form of undeformed blank material, in order to obtain the information relevant for the processing and production of the ski edge for the production plant.

[0061] This is particularly advantageous because skis often require a finished ski geometry based on their use, and therefore a ski edge geometry based on the ski geometry must also be used.

[0062] The ski edge blank parameters can preferably be geometric parameters that are formed along its longitudinal extent, such as curvatures, cross-sections, material, etc.

[0063] Preferably, the ski edge blank parameters may comprise at least one of the following parameters;

[0064] - a (predetermined or precalculated) total length of the ski edge blank (to be formed) with respect to its longitudinal extent (with respect to the ski edge to be produced;

[0065] - a position of a curvature of the ski edge blank to be formed with respect to its longitudinal extension;

[0066] - at least one radius of curvature for deformation of the ski edge blank;

[0067] - an orientation of a curvature to be formed in spatial coordinates;

[0068] - a position and a length of a central section with respect to the longitudinal extent of the ski edge blank for the production of a ski tip;

[0069] - a cross-sectional profile of a ski edge blank;

[0070] - a center of gravity and / or a center of shear with respect to a ski edge blank geometry;

[0071] - a reference point, preferably for a curvature, in particular a previously described reference point along a longitudinal extension of a ski along the longitudinal extension of the ski edge blank with respect to a center of an opening or a center of a web

[0072] - a measurement for a cross-section of the ski edge blank with regard to post-processing steps after its processing by the production line (e.g. edge grinding)

[0073] Furthermore, for example, the control device of a previously mentioned production plant can be set up to machine a ski edge blank based on the provided ski edge blank parameters (and in this regard, if necessary, to independently create the adjustment movements of the individual processing devices of the production plant),

[0074] Preferably, the computer-implemented method may further comprise the following steps:

[0075] - Creating machining parameters using the ski edge blank parameters;

[0076] - Creating a machining program for the production plant to machine a ski edge blank using the machining parameters.

[0077] The machining parameters can preferably include at least the positioning movements of the deformation device and the feed movements of the feed device. Furthermore, the machining parameters can include control variables of all devices and units of the production facility. When creating the machining parameters or the machining program, for example, different tool types and dimensions of the devices of the production facility (as well as the interactions of several of them with each other) can be taken into account, which are used to form the ski edge blank parameters. For example, the machining program can include the (or different) feed rates and the dependent positioning movements of the deformation device.

[0078] Furthermore, the creation of the machining parameters may thus include importing tool data from the database of the computer program product.

[0079] The computer-implemented method may preferably comprise providing a display and input device that is connected or connectable to the digital processing unit; wherein the display and input device is configured to transmit at least one of the following parameters to the digital processing unit:

[0080] - Ski edge blank parameters;

[0081] - Processing parameters for a manufacturing plant.

[0082] The display and input device can comprise a control panel of the production system, or an external computing system that can be connected to the digital computing unit, e.g., a mobile device, a smartphone, a tablet PC, or the like. Furthermore, the computer-implemented method can comprise the following steps:

[0083] - Recording of real deformation parameters of a ski edge blank with regard to its processing in a production plant;

[0084] - Recording of real machining parameters of the production plant depending on the recorded real deformation parameters of the ski edge blank;

[0085] - Providing the recorded real deformation parameters as well as the real processing parameters to the digital processing unit;

[0086] - Updating the computer program product with respect to the recorded real deformation parameters as well as the real machining parameters.

[0087] The recorded deformation parameters can include, for example, curvatures, inclinations of the ski edge blank with respect to its deformed areas and the real processing parameters, the associated positioning movements of the deformation device and / or feed movements of the feed device, as well as punchings in dependence on movements of the punching device, etc., as well as data of the tool geometry(s) used.

[0088] Furthermore, the provision of a virtual ski model can take place in the computer program product, wherein the virtual ski edge is derived from a geometry of the virtual ski model.

[0089] In a further embodiment, the computer-implemented method may comprise the following steps:

[0090] - transmitting an external model, comprising an external virtual ski model or an external virtual ski edge, to the digital processing unit;

[0091] - Comparing the external model with the ski edge data of the computer program product by the digital processing unit;

[0092] - Providing feedback based on the comparison performed, wherein the feedback comprises at least one of the following;

[0093] - information as to whether ski edge blank parameters can be created based on the external virtual model;

[0094] - an error message if no ski edge blank parameters can be created based on at least one area of ​​the external model, whereby the area is marked in a virtual image of the external model; - a change suggestion for at least one area of ​​the external model if no ski edge blank parameters can be created based on the area.

[0095] - a prompt for changed parameters relating to at least one area of ​​the external model.

[0096] Preferably, the computer-implemented method comprises the provision of a digital twin of the production plant (or a virtual production plant) with the ski edge blank and the ski edge to be produced.

[0097] Furthermore, communication with an external system can be provided.

[0098] The computer-implemented method may further comprise the steps:

[0099] - Obtaining external parameters of an external system for at least one ski edge to be produced,

[0100] - Processing the external parameters based on the stored ski edge data and providing at least one of the following parameters to the external system;

[0101] - a quantity of a required raw material of the production plant for producing at least one ski edge

[0102] - a duration of a manufacturing process for at least one ski edge by the manufacturing plant

[0103] - the required energy and / or consumption (e.g. kWh, CO2) of the production plant for producing the ski edge.

[0104] Furthermore, a computer program product according to the invention can be provided which, when executed by a computing unit, carries out the method steps.

[0105] Preferably, the computer program may include the database for managing ski edge data.

[0106] Furthermore, the computer program can create a virtual production facility for producing a virtual ski edge by using the ski edge data stored in the database; wherein the computer program product is connected or connectable to at least one real production facility for producing a ski edge, and the database can be continuously updated based on real parameters of the real production facility. Thus, a computer program product according to the invention can also be integrated into a production facility or software for resource planning and consumption.

[0107] It should be noted that the computer program product can be stored on a computer-readable storage medium or data carrier which can be read by a computing unit.

[0108] Furthermore, the object mentioned at the outset is achieved by a system which comprises a production plant according to the invention, as well as a digital computing unit which is connected to the production plant and is set up to carry out the computer-implemented method, wherein the system is further designed to carry out the method according to the invention for producing a ski edge.

[0130] By way of introduction, it should be noted that in the variously described embodiments, identical parts are provided with identical reference symbols or component designations. The disclosures contained throughout the description can be applied analogously to identical parts with identical reference symbols or component designations. Furthermore, the positional information chosen in the description, such as top, bottom, side, etc., refers to the directly described and illustrated figure, and these positional information must be applied analogously to the new position in the event of a change in position.

[0131] In Fig. 1, a production plant 1 according to the invention for producing a ski edge is shown roughly schematically.

[0132] The production plant comprises a control device 3, which is generally intended for plant control and preferably comprises a computer program product configured to provide virtual ski edge models. The computer program product can also be executed on an external digital processing unit, via which the control device is connected, or can be accessed in the form of a web application. Furthermore, the production plant 1 can preferably comprise at least one input and display device 22, which is connected to the control device 3. Via an input and display device, for example, all plant controls of the production plant 1 can be reproduced, but also additional inputs can be made by an operator of the production plant 1, or the computer program product can be operated.

[0133] The manufacturing plant can comprise different processing devices, process a ski edge blank within the manufacturing plant, preferably supported by the computer program product, whereby different possible processing devices are explained below and are generally described and illustrated in the figures.

[0134] For producing the ski edge, the production system 1 comprises an unwinding device 4 for providing a ski edge blank 5; this unwinding device can preferably be designed in the form of a drum or the like, from which the ski edge blank 5 can be unwound or provided in the form of a continuous material. It should be noted at this point that other designs of a storage container or the like for providing the ski edge blank 5 can also be provided.

[0135] Furthermore, the production plant 1 comprises at least one feed device 6 for conveying the ski edge blank 5 along a transport direction 7. The feed device 6 is preferably connected via the control device 3 to the other units of the production plant 1 in such a way that their speed can be adjusted for moving the ski edge blank 5 along the transport direction 7.

[0136] Furthermore, a cutting device 8 is provided for cutting the provided ski edge blank 5 to a predetermined length 10 with respect to a longitudinal extent 9. The predetermined length 10 can be specified by the system control in the form of an absolute value. Furthermore, this can be specified or determined by the computer program product and, for example, derived from a geometry of a virtual ski edge. Furthermore, a deformation device 11 is provided, wherein the ski edge blank 5 can be deformed by means of the deformation device 11 transversely to the transport direction 7, so that it can be deformed, bent, and preferably twisted, for example, within a specific radius of curvature relative to the transport direction.

[0137] Preferably, a feed rate of the feed device 6 along the transport direction 7 can be coupled to a deformation movement (or speed) of the deformation device 11 (transverse to the transport direction), so that the combination of the movements defines a radius of curvature as well as an arc length (with respect to the longitudinal extension 9) of the ski edge blank 5, wherein these parameters for controlling the feed device and the deformation device are preferably provided or selected from a deformation table of the computer program product.

[0138] Furthermore, the production plant 1 can comprise a marking device 12 which is configured to mark a reference point of the predetermined length 10 along the longitudinal extension 9 on the ski edge blank 5, wherein the reference point 13 is aligned with respect to the longitudinal extension 9, preferably at a center of an opening 14 or at a center of a web 15 of the ski edge blank 5; which reference point 13 is indicated in Fig. 3. The reference point can preferably be created virtually, so that it is only provided in the computer program product and can be monitored, for example, by means of a detection unit of the marking device.In particular, the reference point 13 can be used to minimize tolerance deviations, since, for example, the openings and webs of a ski edge blank used may not have exactly the same dimensions over the entire length and thus a calculated length position with respect to the longitudinal extension (e.g. for a curvature) may deviate from a real ideal position in this regard.

[0139] In this regard, the marking device 12 can comprise a detection unit E (not shown in detail), which detects the nearest web 15 and the nearest opening 14 in the central section or in a predetermined longitudinal section with respect to the predetermined length and, based on a criterion, preferably parallel to the transport direction, determines the geometric center of the web or the geometric center of the opening and marks the reference point 13 along a line perpendicular to the transport direction at a height of the determined center by means of the marking device. The reference point can also be mechanically incorporated or be in the form of a colored marking, a machine-readable feature, or the like. In particular, in the case of a colored marking, an applyable color can be used, e.g., a varnish, which color can be easily applied to the ski edge blank during its advance, e.g.,with a nozzle or a laser head. As already mentioned, the marking can also be done virtually.

[0140] Furthermore, Figs. 1 and 2 indicate a possible punching device 16 for producing cutouts along the longitudinal extension 9 of the ski edge blank 5. The cutouts are preferably provided for correcting the ski edge blank 5 in the region of the curvatures to be produced, so that, for example, resistance (with regard to the material properties) in the deformation area can be reduced, or webs of the ski edge blank 5 can be removed in sections. As already mentioned, a continuous web profile can also be provided, wherein the openings and webs can be produced by means of the punching device 16.

[0141] Further preferably, the punching device can be designed, independently of the embodiment shown, in the form of a rotary punching device which rotates relative to the transport direction and can preferably be displaced in the transport direction so that several punches can be punched out during the feed movement.

[0142] As can also be seen from Fig. 2, the production plant 1 can comprise a support device 54, which is provided for storing and supporting the ski edge blank 5 along the transport direction 7 after the deformation device 11 (at least) during its deformation. The support device 54 can preferably be rotatable about a rotation axis 89 arranged perpendicular to the transport plane 23, so that the support device 54 can be moved with the ski edge blank 5 during deformation thereof or the ski edge blank 5a is guided by the support device 54b, as indicated by the dashed lines. However, the support device can also be designed in the form of a multi-axis robot or comprise such a robot. Furthermore, the support device can preferably be height-adjustable along the rotation axis 89, so that the ski edge blank 5 can be guided during a displacement in a height direction, e.g., when it is deformed out of the transport plane 23.Furthermore, the support device can be designed to be adjustable in its inclination with respect to an angle to the transport plane 23, as shown in Fig. 1 with the support device 54a indicated by dashed lines.

[0143] As can be seen from the previous description, a support plane of the support device is preferably aligned with the transport plane 23 and in its basic position (when a deformation process begins) is aligned flatly with it.

[0144] As further indicated by dashed lines in Fig. 2, the production system 1 can comprise a plurality of unwinding devices 4 for providing a plurality of ski edge blanks 5, which can be configured differently from one another. The plurality of unwinding devices 4 are preferably designed in the form of a change magazine, which can also be controlled by the control device 3.

[0145] Furthermore, the production plant 1 can comprise a treatment device 19 for treating a surface of the ski edge blank 5, preferably a sandblasting device. The treatment device 19 can preferably be controlled with respect to the transport movement of the ski edge blank 5, so that this can be adjusted depending on the speed of the ski edge blank 5, e.g., a pressure is also increased at an increased speed, or is also reduced when the speed is reduced.

[0146] Furthermore, the treatment device 19 can be adjustable along the transport direction so that it can be moved, for example, with the ski edge blank 5 (in a limited area of ​​the production plant) or can be moved against it so that a treatment time can be reduced.

[0147] Furthermore, the treatment device can also additionally comprise a heating unit, e.g., for heating the ski edge blank 5 to a preferred temperature for deformation. Preferably, different treatment parameters of the treatment device 19 can also be provided from the computer program product, e.g., depending on the material used for the ski edge blank 5 and its cross-sectional geometry.

[0148] Furthermore, the production plant 1 can comprise a testing device 21 which is designed to detect at least one of the following properties of the ski edge blank 5 - with regard to its longitudinal extent at least locally in the region of the testing device;

[0149] - a hardness of the ski edge blank 5;

[0150] - a geometric cross-section of the ski edge blank 5;

[0151] - a surface roughness of the ski edge blank 5;

[0152] - a temperature of the ski edge blank 5.

[0153] - a longitudinal profile of the ski edge blank 5 (parallel to the transport direction)

[0154] The properties measured by the testing device 21 can be used to correct the deformation values ​​of the deformation device 11 or compared with them, preferably using the computer program product. Furthermore, the measured values ​​of the testing device 21 can also be used, for example, to correct the settings of the treatment device 19.

[0155] The recorded parameter of the ski edge blank 5 can be transmitted to the control device and included by the system control or by means of the computer program, and if necessary compared with already stored characteristic values, so that these are taken into account during deformation by the deformation device or the deformation values ​​are corrected.

[0156] Furthermore, the recorded parameters can be recorded or archived in the computer program product and added as material properties in a database.

[0157] Preferably, further parameters can be entered into the computer program product via the input and display device 22. Furthermore, virtual ski edge models can be selected from the computer program at the input and display device 22 in order to load them into the system control system and derive its ski edge geometry for machining the ski edge blank 5. Further explanations of the computer program product will be discussed in more detail later, although it should already be mentioned at this point that preferably all of the functions of the production system 1 described below, with regard to the actuating movements of various devices as well as the control of monitoring units, etc., can be carried out with the support of the digital processing unit or the computer program product.

[0158] As can also be seen, in Fig. 1 and 2 a coordinate system or reference system with the spatial coordinates X, Y, Z is visible, which is also arranged in the same direction in the following figures.

[0159] The X axis preferably runs parallel to the transport direction 7.

[0160] 3 and 4, the ski edge blank 5 has webs 15 and openings 14 in its web profile 27, which, as is known from the prior art, preferably have the shape of a hammer head. Depending on the geometry of a ski edge to be produced, e.g. an amount of curvature to be formed, it may be necessary to adapt the hammer heads. In this regard, they can be further processed (at least along the longitudinal extent in the region of the curvature), e.g. inline in the production line, by means of a previously mentioned punching device. According to an embodiment not shown, the ski edge blank can also have a continuous web profile (without openings), wherein the openings can preferably be produced in the production line, as already mentioned, preferably by means of the punching device.

[0161] Fig. 4 shows a cross-sectional profile of the ski edge blank 5; this preferably comprises a head profile 26 and a web profile 27; the head profile 26 forms a future outer edge of the ski edge or of a ski, and the web profile 27 is provided for embedding or anchoring the ski edge in a ski. Furthermore, the head profile 26 comprises a first side surface 28, which is arranged facing away from the web profile 27, and an opposite second side surface 29, which is arranged facing the web profile.

[0162] Preferably, the shear center M and the center of gravity S are stored (preferably in the computer program product) for a respective ski edge blank used, or they can be calculated and / or corrected based on the cross-sectional profile (e.g., when measured using the testing device), which can be taken into account in the event of deformation. Fig. 5a shows a preferred embodiment of the production system 1, in which the production system is in communication with a digital processing unit 72 on which the computer program product 73 is executed. This can be done, for example, via a web application, or via a central system that is not connected to the Internet.

[0163] As further indicated in Fig. 5a, the production plant 1 can comprise a buffer unit 61, in which the ski edge blank 5 can be transported at different speeds with respect to its movement within the production plant 1, so that, for example, an excess length section 62 can be formed in the form of a loop, or it can be retracted at a higher speed. The buffer unit 61 can further comprise a height-adjustable bearing arrangement 63, by means of which the excess length section 62 can be guided, as well as, if necessary, a monitoring unit for the excess length section.

[0164] By means of the buffer unit 61, for example, the ski edge blank 5 can be provided at a constant speed from the unwinding device 4 and can be clocked due to speed changes, e.g. during different deformation processes by the deformation device 11 in combination with the feed device 6 within the production plant 1.

[0165] Furthermore, a constant speed can also be provided within the treatment device 19 in order to subject the ski edge blank 5, for example, to constant treatment parameters.

[0166] In this regard, a second feed device 20 can preferably be provided, which can further be designed analogously to the (first) feed device and is arranged at a distance from the first feed device 6 to form the excess length section 62, as indicated by dashed lines in Fig. 5a, preferably after the unwinding device 4 and the treatment device 19. In particular, the second feed device 20 can be provided for a substantially constant transport movement of the ski edge blank 5 with respect to unwinding from the unwinding device 4, so that, for example, the weight and the mass inertia of the respective drums can be better taken into account. As can basically be seen from Fig.As can be seen from Figure 5a, further guide rollers and guide arrangements can be provided for a controlled further guidance of the ski edge blank 5 along the transport direction, which can preferably be provided between all devices of the production plant, which will not be discussed in more detail.

[0167] Preferably, a straightening device 102 can be provided, which is intended to eliminate possible pre-curvatures of the ski edge blank, in particular from the unwinding device and / or buffer unit.

[0168] The straightening device can preferably include sensory control (e.g., force measurement of guide wheels) to record further real-time parameters of the ski edge blank (and preferably transmit them to the computer program product). Furthermore, the recorded values ​​can, for example, detect an unsuitable location (e.g., reject), so that this location along the longitudinal extension is marked as reject material and can be removed by the cutting device 8. Areas containing unusable material can also be recorded, for example, by the testing device.

[0169] Furthermore, a measuring device 41 can be provided in the region of the deformation device 11, as is indicated in detail in Fig. 5b, which detects a geometry (e.g. curvature, cross-section, inclination) of the ski edge blank 5 during and / or after its deformation by the deformation device 11 and also transmits it to the control device 3.

[0170] The deformation parameters recorded by the measuring device 41 can be used for live control of the deformation process, but also for archiving deformation parameters, depending on the properties of the ski edge blank 5 used.

[0171] The deformation parameters dependent on the properties can thus be fed into the learning function of the computer program product in order to be able to use them for future processing.

[0172] Measurement and recording after deformation of the ski edge blank can also be performed by an operator, whereby the measured parameters recorded in this regard can preferably be fed to the computer program product via the input and display device—or via a mobile device. The feed device 6 can, for example, comprise (oppositely arranged) rollers for conveying the ski edge blank 5, which are rotatable relative to the transport direction, so that they draw in the ski edge blank and move or convey it along the transport direction.

[0173] Particularly preferably, the feed device 6 can comprise circumferential clamping elements 42, by means of which the ski edge blank 5 can be clamped transversely to the transport direction 7 and can be moved along the transport direction 7, as is illustrated with the clamping elements 42 in Fig. 6 with respect to the direction of rotation U.

[0174] The clamping elements 42 are guided on a track 44, which preferably has a guide 45, by means of which the clamping elements 42 can be brought closer to the ski edge blank 5 with respect to the clamping thereof, or can also be distanced from it again.

[0175] The clamping elements can be provided on one side (with respect to the transport plane), or also on two sides as shown, preferably the feed device 6 can have two clamping units 43 with clamping elements 42 opposite one another with respect to the transport plane 23, which clamping units are arranged in a mirrored manner to one another.

[0176] The respective clamping elements 42 preferably comprise a bearing element 47 facing the track 44, e.g. a wheel, by means of which they are guided with regard to their circumferential bearing on the track 44. A vertical height 48 between a lowest region 46 of the guide rail and the transport plane 23 is preferably dimensioned such that the ski edge blank 5 is clamped with regard to its head height 49 by the clamping elements 42 located in the lowest region 46 with regard to their element height 50 with a constant clamping force FK. The guide rail or an adjustment of the clamping elements with regard to the clamping force can be provided on only one side of the transport plane, so that, for example, the further clamping unit 43 can comprise circumferential clamping elements that are at a constant distance from the transport plane.

[0177] The clamping elements 42 can further preferably comprise material recesses 53, by means of which a slight elastic deformation of the clamping elements 42 (with respect to the element height 50) is enabled when clamping the ski edge blank 5, thus ensuring optimized, uniform clamping. To adjust a clamping gap 51, a height adjustment of the guide can further preferably be provided, so that the entire clamping unit 43 is height-adjustable, whereby the vertical height 48 relative to the transport plane 23 can be adjusted in order to be able to process ski edge blanks 5 of different geometries or head heights.

[0178] Furthermore, an additional calibration of the clamping unit with respect to the clamping gap can be provided, which is carried out on the basis of the measured parameters of the test device 21.

[0179] Furthermore, the clamping elements 42 can preferably be pre-tensioned along the clamping direction perpendicular to the transport plane 23 by means of a spring or the like, so that their respective eager element 47 is pressed against the track 44 when the clamping elements 42 leave the lower region 42 of the guide and the ski edge blank 5 is no longer clamped by these clamping elements 42, and the height difference during the movement along the guide is compensated by means of the pre-tensioning elements.

[0180] Preferably, the feed device can comprise a cleaning unit (not shown) which is provided for cleaning the clamping elements, in particular through which they can pass with respect to their movement in the circumferential direction.

[0181] Alternatively, according to a further advantageous embodiment not shown, a control of the clamping elements for adjusting the clamping force can be provided, e.g. an actuator instead of a link.

[0182] Regardless of the embodiment, the clamping elements 42 can preferably be designed such that they partially follow the ski edge blank 5 in the transport direction 7 (with respect to a distance along the transport direction). In particular, it can be provided that a respective clamping element follows the ski edge blank along the transport direction during clamping. In particular, this can be done such that the ski edge blank and the clamping element have the same feed rate along the transport direction during clamping, as well as a common movement path.

[0183] Fig. 7 shows a preferred embodiment of the deformation device 11. The deformation device 11 preferably comprises a bending tool 32, which is adjustable at least in one bending plane 33. The bending plane 33 can preferably be arranged perpendicular to the transport direction 7, in particular perpendicular to the transport plane 23.

[0184] The bending tool 32 can preferably be adjustable by means of an actuator along at least two axes in the bending plane 33, wherein a first adjusting axis 34 and a second adjusting axis 35 are preferably arranged perpendicular to one another.

[0185] Furthermore, the deformation device 11 can comprise a pivoting arrangement 39, wherein the bending tool 32 can be pivoted about a pivot axis 40 by means of the pivoting arrangement 39. As mentioned above, the cutting device can also be pivoted about the pivot axis 40, preferably together with the bending tool.

[0186] Preferably, the bending tool is pivotable about the pivot axis 40 in the bending plane 33, so that the pivot axis 40 is arranged perpendicular to the bending plane 33.

[0187] In principle, it should be mentioned that a pivoting of the bending tool 32 in another direction or plane is also conceivable, e.g. so that the bending plane 33 inclines to the transport direction 7 or, if necessary, an additional pivot axis can be provided for such a pivoting movement, e.g. perpendicular to the pivot axis 40.

[0188] In Fig. 7, a possible measuring device 41 is also schematically indicated, which can also be movable with the bending tool, or also rigidly relative to it.

[0189] Furthermore, the bending tool 32 preferably comprises a first bending mold 36 and a second bending mold 37, wherein the first bending mold and the second bending mold can also be arranged perpendicular to one another.

[0190] The first bending mold 36 and the second bending mold 37 each preferably have a curved surface with a respective radius of curvature, which are provided for contacting or supporting the ski edge blank 5 for its deformation.

[0191] In this regard, the bending dies 36, 37 of an embodiment of the bending tool 32 are shown in detail in Fig. 8. The first bending die and the second bending die are preferably arranged relative to one another in such a way that they form a transition region 38 in which the first and second bending dies contact one another. At the same time, the pivoting movement allows the ski edge blank 5 to be guided more effectively in the bending tool, since it is positively guided, for example, with its first side surface 28 and the bottom surface 30 in the bending dies 36, 37. When the bending tool 32 is pivoted by means of the pivoting device, the bending dies 36, 37 can be pivoted relative to the transport direction, so that they can be pivoted, for example, in the bending plane 33. Furthermore, an additional third bending die, preferably arranged parallel to the first bending die, can be provided for contact with or delimitation of the cover surface; this third bending die is not shown.

[0192] Preferably, a simultaneous pivoting of the guide device can be provided with respect to the pivoting movement, so that the ski edge blank is rotated about an axis parallel to the transport direction, preferably about the pivot axis.

[0193] This serves to produce an elastic and / or plastic pre-deformation or twisting of the ski edge blank in order to counteract unwanted plastic deformation in the form of torsion.

[0194] For example, by adjusting the bending tool 32 in the direction of the ski edge blank along both adjustment axes 34 35, a twisting of the ski edge blank 5 can occur, which can also result in torsion, which will be discussed in more detail later.

[0195] A design of a bending tool 32 shown in Fig. 8 (or also Fig. 19) further has the advantage that the ski edge blank 5 does not have to be clamped or fixed by a forming tool during its deformation, and thus retains certain degrees of freedom with regard to its feed and its deformation (even with a curvature in several spatial directions), whereby a particularly harmonious curvature of the ski edge to be produced can be made possible.

[0196] At this point, it should be noted that the bending dies illustrated in Fig. 8 preferably have the required sliding properties so that the ski edge blank 5 can be guided over the bending dies during its deformation. A lubrication device (not illustrated) can also be provided for this purpose. Furthermore, it can also be provided that the first and second bending dies are designed as separate, rotatably mounted elements that touch each other in a previously mentioned transition region and each rotate around an axis with the movement of the ski edge blank.

[0197] The adjustment of the bending tool 32 along the adjustment axes by means of the actuators, as well as the pivoting about the pivot axis 40 for deforming the ski edge blank, is preferably carried out by the control device 3, wherein a respective amount of the adjustment or pivoting movement is predetermined by the curvature of the ski edge to be produced, as well as the material characteristics of the ski edge blank, which movements are preferably supported by means of the computer-implemented method or the computer program product.

[0198] By pivoting about the pivot axis 40 and deforming it in the bending plane 33, it is possible to deform the ski edge blank 5 out of the transport plane 23 and also back into it again, so that the ski edge blank 5 can, for example, have a loop in its central section 17, which is three-dimensionally curved in the spatial direction according to the deformation. If necessary, it can also be inclined with respect to its longitudinal extent relative to the transport plane. Using such a geometry, for example, a ski edge tip can be formed which is inclined in a shovel-like manner, as indicated in Fig. 11.

[0199] In this regard, different curvature values ​​are indicated in Fig. 11, wherein, for example, the curvature (or radii) rl and r2 were produced at least by deforming the first side surface 28 of the ski edge blank 5 and the curvature r3 was produced at least by deforming the top surface 31 (or bottom surface 30, depending on the feed direction) of the ski edge blank 5. As can also be seen in Fig. 11, the ski edge blank can be designed symmetrically with respect to a center plane 70, so that, for example, the radii r2 and r3 are also arranged symmetrically, as are preferably the openings and webs. The curvature values ​​shown in Fig. 11 can, among other things, also form part of the ski edge blank parameters provided by the digital computing unit.

[0200] As can also be seen from Fig. 11, the geometry of the ski edge blank 5 can also be inclined in different spatial directions due to the deformation out of the transport plane 23, as can be seen, for example, from the course of the first side surface 28, which is inclined or oblique with respect to the transport plane 23 in the region of the central section 17 and preferably perpendicular to the transport plane 23 in the region of the legs 18.

[0201] In order to achieve such a curvature in space, preferably with a feed of the ski edge blank 5 in only one direction along the transport direction, the respective adjacent planar surface (preferably two surfaces simultaneously) of the ski edge blank 5 can be guided in an optimized manner by means of the bending tool by means of a pivoting of the deformation device, so that a respective curvature in the spatial direction can be produced.

[0202] Furthermore, in Fig. 11, a possible punching out of the webs in the curved section is indicated by dashed lines, which can be removed, for example, for reasons of rigidity, or due to collisions with each other - e.g. due to small radii of curvature, etc., whereby these punching outs are preferably carried out before the deformation by the punching device.

[0203] Furthermore, a reference point 13 is indicated in Fig. 11, which was marked (at least virtually) based on the center of the web located there. This reference point can also be used for the punching.

[0204] When producing a ski edge with two legs 18, it can also be provided that the respective legs 18 are curved towards one another during the deformation of the ski edge blank 5 in such a way that they are bent by more than 180° with respect to the longitudinal extension 9 of the ski edge blank 5, as is illustrated by the leg 18a indicated by dashed lines, which can form a leg 18 that is concavely curved when viewed from the outside during the subsequent processing and embedding of the ski edge.

[0205] As mentioned above, the inwardly bent legs 18a (or at least one longitudinal axis thereof) can intersect in a stress-free state, wherein the legs 18 are preferably kept spaced apart from each other during the manufacturing process. In general, an outward curvature of the legs can be provided by their elastic deformation, so that the legs are inclined inward in a stress-free state.

[0206] Fig. 9 shows a possible cutting device 8. The cutting device 8 comprises at least one separating element 52 for cutting the ski edge blank to length (at least with respect to the predetermined length).

[0207] Preferably, the cutting device 8 can comprise two opposing separating elements 52a, 52b, as can be seen from the detailed view E in Fig. 9, so that the ski edge blank 5 can be selectively separated in two opposite directions transversely (or vertically) to the transport direction 7, as indicated by the shearing plane 71, in order to determine the orientation of a shearing surface on the ski edge blank 5 (with respect to the shearing direction of the separating elements 52). This can be provided, for example, for the formation of a first end and a second end of a ski edge with respect to the longitudinal extent of the ski edge blank, so that the respective ends are cut to length uniformly relative to one another, so that they are aligned opposite to one another as they pass through the cutting device along the transport direction 7.

[0208] As can also be seen in Fig. 5, the cutting device 8 can preferably be arranged at one end of the production plant 1 with respect to the transport direction 7, so that with respect to the processing of the ski edge blank 5, it cuts it to length - after it has been deformed by the deformation device 11 - and is thus arranged downstream of the deformation device 11.

[0209] As already mentioned, the cutting device 8 can be pivoted about the pivot axis 40, preferably by means of the pivot arrangement.

[0210] Furthermore, a measuring unit 69 is preferably provided, which is intended for measuring, checking, and counting the openings and webs with respect to their longitudinal extent, as well as for general length control of the ski edge blank along the transport direction. Using the measuring unit 69, tolerance deviations of the webs or openings, for example, can be recorded and transmitted to the control device 3 or to a digital processing unit 72, and preferably all subsequent processing steps can be adapted or corrected to the parameters recorded by the measuring unit, preferably using the computer program product.

[0211] Preferably, a guide device 24 can also be provided, which is provided for guiding the ski edge blank 5 into the deformation device 11 or its bending tool, as well as for forming a counter-holding arrangement with respect to the deformation of the ski edge blank 5 for its stabilization.

[0212] The guide device 24 can preferably comprise at least two guide elements, which are arranged opposite one another along the transport direction 7 with respect to the ski edge blank 5, so that they guide the ski edge blank 5 along at least two opposite end faces. The guide elements can be designed, for example, as rollers or other rotatably mounted components, which are arranged straight or inclined relative to the conveying plane 25 of the production system 1.

[0213] The guide device 24 is preferably arranged rigidly with respect to the different adjustments of the deformation device 11 along the adjustment axes or is not movable with them, wherein the guide elements can be separately adjustable or adjustable with respect to their position and height and particularly preferably pivotable about the pivot axis 40.

[0214] In this regard, a possible embodiment of the guide device 24 is shown schematically in Fig. 10, in which the guide elements 56 are designed to be rotatable about a guide axis 57.

[0215] A respective guide element 56 preferably has at least two guide surfaces 59, wherein a respective guide surface is provided for contacting a planar surface of the ski edge blank 5, wherein the guide surfaces 59 are arranged perpendicular to one another, so that preferably two adjacent planar surfaces of the ski edge blank 5 abut the two guide surfaces 59 of a guide element 56.

[0216] Furthermore, the guide elements can be arranged inclined to the transport plane 23, as also shown in Fig. 10. The axis angle 58 of the respective guide axis 57 can preferably be 45 0(or 135°) relative to the transport plane 23. As further indicated by dashed lines, further guide elements 56c, 56d can preferably be designed (in the transport direction) at alternating different inclinations relative to one another, so that the receiving and guiding of the ski edge blank 5 can be designed to be largely stable. In this regard, the guide axes 57c, 57d of the further guide elements 56c, 56d are arranged offset by 90° relative to the guide axes 57a, 57b, as well as relative to the transport plane with respect to their axis angle 58c, 58d.

[0217] As can also be seen, the guide elements 56a, 56b can have conical guide surfaces 59 with respect to their respective guide axes 57a, 57b, which are designed to extend obliquely according to the axis angle 58a, 58b, so that they are arranged flat (or tangential) to the respective first side surface 28 and second side surface 29 or flat to the bottom surface 30 and the top surface 31 of the ski edge blank 5 when guiding it. The opposing guide elements 56a, 56b can have different geometries, as shown, or they can also be designed identically.

[0218] At this point, it should be mentioned that the production plant 1 also has further such or similar guide elements, which can be provided for guiding the ski edge blank along the transport direction 7 and can optionally be used for a counter-holding function, e.g. in the area of ​​the punching device.

[0219] As can be seen in principle, it is preferably provided that the two guide surfaces arranged opposite one another along the transport direction 7 with respect to the ski edge blank 5 are designed in such a way that a respective guide element with two guide surfaces rests against at least two planar surfaces of the ski edge blank, so that the two opposite guide elements 56 together guide 4 planar surfaces.

[0220] In a preferred embodiment, these are the 4 planar surfaces and the top surface 31, the first side surface 28, the bottom surface 30, and the second side surface 29, wherein two adjacent surfaces (across a longitudinal edge) are each guided by a guide element. Furthermore, the ski edge blank 5 can also be supported by means of a respective guide element 56 in a respective longitudinal edge located between two adjacent surfaces, thereby enabling particularly favorable support with respect to deformation by the deformation device or the bending tool 32. Another possible embodiment of the guide device 24 and the guide elements 56 is shown in Fig.20, in which a respective guide element 56 also preferably has at least two guide surfaces 59, wherein a respective guide surface 59 is provided for contact with a planar surface of the ski edge blank 5 and the guide surfaces 59 are arranged perpendicular to one another, so that preferably two adjacent planar surfaces of the ski edge blank 5 can contact the two guide surfaces 59 of a guide element 56.

[0221] As further indicated in Fig. 20, the guide elements 56 can be adjustable along an axis, preferably along their guide axis 57, so that a receiving space between the two guide elements 56 or between their opposite guide surfaces 59 is adjustable in order to adapt it to different ski edge blank cross-sections or to compensate for tolerances of a ski edge blank, or to press the guide surfaces onto the ski edge blank by means of a contact pressure.

[0222] In this regard, a width 97 and height 98 of the receiving space are indicated in Fig. 20, which width 97 and height 98 are each formed between the mutually facing and opposite guide surfaces 59 of the guide elements 56e, 56f and can be adjusted by adjusting the respective guide elements 56e, 56f with respect to their guide axes 57e, 57f.

[0223] Furthermore, the guide elements 56 can be designed in the form of interchangeable tools so that their heads can be exchanged with respect to the receiving space to be adjusted.

[0224] As further indicated in Fig. 5b, the production system 1 can comprise a cleaning device 60, which is provided for cleaning and removing any residual components from the surface of the ski edge blank 5, e.g., iron dust. The cleaning device 60 is preferably arranged along the transport direction upstream of the forming device 11. The cleaning device can, for example, comprise pneumatic means, as well as a line for removing material.

[0225] Furthermore, the cleaning device 60 can preferably be provided between the feed device 6 and the guide device 24. Furthermore, Fig. 5a shows a collection container, which is provided for receiving waste material from the production system 1, which is transferred to the collection container by a discharge device. For example, material punched out by the punching device.

[0226] Fig. 12 shows a possible design of the support device 54.

[0227] As mentioned above, the support device 54 can be rotatable or pivotable about a rotation axis 89, as well as height-adjustable with respect to a direction perpendicular to the transport plane and / or adjustable with respect to an inclination at an angle 651 relative to the transport plane 23, so that it can be guided along with the ski edge blank 5 to be deformed. It can also be provided that the support device comprises an industrial robot 54a, in particular a multi-axis robot, which guides the ski edge blank with respect to its deflections from the deformation device and is configured to deposit it or transfer it to another device.

[0228] In a basic position or standby position of the support device 54, in which a first end of the ski edge blank 5 is guided for the first time by the deformation device 11 along the transport direction 7 in the direction of the support device 54, the support plane 64 of the support device 54 is preferably arranged parallel to the transport plane 23, in particular it can lie in the transport plane 23.

[0229] During a respective deformation movement, the support device 54 (or of the industrial robot) is pivoted relative to the rotation axis 89 and / or adjusted in height and / or inclined in its angle of inclination 65. These adjustment movements are preferably coupled to the feed movements of the feed unit and the adjustment movements of the deformation devices (and the resulting movements of the ski edge blank) via the control device and particularly preferably supported by the digital processing unit using the computer program product.

[0230] The movements can further be supported by a monitoring unit 66, which is provided for monitoring the ski edge blank in the region of the support device. Furthermore, deviations in the movement of the support device relative to the ski edge blank can be detected and provided to the digital processing unit for updating the computer program product. Furthermore, the support device 54 can comprise at least one driver arrangement 67 that is adjustable relative to the support plane 64, which is provided at least for supporting the ski edge blank and preferably follows a reference point 68 of the ski edge blank 5. The reference point 68 can, for example, be a longitudinal end of the ski edge blank 5, or also a central section, in particular the aforementioned reference point 13. An actuator drive of the driver arrangement 67 is not shown; the adjustment axes are indicated by dashed lines.

[0231] Preferably, the driver arrangement 67 can further be provided for transferring the ski edge blank 5 after its deformation, or a produced ski edge, to a subsequent device or a storage device, as indicated by the schematically illustrated storage device.

[0232] The carrier assembly 67 is shown only roughly schematically; it can further comprise a gripping element, by means of which, for example, the ski edge blank can be transferred along the support plane 64 to another device. The carrier assembly 67 can also be configured using an end effector of the industrial robot.

[0233] Furthermore, it can also, for example, block the ski edge blank 5 with regard to its movements in predetermined directions, so that it cannot deflect uncontrollably, for example, in the vertical direction (Z-axis).

[0234] Preferably, a further manipulation arrangement 101 can be provided in the region of the support device 54, which is intended to guide the legs 18 of the ski edge blank 5 so that they do not cross each other when the central section is bent. Furthermore, the manipulation arrangement 101 and / or the industrial robot 54a can be configured to insert a spacer element 99 between the legs 18, which spacers the legs from each other and can optionally also be transferred to another device with the fully formed ski edge blank 5 or the ski edge 2.

[0235] As further evident from Fig. 12, regardless of the illustrated design of the support device 54, different ski edges 2 can be produced by means of a production system 1 according to the invention, which can, for example, form a circumferential profile, or a ski edge with two opposing legs connected by a ski tip (the ski edge), or, for example, only a left or right ski edge, which thus comprises only one curved leg, or even only one ski tip. A left or right ski edge can also have an inward-facing leg, which, with respect to its flexural elasticity, can be pressed outwards during use.

[0236] This makes it clear that, in principle, any ski edge geometry can be produced using the production plant or system according to the invention.

[0237] Fig. 13 shows a possible embodiment of an unwinding device 4, wherein several storage units in the form of drums with optionally different ski edge blanks 5, 5a, 5b are provided, wherein a respective ski edge blank or its storage unit can be loaded from the production plant 1 (via the control device or a digital computing unit).

[0238] Fig. 14 schematically shows a computer program product 73 which is used in the execution of a computer-implemented method by a digital computing unit 72 for providing parameters for the production of a ski edge, or is executed by the digital computing unit.

[0239] The computer program product comprises a database in which different ski edge data 75 for producing a ski edge are stored, wherein the ski edge data can include both characteristic values ​​of the ski edge or the ski edge blanks themselves as well as characteristic values ​​for a production plant for producing the ski edge.

[0240] Furthermore, different ski edge blank profiles and types can be stored in the ski edge data or database, as well as associated cross-sectional profiles and material properties and other metadata. Preferably, an application can also be provided that is configured for the user-specific creation of new ski edge blank profiles or geometries, as well as new material properties, for example, in the form of a CAD model.

[0241] Furthermore, the computer program product preferably comprises an application for processing and displaying a virtual ski edge 76 or possibly also a virtual ski model, which can be provided to an input and display device or visualized there for a user.

[0242] The computer program product is preferably configured to derive the virtual ski edge 76 from a virtual ski model 81.

[0243] Based on a (spatial) geometry of the virtual ski model, a virtual ski edge can be derived, which can preferably have the same curvatures and courses in space as the virtual ski model. This can be necessary, for example, if a (real) ski or a prototype or the like is provided whose external geometry is known or is measured using 3D measuring systems and whose measuring parameters are entered into the system or transferred so that a ski edge to be manufactured can be derived from the measured ski with the aid of a computer. In this case, it can preferably be provided that a thickness (e.g. head height) of the ski edge can be determined by the computer program product or can be specified by a user, or can be selected from a virtual ski edge blank.

[0244] A 3D polyline or spline (preferably CAD) is derived from the virtual model, which corresponds to the profile of the ski edge to be produced. The individual deformation steps required to produce the 3D spline 82 or the virtual ski edge 76 from a given (linear) ski edge blank profile are virtually derived from the 3D spline.

[0245] From the 3D spline 82, for example, the deformation process of the ski edge blank 5 can be derived in reverse order with computer support, so that starting with the last deformation step, the ski edge blank 5 is virtually reshaped into a straight profile and, in each respective deformation step, the deformation parameters required for the real deformation of the ski edge blank 5 in the respective area are simulated.

[0246] Furthermore, a starting point (preferably corresponding to a front end of the ski edge blank) can be determined. Starting from this point, a respective curvature of the virtual ski edge is measured in the spatial direction along the longitudinal extension, and a respective deformation step is assigned to a respective curvature, up to an end point of the virtual ski edge with respect to its longitudinal extension. Based on the measured geometries of the virtual ski edge or the 3D spline, ski edge blank parameters 77 can be derived using the computer program product or the digital processing unit.

[0247] Furthermore, the previously mentioned methods can be used to derive the previously predetermined length, or the respective end points for cutting to length, as well as a previously mentioned reference point, as well as positions for punching, etc.

[0248] From the respective deformation steps of the individual curvatures (as well as further processing steps; e.g., punching), processing parameters 78 can be created using the computer program product. From these parameters, a processing program 74 can then be created, which can be provided to the production system 1 and used to process the ski edge blank. The processing program 74 can, for example, include the adjusting movements (and optionally pivoting movements) of the deformation device and the associated feed movements of the feed device, which in combination correspond to a deformation with respect to a specific curvature - preferably further dependent on a respective ski edge blank type, e.g., different cross-sectional profiles of the ski edge blank to be used. Furthermore, the tool geometries of the tools to be used are preferably incorporated into the processing parameters.

[0249] Thus, the ski edge data 75 or the database of the computer program product can further comprise a selection of different tools and tool geometries for the same machining step, wherein a tool selection can be prioritized or determined for the respective ski edge blank parameters 77 to be produced, whereby the machining program 74 can subsequently comprise a tool change.

[0250] Preferably, the processing program can be provided for an operator (e.g. at the input and display device), e.g. in the form of a simulation, and if necessary, changes and / or additions can be made by the user, e.g. additional punchings, for example for screw holes.

[0251] It can be provided that the virtual ski edge corresponds to a finished ski, which may include a machined edge, so that the final outer dimensions are smaller than those of the ski edge to be manufactured (using the production system). This can be due, for example, to post-processing, such as edge grinding or the like, so that the ski edge data includes, for example, a grinding allowance, which is taken into account when creating the processing parameters.

[0252] Furthermore, a coating thickness or the like can also be taken into account, as well as other post-processing parameters.

[0253] The transfer of the virtual ski edge into the ski edge blank parameters can therefore also include manufacturing steps that may not be carried out in the manufacturing plant, but are relevant for processing by the manufacturing plant.

[0254] Furthermore, it can be provided that the computer program product is configured to mark individual positions or areas of the virtual ski edge for a user, e.g. in the case of insufficient database information, which can be provided to a user in the form of feedback in order to supplement or correct the required parameters by means of a user input.

[0255] Furthermore, a digital twin of the ski edge blank 87 of the ski edge to be produced can preferably be created, the deformation of which is documented compared to the actual deformation of the ski edge blank 5 (e.g., by a previously mentioned measuring device 41) and archived in the computer program product, and preferably compared and adjusted using the previously described derived geometry of the virtual model. In this regard, a digital twin of the production facility 88 can also preferably be provided, as shown in Fig. 16 with the virtual production facility.

[0256] In the event of changes in the real deformation profile compared to the virtual deformation profile, the change values ​​are stored and supplemented in the database with the ski edge data 75 of the computer program product 73 in order to improve the creation of the machining program 74 for the real deformation processes as well as the method for the virtual derivation of the ski edge geometry in order to continuously update the computer program product.

[0257] Furthermore, the computer program product can preferably take into account additional processing steps of the production plant, e.g., those of the treatment device, so that, for example, a change in the profile cross-section of the ski edge blank due to a treatment process, e.g., sandblasting, is taken into account. Thus, the processing program 74 can, for example, include additional processing steps, such as sandblasting.

[0258] Furthermore, it can be provided that the computer program product (or the control device) is configured to determine, depending on a ski edge blank type, positions and geometry of the punched-outs with respect to the webs and openings along the longitudinal extent of the ski edge blank to be used, which can also be provided to the production plant 1 in the form of the processing program.

[0259] In this regard, the testing device (or a further measuring unit 69 or detection unit) preferably comprises a measuring arrangement for optically checking and / or measuring the openings and / or webs, so that the actual position and / or geometry of the punched-out portions can be passed on to the punching device.

[0260] At this point, it should be mentioned that, in principle, the machining program can include all commands of the production plant that can be initiated by the control device 3.

[0261] With regard to the deformation of the ski edge blank, the current orientation of the ski edge blank (during the manufacturing process) can also be taken into account, since, for example, a ski edge to be produced is preferably designed symmetrically with respect to a center plane (as mentioned with respect to Fig. 11), but the respective symmetrically arranged curvatures are moved in opposite directions during their manufacture with respect to the feed direction of the feed unit and the movement of the deformation device (starting from the center section) and can therefore possibly have different material properties and friction values, so that the required deformation parameters for two symmetrically formed curvatures can be different.

[0262] Furthermore, the computer program product can be configured to derive new deformation values ​​(based on new curvature values) based on the parameters stored in the database by using the nearest known deformation values ​​(based on known curvature values) and interpolating them to determine new deformation parameters, which can be simulated in a further step (preferably using digital twins) and, if necessary, provided to a user (e.g., via the display device) (and adapted by the user if necessary). Furthermore, both ski edge blank parameters and known machining parameters can be interpolated in this regard.

[0263] Furthermore, further external parameters 90 can be transmitted to the computer program product 73 or the digital computing unit 72 from an external system 100, which can be processed by the computer program product on the basis of the ski edge data 75 and preferably the digital twins, and an evaluation can be transmitted to the external system 100 in the form of internal parameters 89.

[0264] The external parameters 90 can, for example, include a request for a ski edge to be produced with respect to a blank material, as well as a quantity of ski edges to be produced, wherein the computer program product, on the basis of the ski edge data 75 and / or the digital twins, collects, for example, information about production times or cycle times of the ski edge(s) to be produced, as well as a total length of a ski edge blank material to be used (with respect to the individual ski edges and any waste products that may arise) and provides this to the external system 100 in the form of the internal parameters 89.

[0265] For example, the external system can include production planning software that communicates with the digital processing unit, such as an MES (Manufacturing Execution System), or a product data management system PDM.

[0266] The created internal parameters 89 can, for example, comprise a quantity of a required raw material for the manufacturing plant for producing at least one ski edge and / or a duration of a manufacturing process for the at least one ski edge by the manufacturing plant and / or a required output of the manufacturing plant for producing the ski edge.

[0267] Furthermore, the data collected by the computer program product may be made available for use in a Digital Product Passport.

[0268] Furthermore, it can be provided that the computer program product 73 or the digital processing unit 72 is configured, upon request from a user for the production of a ski edge, in the form of an external model 83 that is transmitted to the digital processing unit - based on the ski edge data stored in the database - to provide feedback to the user regarding the possibility of producing the ski edge using a virtual ski edge model or a virtual ski model, wherein, in the case of parameters not stored, the respective areas in the virtual ski edge model are marked or displayed using the virtual ski edge model. Preferably, in a further development, changes to the respective areas are proposed based on parameters already stored.The communication regarding an external model 83 can further be carried out with a previously mentioned external system, so that after the processing of the external model 83, the previously mentioned internal parameters can be created on the basis of this, e.g. production time and materials used.

[0269] In this regard, Fig. 15 a) to c) show a possible scheme in which an external virtual ski model is transmitted to the digital computing unit 72 by a user by means of an input element 84.

[0270] According to a) the digital processing unit compares the external model 83 with the ski edge data 75 of the computer program product and determines in the first instance whether a virtual ski edge can be derived or provided on the basis of the provided data, or whether the processing unit cannot use the provided external model 83 - with regard to the latter, this information is transmitted to the input element.

[0271] If the external model 83 can be used, the digital processing unit 72 creates a virtual ski edge 76 and / or a 3D spline 82 and provides feedback 85 on the basis of this, the feedback (85) comprising at least one of the following information;

[0272] - information (Yes / No) that ski edge blank parameters 77 can be created based on the external virtual model (and / or)

[0273] - an error message if no ski edge blank parameters 77 can be created based on at least one area of ​​the external model 83, wherein the area is marked in a virtual image of the external model 83; as indicated in Fig. 15 b). - Furthermore, this feedback can include a suggested change regarding at least one area of ​​the external model 83 if no ski edge blank parameters 77 can be created based on the area.

[0274] In response to the change suggestion or to the error feedback, a user input 86 can be made, whereby a change of the virtual ski edge 76 is carried out by the digital processing unit - according to Fig. 15 c)

[0275] Thereafter, a further feedback 85 is sent to the input element, wherein the feedback already includes final information regarding the ski edge to be produced, or a return to Fig. 15b) (loop), so that further user input is required for the change.

[0276] As mentioned at the beginning, the computer program product can be executable in the form of a web application, via a cloud application or the like, so that several manufacturing plants are connected to the computer program product and the computer program product can receive information for improvement via several manufacturing plants and, conversely, can also provide and update this information to several plants.

[0277] Fig. 17a) to c) shows possible deformation steps for producing a ski edge.

[0278] The ski edge blank 5 is guided along the transport direction 7 over the bending tool 32 with its first longitudinal end 91 with respect to its longitudinal extension 9. For the deformation, the bending tool 32 presses against the ski edge blank 5 transversely to the transport direction 7 by means of at least one of its bending dies, comprising at least the first bending die 36 and the second bending die 37, so that the ski edge blank is also deformed or bent transversely to the transport direction 7 during its feed movement.

[0279] The bending dies are preferably pressed into place by adjusting the bending tool 32 relative to the first adjustment axis 34 and / or second adjustment axis 35 by the deformation device. The ski edge blank 5 is preferably guided into the bending tool by the guide device 24, indicated by dashed lines, and stabilized against the deformation movement.

[0280] Furthermore, it should be mentioned that in Fig. 17a) to c) continuous webs are shown on the ski edge blank 5, whereby these could be removed again with regard to the curvature to be produced according to previously described methods, preferably before the deformation shown, in particular in order to produce the most harmonious curvature possible on the outer edge.

[0281] According to the current orientation of the bending tool 32 relative to the ski edge blank shown in Fig. 17a, the ski edge blank 5 can be deformed in a direction perpendicular to the transport direction 7 and parallel to the transport plane 23, for example, by adjusting the first adjusting axis 34. By adjusting the second adjusting axis 35, the ski edge blank 5 can be deformed perpendicular to the transport plane 23 relative to the current orientation. By simultaneously advancing the ski edge blank 5, a curvature profile in the spatial direction is thus created.

[0282] As further indicated in Fig. 17a, the support surface can be in a standby position at the beginning of the deformation process, in which its support plane 64 is parallel to the transport plane 23 or is arranged lying therein.

[0283] According to Fig. 17b, a first leg 18 has already been formed by means of several adjusting movements of the bending tool 32 and feed movements of the ski edge blank 5, whereby the ski edge blank 5 is located in the region of the bending tool 32 with respect to its longitudinal extent by means of its central section 17. The leg 18 is shown cut away with respect to its length for simplified illustration.

[0284] In the illustrated step, a shovel shape is bent so that the ski edge blank 5 can be inclined with respect to its already formed section with the first longitudinal end 91 in a different spatial direction relative to the transport plane 23, wherein the already formed section can be preferentially guided so that the ski edge blank 5 does not deform undesirably due to its own weight, as indicated by the inclined support plane 64.

[0285] With respect to the blade shape, the bending tool 32 was adjusted at least perpendicular to the transport plane (in the positive direction of the Z-axis), so that the ski edge blank 5 is also curved upwards with respect to an initial region 93 of the blade shape, for example, by the first bending die 36 pressing against the bottom surface 30. At the same time, the second bending die 37 presses against the first side surface 28 to bend it.

[0286] As further indicated in Fig. 17b, the bending tool 32 can be pivoted relative to the pivot axis 40 by an angular amount 92 (preferably in the bending plane), so that the ski edge blank 5 additionally rotates slightly about an axis along the transport direction 7 with respect to its deformation during its feed movement over the bending tool 32. As further indicated, the first adjusting axis 34 and the second adjusting axis 35 can also be pivoted, as can the guide device 24.

[0287] As can be seen or indicated in Fig. 4 in this regard, due to the non-symmetrical profile of the ski edge blank 5, the main axes of the area moments of inertia, which run through the center of gravity S of the ski edge blank 5, are not parallel to the axes Y, Z or to the planar surfaces of the ski edge blank.

[0288] Furthermore, the shear center of the cross-sectional profile can also be adjusted with respect to the removal of the webs, for example if areas are bent with respect to a curvature whose webs are previously removed.

[0289] With regard to the torsion shown in Fig. 17b, the ski edge blank can preferably be twisted by means of the guide device 24 in order to counteract undesired deformation.

[0290] A bend along Y and Z (“oblique bend”) results in a rotation about X or the transport direction, which can be compensated by means of the induced rotational movement of the guide device 24.

[0291] As already mentioned, the position of the pivot axis 40 can preferably be adjustable in this regard, so that this or the pivot arrangement can be adapted to different cross-sectional profiles.

[0292] Preferably, this can also be done by the computer program product, which can preferably also include calculating the shear center and / or the center of gravity, as well as the mentioned principal axes. - 41 -

[0293] The bending tool is located in a central region in Fig. 17b with regard to the blade shape to be formed, so that with regard to the further deformation, the ski edge blank 5 is further pre-formed in a subsequent step with regard to the curvature on the first side surface and, due to the bending carried out in the spatial direction (Z+Y with feed in X), is simultaneously deformed in an opposite direction starting from the center of the blade shape. In this case, the first bending die 36 continues to be pressed against the bottom surface 30 of the ski edge blank 5 so that it receives a downward curvature with regard to its longitudinal extent. At the same time, the second bending die 37 is pressed against the first side surface 28 to produce or further shape the curvature on the first side surface, so that, for example, two profiles symmetrical with respect to a central plane can be created, e.g. legs.

[0294] Fig. 17c, the second section of the blade shape was formed, starting from the central region, wherein the bending tool 32 (and the guide device 24) was subsequently pivoted again about the pivot axis (back) - namely the position shown, so that in an end region 94 of the blade shape by means of the first bending mold 36 the ski edge blank can be deformed upwards (in the positive Z direction), and this is designed to run in the same way with respect to the starting region 93 and the end region 94 relative to the transport plane (or symmetrically to a central plane).

[0295] Also indicated is the driver assembly 67, which can be provided to assist in guiding the ski edge blank 5 during its deformation, as well as for its removal after its deformation and cutting to length. Preferably, this can also be oriented toward a reference point 13. Furthermore, a spacer element (not shown) can be arranged between the legs 18, as mentioned in the previous description.

[0296] Furthermore, the communication between the production plant and the digital processing unit 72 is indicated in Fig. 17c. As indicated by dashed lines, the respective deformation states of the ski edge blank 5 can be recorded, for example by means of at least one measuring device 41, and the different actuating movements of the deformation device - and optionally other devices of the production plant - can be documented and transmitted to the digital processing unit 72 in the form of real deformation parameters 79 and real machining parameters 80. In the event of deviations of the real deformation parameters 79 from the calculated target values ​​(preferably of the virtual model), the recorded and used parameters are stored in the database and, preferably, the machining program is adjusted in the form of correction values. As can also be seen, the machining parameters 78 andthe machining program 74 can be provided for different devices of the production plant, preferably centrally managed by the control device 3.

[0297] As further apparent from the figures as a whole, with regard to the deformation of a ski edge blank 5 by means of a deformation device according to the invention for producing the curvatures, it is predominantly - and particularly preferably exclusively - provided that the bending tool is pressed against the bottom surface and the first side surface in order to deform the ski edge blank.

[0298] Finally, Fig. 18 shows exemplary possible manufactured ski edges 2, wherein a circumferential ski edge 2 has a central section 17 and two shaped legs 18, and the further ski edges 2 comprise, for example, a left ski edge 2, as well as a possible ski tip, which were manufactured according to a predetermined length with respect to their longitudinal extent for the respective areas of use.

[0299] As can also be seen, in the ski edge 2 with the two legs 18 in the middle section 17 (as well as in the ski tip), some webs 15 were removed, preferably by means of a punching device of the production plant, which were also preferably determined with computer support.

[0300] Furthermore, a spacer element is indicated by dashed lines between the legs 18, which keeps them spaced apart from one another, the ski edge preferably having a curvature which presses the legs 18 against one another, which is preferably formed in the central section 17.

[0301] Fig. 19 shows a further possible embodiment of a bending tool 32, wherein the bending tool 32 comprises a rotating body mounted with respect to a rotational axis 95. As can also be seen, the rotational axis 95 is inclined at an angle, preferably by 45°, relative to the adjustment axes of the deformation device (and arranged in the bending plane 33). The first and second bending dies 36, 37 preferably each comprise a bending surface 96 that is conical (in particular 45°) with respect to the rotational axis 95, wherein the two conical bending surfaces 96 are tapered towards one another.

[0302] As can also be seen, the bending tool 32 can rotate about its rotation axis 95 with the feed movement of the ski edge blank 5 along the transport direction 7.

[0303] The height of the rotation body or the conical bending surfaces 96 with respect to the rotation axis 95 can be dimensioned such that the conical bending surfaces are slightly larger than the first side surface 28, if, for example, a separate bending tool is provided for each ski edge blank cross-sectional profile.

[0304] In principle, however, the height can also be selected in such a way that it is suitable for all possible cross-sectional profiles (e.g. with regard to a head height and a vertical extension of the head profile).

[0305] Basically, with regard to the adjusting movements of the bending tool 32 along the first and second adjusting axes 34, 35, as well as the pivoting movements with respect to the pivot axis 40, reference is made to the description of the preceding figures, or also to the described deformation devices 11, e.g. according to Fig. 7.

[0306] Furthermore, the bending tool 32 shown in Fig. 19 can be used analogously for the deformation steps described in Fig. 17.
