Description

[0001] The invention relates to a modular assembly arrangement comprising textile tool modules and a method for assembling the modular assembly arrangement.

[0002] The use of textile tool modules in textile machines has been well-established for many decades. Textile machines include, for example, knitting machines, sewing machines, warp knitting machines, and needling machines for the production of nonwovens. Textile tool modules typically comprise a multitude of textile tools, which are encased side-by-side to form a single module. Using textile tool modules reduces the setup time of textile machines because they allow for the assembly of numerous textile tools in a single step. The larger the textile tool modules, the more textile tools can be assembled simultaneously, thus reducing machine downtime.One disadvantage of textile tool modules is that if a single tool malfunctions, the entire module must be replaced. This is expensive because the still-functioning tools within the module also need to be replaced. Furthermore, it is unsustainable to have to discard the still-functioning tools of the module. Therefore, textile tool modules should not be too large. In this balancing act between cost and sustainability on the one hand, and assembly times on the other, textile tool modules with widths of 1 / 2 inch to 2 inches have become the standard in the market in recent years. However, the need to be able to quickly mount as many textile tools as possible on a single textile machine remains.

[0003] EP3587644A1 proposes a detachable connection between several textile tool modules (knitting tool holders). Several textile tool modules are bonded together with a rod-shaped connector to form a module assembly, with the adhesive bond being detachable. The textile tool modules can thus be mounted together on a textile machine as a module assembly. After assembly, the rod-shaped connector can be detached to allow for the replacement of individual textile tool modules in case of a defect. However, in this embodiment, the textile tool modules must be aligned in a very complex manner before being bonded to the connector. After bonding, there is a risk that the textile tool modules will shift relative to each other. Therefore, the production of such module assembly assemblies is expensive and prone to errors.At the same time, the number of textile tool modules per module assembly arrangement cannot be changed after gluing, which is why the module assembly arrangement cannot be adapted to the working width of different textile machines.

[0004] The present invention is therefore based on the objective of providing a module assembly arrangement and a method for assembling the module assembly arrangement that can be variably adapted to different textile machines and enable cost-effective production of the module assembly arrangement in good quality.

[0005] The problem is solved by a modular assembly arrangement according to claim 1 and a method for assembling the modular assembly arrangement according to claim 14. A modular assembly arrangement according to the invention comprises at least two textile tool modules, each of the at least two textile tool modules being equipped with a module body. The module bodies of the at least two textile tool modules carry several textile tools arranged side by side in a longitudinal direction. The textile tools are generally fixedly connected to the module bodies. Advantageously, the textile tools are cast into the module body. For this purpose, the module body can be made of a castable material, for example, a metal or a plastic.Textile tools can be any tools used in textile machines that preferably have direct contact with yarn, thread, or fiber during operation, such as knitting needles, warp needles, dies, punching needles, felting needles, sewing needles, tufting needles, or tufting knives. The textile tools of the at least two textile tool modules have their main direction of extension along a vertical axis that runs perpendicular to the longitudinal axis. At least in the case of punching needles, felting needles, sewing needles, tufting needles, knitting needles, and warp needles, the main direction of extension runs along the shank of these textile tools. In the module assembly arrangement, the at least two textile tool modules are detachably connected to one another. This connection allows the at least two textile tool modules to be handled together, which significantly simplifies assembly and reduces setup time.The connection is sufficiently strong to ensure that the textile tool modules form a single unit for assembly. Therefore, the connection will not loosen under the assembly forces typically applied to textile tool modules. However, the connection can be released by applying a controlled force, meaning it can be disconnected after the module assembly has been mounted on a textile machine. This allows the textile tool modules of the assembly to be individually replaced after installation on a textile machine, if necessary. Preferably, the connection can be released manually. The module assembly can be manufactured particularly cost-effectively and to a high standard if the at least two textile tool modules are held in their intended position within the assembly, allowing for a degree of vertical adjustment relative to each other.The target position is the position the textile tool modules occupy in the module assembly arrangement when connected. The adjustment range is the distance by which the textile tool modules can move relative to each other vertically. The textile tool modules can also be moved relative to each other longitudinally, for example, if they are rotatable relative to each other. Rotating them relative to each other moves the textile tool modules both vertically and longitudinally. The textile tool modules can then be aligned relative to each other, or relative to the textile machine, in both the longitudinal and vertical directions.Using the methods described above, the textile tools can be adjusted vertically at least to such an extent that, when mounted on a textile machine, they can be individually positioned or adapted to their target position on the machine. Inaccuracies arising from the manufacturing of the module assembly can thus be easily compensated for, enabling cost-effective production of the assembly with low requirements for the accuracy of the textile tool module alignment. Advantageously, the vertical adjustment range is limited. This limitation can be achieved by a vertically limited clearance between the textile tool modules. With the module assembly described above, several textile tool modules can be positioned simultaneously on a textile machine.Due to the detachable connection of each two textile tool module in the modular assembly, the number of textile tool modules can be easily varied by adding or removing individual modules. This allows the assembly to be adapted to different sized textile machines and the individual requirements of assembly operators and customers. Simultaneously, each textile tool module can be individually aligned vertically on the textile machine during assembly. This reduces the effort required for readjusting the textile tool modules after assembly. Advantageously, the modular assembly described above is arranged or mounted on a bar of a textile machine that extends primarily in the longitudinal direction. The longitudinal direction is therefore the main extension direction of the bar, and the bar serves as a support for the textile tool modules.Bars typically have a cross-section that is constant along the longitudinal direction and / or are preferably hollow. Textile machines with such bars include, for example, warp knitting machines or tufting machines. Advantageously, a bar has a surface suitable for aligning the stops of the textile tool modules against it. For the purposes of this patent application, this surface is also referred to as an edge. The surface normal of the edge preferably points in the vertical direction. Advantageously, the textile tool modules have stops with which they can be aligned vertically against the edge of such a bar. The stops are applied to the edge during assembly. Such stops are already well known to those skilled in the art, for example, from commercially available needle punch modules.The stop can include a raised section that is vertically raised above, projecting above, or protruding from the surrounding surfaces of the textile tool module on which the raised section is located. It is particularly advantageous if each textile tool module includes at least two stops. The stops are advantageously spaced apart longitudinally. The greater the longitudinal spacing of the stops, the more precisely the textile tool modules can be aligned with the edge of the bar. The stops are advantageously shaped to allow point or line contact with the edge of the bar. Point contact can be achieved, for example, by a conical, pyramidal, or hemispherical raised section.Linear contact can be achieved, for example, by a semi-cylindrical protrusion. This protrusion is positioned so that its curved circumferential surface extends vertically beyond the surrounding surfaces of the textile tool module. However, the textile tool modules of the modular assembly can also be aligned vertically on a textile machine, even without stops, for example, by manual adjustment. Manual adjustment, however, increases the assembly effort, requiring additional work by experienced and specially trained personnel.

[0006] Advantageously, the modular assembly includes at least one connector through which the textile tool modules are linked. The connectors can be released by applying a controlled force, meaning they can be disconnected after the modular assembly has been mounted on a textile machine. This prevents the connector from interfering with the operation of the textile machine. Preferably, the connectors can be released manually. This makes handling the modular assembly particularly easy. Advantageously, each connector links only two adjacent textile tool modules, allowing additional textile tool modules to be added to the assembly using further connectors. This makes the number of connectors and textile tool modules particularly flexible and adaptable to different textile machines.The connector serves to improve and simplify the assembly of multiple textile tool modules on a textile machine. Once the textile tool modules are attached to the machine, the connector advantageously has no function required for the operation of the textile machine. In other words, the connector is not needed for the operation of the textile machine.

[0007] Further advantages arise if the module assembly arrangement includes at least one male and at least one female connector, wherein the at least one male and at least one female connector interlock to detachably connect the textile tool modules. Interlocking male and female connectors are corresponding connectors, i.e., matching counterparts. Such connectors are, for example, a positive form and a corresponding negative form, or a plug and its corresponding socket. When correctly aligned, interlocking connectors create a connection. The connectors can be integral parts of the textile tool modules, particularly the module bodies.The fasteners can also be part of the connector or other components of the module assembly. They can be integrally manufactured with the textile tool modules, the module bodies, the connector, or other components of the module assembly. Alternatively, they can be bonded to the material, for example, by gluing.

[0008] Further advantages arise if the at least one male connector is a projection that engages with the at least one female connector, with the female connector at least partially encompassing the male connector. There can be vertical play between the male and female connectors to allow for vertical adjustment of the textile tool modules. The female connector can be formed by one or more recesses that fit the projection. Advantageously, however, the female connector is formed by several projections arranged relative to each other in such a way that they encompass the male connector. These projections are thus arranged so that the male connector can be positioned between them. The textile tool modules each have at least one male and / or female connector.For example, each textile tool module can have a male and a female connector arranged in such a way that identical textile tool modules can be connected to each other when lined up side by side lengthwise. The male and female connectors of adjacent textile tool modules then interlock.

[0009] Advantageously, the male and female connectors form a tongue-and-groove connection, where the male connector is a tongue and the female connector is a groove. A tongue is an elongated projection. A groove is a slot-shaped or elongated recess. In a tongue-and-groove connection, the tongue engages in the groove to create a connection. The tongue and groove are movable relative to each other in the vertical direction of the module assembly. Advantageously, this movableness is ensured by the fact that the tongue and groove have a constant cross-section or shape along the vertical direction. Tongue-and-groove connections can be manufactured very cost-effectively and with very high quality. They are therefore particularly suitable for module assembly.It is particularly advantageous if the tongue and groove are also longitudinally displaceable relative to each other, so that the textile tool modules are held movable relative to each other in the longitudinal direction. The textile tool modules, which are thus held movable both vertically and longitudinally in the module assembly arrangement, can then be aligned even more precisely when mounting the module assembly arrangement on a bar. Further advantages arise if the textile tool modules of the module assembly arrangement each have a groove and a tongue. The tongue of one textile tool module can then always engage in the groove of the next textile tool module. In this way, one textile tool module can be aligned with another.Furthermore, this prevents the textile tool modules from being installed upside down (rotated 180° around the height direction), as otherwise the groove would be aligned with the groove and the tongue with the tongue of an adjacent textile tool module.

[0010] Advantageously, a clearance or transition fit exists between the male and female connectors in the vertical direction. Using a clearance or transition fit makes it particularly easy to allow vertical movement of the connected textile tool modules. Preferably, a clearance fit exists between the male and female connectors in the vertical direction, which, taking into account manufacturing tolerances, always ensures a minimum clearance of 0.1 mm. This means that, if the dimensional tolerance limits are met, there is always a clearance of at least 0.1 mm in the vertical direction. However, a minimum clearance of at least 0.2 mm in the vertical direction is particularly preferred. The minimum clearance in the vertical direction corresponds to the maximum adjustment range by which the textile tools can move relative to each other in the vertical direction.Advantageously, the male and female connectors interlock without play in the longitudinal direction. There is therefore no gap between the interlocking male and female connectors. It is particularly advantageous if the male and female connectors have an interference fit in the longitudinal direction. This interference fit provides a holding force to keep the male and female connectors in contact. The interference fit is advantageously releasable by hand or arm without tools. In this way, the textile tool modules are detachably connected while remaining movable and adjustable in the vertical direction.Alternatively, there can be longitudinal play between the male and female connectors, allowing the textile tool modules to move relative to each other both vertically and longitudinally. A holding force can then be provided between the male and female connectors, for example using a magnet, to detachably connect them.

[0011] Further advantages arise when the male connector engages the female connector rotatably about an axis of rotation that runs in a depth direction perpendicular to the longitudinal and vertical directions. Preferably, the rotatability or angle of rotation is limited by a stop. Because the connectors are rotatable relative to each other, even better vertical alignment of the textile tool modules is achieved. Furthermore, this method also makes it easier to compensate for angular errors between the associated textile tool modules during assembly of the module assembly arrangement.

[0012] Advantageously, the female connector is a recess. The recess is shaped so that the projection of the first connector can engage in it. A recess in a module body is very easy to manufacture. Therefore, a textile tool module with such a recess is very inexpensive to produce.

[0013] It is particularly advantageous if the female connector is formed by at least two projections arranged in such a way that they can engage the male connector. The two projections can, for example, have a crescent- or crescent-shaped cross-section and be arranged so that their concave sides face each other, forming a cavity between the concave sides in which the male connector can be received and enclosed by the two projections of the female connector. Textile tool modules are standard components manufactured in large quantities and are therefore highly optimized. They typically contain very little material that can be omitted. Subsequently introducing recesses into the textile tool modules or the module bodies is therefore not always possible.In this case, it can be simpler and more cost-effective to manufacture the female connector from a combination of several projections with the simplest possible shape. In a preferred embodiment, the female connector is formed by at least three projections. The three projections can then, for example, have a circular cross-sectional area and be arranged such that the centers of these circular cross-sections are arranged in a triangle with respect to each other. This embodiment is particularly advantageous because projections with a circular cross-section are easy to manufacture and, in addition, rotation between the male and female connectors can be ensured.

[0014] Advantageously, the at least two textile tool modules comprise at least one male connector and at least one female connector. The at least two textile tool modules can then preferably be directly connected to one another via the male and female connectors. Preferably, the male and female connectors are integral parts of the module bodies of the textile tool modules. The module assembly arrangement can then be manufactured particularly easily and cost-effectively because the contour of the connectors only needs to be maintained in the mold that is already required for manufacturing the textile tool modules in order to obtain the textile tool modules for a module assembly arrangement according to the invention.

[0015] It is particularly advantageous if the module assembly includes a connector through which the at least two textile tool modules are joined, the connector comprising at least one male and / or at least one female connector. Using a special connector reduces the need for modifications to the textile tool modules of the module assembly. Since textile tool modules offer limited design space, a module assembly with a connector is simpler and more cost-effective to implement. It is especially advantageous if the textile tool modules comprise only male connectors and the connector comprises only female connectors. This eliminates the need to remove material from the textile tool modules to, for example, create a recess for the female connector.The connecting piece can be removed after the textile tool modules have been attached to a textile machine. This way, it takes up no space during operation of the textile machine and does not interfere with its operation.

[0016] Further advantages arise when the module bodies of two adjacent textile tool modules each comprise at least one male connector, with these male connectors of the adjacent textile tool modules engaging together in a single female connector of the connector. The module assembly arrangement can thus be manufactured particularly cost-effectively, because a connector with only one corresponding female connector is required to join two connectors of different textile tool modules. Because the male connectors of adjacent textile tools engage together with a corresponding female connector of the connector, and thus two textile tool modules are joined together at only one connection point, this embodiment is also particularly quick and cost-effective to manufacture.Advantageously, the male connecting elements of the textile tool modules and the female connecting element of the connector are projections with a substantially rectangular cross-section. The two projections of the textile tool modules together have an equal or greater longitudinal extent than the recess in the connector. In this way, a transitional or press fit exists between the connecting elements in the longitudinal direction. In the vertical direction, however, the extent of the recess is preferably greater than the vertical extent of the projections, so that the textile tool modules can be displaced or aligned vertically with their projections in the recess.

[0017] Further advantages arise if the at least two textile tool modules, or their module bodies, each include a screw bearing surface and the connecting piece has at least one recess corresponding to the screw bearing surface. This recess is arranged and shaped such that a screw can be screwed into the screw bearing surface with its screw head without colliding with the connecting piece. The connecting piece does not need to be detached from the textile tool module or its module body for this purpose. The screw connection can therefore be made with the connection between the connecting piece and the textile tool module already in place. This simplifies the assembly of the textile tool modules on a textile machine.The textile tool modules are pre-positioned by the connector during assembly as soon as the first module of the assembly is mounted on a textile machine. This frees up the operator's hands to screw in the remaining modules. This reduces assembly and setup time. The connector can advantageously have more than one recess corresponding to the screw bearing surface, for example, two or three. The corresponding recess can advantageously have a concave contour, preferably adapted to the contour of the screw bearing surface. The concave contour can be arc-shaped or semicircular.

[0018] A method according to the invention for mounting the above-described module mounting arrangement on a bar comprises the following method steps: Positioning the module assembly on the bar, aligning a first textile tool module of the module assembly in the vertical direction, attaching the first textile tool module of the module assembly to the bar, aligning a second textile tool module of the module assembly in the vertical direction after the first textile tool module has been attached to the bar, attaching the second textile tool module to the bar after aligning the second textile tool module.

[0019] In the first step of the process, the module assembly is advantageously placed on a surface of the bar that points in the depth direction (surface normal points in the depth direction) – the bar contact surface. The surfaces of a textile tool module that are in contact with a bar for a textile machine to hold the textile tool module to the bar are the module contact surfaces. The module contact surfaces advantageously point in the depth direction. The vertical alignment of the textile tool module is advantageously achieved by at least one stop of the textile tool module, which is positioned on an edge of the bar in the vertical direction. However, vertical alignment can also be performed manually without the use of tools. This requires a technician with considerable experience and a longer assembly time to ensure precise alignment.To attach a textile tool module to a bar, the module can be screwed to the bar, for example. Alternatively, it can be clamped or clamped to the bar using other clamping devices. Another option, or additionally, is to bond the module to the bar in a way that allows for detachable adhesion. For this purpose, an adhesive can be used that loses its adhesive strength at high temperatures exceeding the operating temperature of a textile tool module. Such an adhesive could be, for example, a thermoplastic adhesive. In the method described above, the first and second textile tool modules are mounted together in a module assembly on the bar of the textile machine. This reduces the assembly effort and time. The first and second textile modules can then be aligned vertically independently of each other.This allows all textile tool modules to be individually and precisely aligned, and manufacturing tolerances to be individually compensated. The alignment of the textile tool modules in the vertical direction and their subsequent fastening are therefore carried out sequentially (one textile tool module after the other) and not simultaneously, as would be the case, for example, with module assembly arrangements with several textile tool modules that are detachably glued together.

[0020] Further advantages arise if the module assembly includes a connecting piece that is removed after the first and second textile tool modules have been attached to the bar. Since the connecting piece is detachably attached to the textile tool modules, there is a risk that it could unintentionally detach during operation of the textile machine. To prevent this, the connecting piece can be removed from the module assembly or the textile machine after the textile tool modules have been attached. Therefore, the connecting piece is preferably designed in such a way that it does not perform any function required for the operation of the textile machine.

[0021] Further advantages arise when an additional textile tool module is mounted on the bar after the textile tool modules of the modular assembly have been installed. This additional textile tool module is detachably connected to a textile tool module of the modular assembly, at least temporarily during its installation, in such a way that it is held in its target position and can be moved within a certain adjustment range in the vertical direction. The additional textile tool module is pre-positioned by its connection to a previously mounted textile tool module on the bar and can then be fine-tuned vertically. This pre-positioning of the additional textile tool module significantly simplifies installation and reduces the effort required for aligning the textile tool module.The connection between the additional textile tool module and the previously mounted textile tool module can be made in the same way as described above for the textile tool modules of the module assembly arrangement. The connection can be made, for example, using a connector. Particularly good pre-positioning of the additional textile tool module can be achieved with interlocking male and female connectors.

Figure 7 Fig. 8 shows a suitable connecting piece (5) to the textile tool modules (2) of the third embodiment.

Figure 9 shows a suitable connecting piece (5) to the textile tool modules (2) of the fourth embodiment.

[0022] The Figure 1 Figure 7 shows a bar 7 of a textile machine and a module assembly arrangement 1 mounted on the bar 7. The module assembly arrangement 1 comprises five textile tool modules 2, each equipped with a module body 3. For clarity, the following are shown in the Figure 1Only one textile tool module 2 and its associated features are provided with reference symbols. The textile tool modules 2 from Figure 1 However, they are all identical in construction. Each of the module bodies 3 of the textile tool modules 2 carries textile tools 4, which are arranged side by side or in a row in the longitudinal direction L. In the Figure 1 The textile tools 4 are punch needles for use in warp knitting machines. The textile tool module 2 is also referred to by experts as the punch needle module. Due to the fineness of the textile tools 4 and their close arrangement in the longitudinal direction L, the distances between the individual textile tools 4 are... Figure 1Barely discernible. In the area marked with reference numeral 4, textile tools 4 are arranged lengthwise L at very small intervals. The fine black lines visible in this area each represent an edge of an individual textile tool 4, and the white spaces between these fine black lines correspond to the distance between the respective textile tools 4. The textile tool modules 2 are detachably connected to their adjacent textile tool modules 2 by connecting pieces 5. This connection allows the textile tool modules 2 to be handled together during assembly.In the present case, the textile tool modules 2, with their module mounting surfaces 14 pointing in the depth direction T, were jointly positioned on the bar mounting surface 13 of the bar 7, individually aligned in the height direction H on the edge 15 of the bar 7, and fastened to the bar 7 by individually screwing them against the bar mounting surface 13 with screws 11. The edge 15 of the bar 7 has a surface normal that points in the height direction H. The alignment on the edge 15 can be achieved by stops on the textile tool modules 4, such as those already well known to those skilled in the art, for example, from commercially available needle-punch modules. Since the connection between the connecting piece 5 and the textile tool modules 2 of the module assembly arrangement 1 is not visible in the assembled state, the features of the connecting piece 5 and the textile tool modules 2 relevant for the connection are described below using individual part drawings. Figures 2 and 3 depicted.

[0023] The Figure 2 shows two textile tool modules 2 of which are already in Figure 1 first embodiment of the module mounting arrangement 1 shown. Figure 3 The corresponding connecting piece 5 of this first embodiment is shown. While in the Figure 1 The assembled state of the module assembly arrangement 1 is shown, in which the textile tool modules 2 are connected to each other by several connecting pieces 5, show the Figures 2 and 3 The textile tool modules 2 and the associated connecting piece 5 as individual parts in an unconnected state. The connecting piece 5 is in the Figure 3 compared to the assembled state Figure 1 The figure is shown rotated 180 degrees about the longitudinal direction L to show the male connecting elements 106 of the connecting piece 5, which, according to this embodiment, are projections used for connecting the textile tool modules 2. That is to say, to connect the textile tool modules 2 made of Figure 2 the connecting piece 5 from Figure 3 first rotated 180 degrees around the longitudinal direction L and then connected to the male connecting elements 106 in the two in Figure 2 The textile tool modules 2 are aligned with the female connecting elements 206 marked with reference symbols. The male connecting elements 106 and the female connecting elements 206 interlock to form a detachable connection between the textile tool modules 2. In this way, the textile tool modules 2 and the connecting piece 5 form a module assembly arrangement 1, as shown in Figure 1The female connecting elements 206 of the textile tool modules 2 are recesses in the module bodies 3, each of which engages one of the male connecting elements 106. In the assembled state, the male connecting elements 106 are rotatable about the axes of rotation 12 extending in the depth direction T, so that the textile tool modules 2 can be moved or aligned relative to each other in the height direction H by rotating them about the axes of rotation 12. This allows for individual fine adjustment of each textile tool module 2 in the height direction H when the module mounting device 1 is mounted on a bar 7 of a textile machine. The textile tool modules 2 can also be held movable relative to each other in the height direction H and the longitudinal direction L by corresponding dimensional tolerances for the dimensions of the male and female connecting elements 106, 206.For this purpose, an interference fit can be selected in the longitudinal direction L to provide a clamping force acting in the longitudinal direction L. In the vertical direction H, a clearance fit or a transition fit can be selected instead, for example. To mount the module mounting arrangement 1 on a bar 7 (as in . Fig. 1 To further simplify the process (as shown), the textile tool modules 2 each have a screw hole 10 that completely penetrates the respective module body 3 of the textile tools 2 in the depth direction T and is open on one side in the height direction H. Due to the one-sided opening of the screw hole 10 in the height direction H, the screws 11 only need to be loosened, but not completely unscrewed from the bar 7, in order to mount or dismount the textile tool modules 2. However, the technical teaching of the present invention can also be implemented with textile tool modules 2 whose screw hole 10 is a conventional through hole without the [missing information]. Figure 2The one-sided opening shown is a feature of the design. To ensure the best possible fastening of the textile tool modules 2 by the screws 11, the module bodies 3 have screw bearing surfaces 8 that extend around the screw hole 10 and meet increased requirements for surface flatness. The connecting piece 5 has corresponding recesses 9 that are adapted to the contour of the screw bearing surface 8 and the head of the screws 11 in such a way that the textile tool modules 2 can be screwed together with the screws 11 even when the connecting pieces 5 are engaged with the textile tool modules 2. This means that the screws 11 can be installed and rotated in the screw hole 10 even when the connecting piece 5 is engaged with the textile tool modules 2. The connecting piece 5 therefore does not block the screws 11.

[0024] A second embodiment of a module assembly arrangement 1 is described in the Figures 4 and 5 shown. Figure 4 Figure 1 shows a perspective view of the module assembly arrangement 1 with two textile tool modules 2. The basic structure of the textile tool modules 2 with textile tools 4, module bodies 3, screw hole 10 and screw bearing surface 8 is the same as that of the textile tool modules 2. Fig. 2 However, the shape and arrangement of the male fasteners 106 and the female fasteners 206 differ in this embodiment in that they are designed as a tongue-and-groove connection 6. How the male fastener 106 and the female fastener 206 interlock as a tongue-and-groove connection 6 is shown in the figure below. Fig. 5Section AA is shown. The textile tool modules 2 each have a male connector 106 and a female connector 206, which are arranged on the module body sides 18 that define the longitudinal boundaries of the module bodies 3 L. The male connector 106 of the first textile tool module 2 engages longitudinally in the female connector 206 of the adjacent textile tool module 2 to create a connection between the two textile tool modules 2. The female connector 206 thus surrounds the male connector 106. In this way, unlike the connection shown in the Figures 1 to 3In the illustrated embodiment, a connecting piece 5 between the textile tool modules 2 is omitted. The male connecting element 106 of the tongue-and-groove connection 6 is an elongated projection, also known to those skilled in the art as a tongue. The female connecting element 206 of a tongue-and-groove connection is a groove-shaped or elongated recess suitable for engaging the elongated projection. The male and female connecting elements 106 and 206 have a cross-section that is constant along the vertical direction H. In this way, the tongue-and-groove connection 6 allows the textile tool modules 2 to be movable relative to each other in the vertical direction in order to adjust their desired position in the module assembly arrangement 1.In addition, the male connecting element 106 and the female connecting element 206 of the tongue-and-groove connection 6 are also displaceable relative to each other in the longitudinal direction L, so that the textile tool modules 2 are also adjustable relative to each other in the longitudinal direction L. The textile tool modules 2 can thus be adjusted during the assembly of the module assembly arrangement 1 on a bar 7 (in the . Figs. 4 and 5 (not shown) can be adjusted even more precisely. In the present embodiment, the possible adjustment range is not limited in the vertical direction H and the longitudinal direction L. This further simplifies the adjustment of the textile tool modules 2 on a bar 7.

[0025] The Figure 6 and 8 Two textile tool modules 2 each show a third and a fourth alternative embodiment of the module assembly arrangement 1, respectively. Figure 7 and 9The respective connecting pieces 5 are shown. The third and fourth embodiments differ from the first embodiment, which is shown in the, only in their male and female connecting means 106, 206 or their arrangement. Figures 2 and 3 As shown and described above. Since the male and female connecting elements 106, 206 are not visible in the assembled state of the module assembly arrangement 1, the representation differs from the Figure 1 The view shown of the module mounting arrangement 1 of the first embodiment does not differ for the third and fourth embodiments. Figure 1 The representations of Figure 1 The same applies to the third and fourth embodiments.

[0026] The following are the differences between the in the Figures 6 and 7The third embodiment and the first embodiment are described below. In the third embodiment, the male connecting elements 106 are assigned to the module bodies 3 of the textile tools 2 and not to the connecting piece 5 as in the first embodiment. Correspondingly, the female connecting element 206 is assigned to the connecting piece 5. The assignment of the male and female connecting elements 106, 206 to the textile tool modules 2 and the connecting piece 5 is therefore reversed in the third embodiment compared to the first embodiment. This clarifies that the present technical teaching can be implemented independently of this assignment. Additionally, the female connecting elements 206 of the third embodiment also differ from those of the first embodiment.The female connectors 206 are not simple recesses, but are formed by three cylindrical projections on the surface of the connector 5, the three cylindrical projections being arranged relative to each other such that their central axes form the vertices of an imaginary triangle 19. These imaginary triangles 19 of the female connectors 206 are in the . Figure 7 indicated by dashed lines. The cylindrical projections within these triangles 19 each enclose a space 20 into which one of the male connecting elements 106 fits. In the assembled state of the module assembly 1, which is in Figure 1As shown, each of the male connecting elements 106 engages in one of the gaps 20. In this way, the cylindrical projections of the female connecting elements 206 can engage the male connecting elements 106 in the assembled state of the module assembly arrangement 1. In this third embodiment, the adjustment range between the textile tool modules 2 is limited by the size of the gaps 20.

[0027] The following are the differences between the in the Figures 8 and 9 fourth embodiment shown and the first embodiment from the Figures 2 and 3 described. The assignment of the male fasteners 106 and the female fasteners 206 to the textile tool modules 2 (see Fig. 8 ) and the connecting piece 5 (see Fig. 9The arrangement of the male connectors 106 is reversed compared to the first embodiment. This means that the male connectors 106 are assigned to the textile tool modules 2, and the female connectors 206 are assigned to the connector 5. The male connectors 106 of the fourth embodiment differ from those of the first embodiment in that they are cuboid projections. The connector 5 comprises a single female connector 206, which is a cuboid recess of such a large size that this single female connector 206 can engage two male connectors 106. This means that in the assembled state of the module assembly arrangement 1, as shown in Figure 1As shown, two male connecting elements 106, each assigned to one of the two adjacent textile tool modules 2, engage together in the single female connecting element 206 of the connector 5 to connect the adjacent textile tool modules 2 to each other. In order to ensure the alignability of the textile tool modules 2 in the vertical direction H in this embodiment, the extension length of the male connecting elements 106 in the vertical direction H – the projection length 17 – is smaller than the extension length of the female connecting element 206 in the vertical direction H – the recess length 16 – whereby a difference of less than 1 mm is sufficient to provide a sufficiently large adjustment range for the adjustment of the textile tool modules 2.For individual fine-tuning of the textile tool modules 2, the male connecting elements 106 can be moved relative to each other in the vertical direction H within the recess of the female connecting element 206.
