The task is to create a method and a universal system for manufacturing containers based on spiral tubes, which method can be used to manufacture all possible types of spiral tubes economically and in an energy-optimised manner within a complex system, requires little space for installation of the system, and operates fully automatically. The method according to the invention is applicable to a wide variety of web materials. Said web materials are supplied from a feeding web supply station (1) with narrow rolls (1.1) mounted therein which are loaded with the web materials that are to be processed. The winding station (3) consists of the winding mandrel (3.1) and a winding belt (3.3) that presses the webs onto the winding mandrel (3.1). The winding mandrel (3.1) is driven by means of a winding mandrel drive (3.2). The individual pre-glued narrow roll webs (1.2) are wound obliquely, overlapping and under uniform web tension onto the winding mandrel (3.1).

In order to ensure that the endless spiral tube (3.4) can be cut precisely at the intended points with uniform cutting edges that do not require reworking, it is necessary to synchronise the linear motion of the endless spiral tube (3.4), the labelling station (4), and the cutting station (5) in such a way that the spiral tubes (9) can be cut into individual tubes in the cutting station (5) exactly to the size of the applied label (4.3). For monitoring purposes, it is advisable to distribute one position-detection sensor (8) or a plurality of position-detection sensors (8) here.

Description

[0001] Process and plant for the production of containers based on spiral sleeves

[0002] The invention relates to a method and a plant for producing containers based on spiral cores for various types of spiral cores, which are wound and produced from paper webs according to the preambles of the independent claims.

[0003] Generic cores made of paper or cardboard webs, which are produced by winding flat materials onto a winding mandrel, have been known for a long time. A fundamental distinction is made between two different types: those that are wound parallel, meaning that the paper is wound onto a mandrel perpendicular to a winding axis, with the individual layers glued together; and those paper cores in which the paper strip(s) are wound onto a winding mandrel at an angle to the winding axis. The angled winding creates a core of any length, known as a spiral core. Due to these advantages, such as greater rigidity and faster production speed, these endless spiral cores have become established in production.The production speed of the endless spiral core is determined by the pitch of the individual, diagonally wound paper strips and the resulting constant forward thrust. Therefore, a single winding system can produce considerably more spiral tube per unit of time. The endless spiral core produced in this way is then cut to length in a cutting system itself, creating individual spiral cores of a specific length, which are then stored in a buffer. These individual cores are then picked up again in a separate system and coated with a parallel label in a separate labeling machine. The labeled individual core is then cut to the required final size, which generates a considerable amount of waste. Furthermore, the cost of producing containers based on spiral cores is relatively high.

[0004] As an example for the production of a stable spiral core, the technical solution according to US 3,194,275 A1 should be mentioned here. This paper spiral core consists of a plurality of individual fibrous paper strips, which are spirally overlapped and formed into a stable spiral core using adhesive in the overlapping area. These paper strips are wound at a winding angle of only approximately 15-25 degrees, i.e., with a relatively low pitch angle, which is overall limiting and disadvantageous. DE 2012 109 279 A1 describes a method and device for producing cores, in which strip-shaped web material is continuously applied with adhesive in the overlapping area using a suitable application head. It is also possible to apply two different adhesives in order to achieve better bonding of the paper webs.To accelerate bonding, it is also possible to use heat-applied adhesives, which then develop their full adhesive strength relatively quickly upon cooling. The result is an endless spiral sleeve, which must then be cut to a specified length.

[0005] DE 2 649 658 A1 describes a can made of spirally arranged fiber material for food products and a method for its production with a diagonally running label. This label has a collar cut, whereby the fiber material body of the can is not cut, and the can can be reliably opened without the label tearing irregularly. A dividing line is created during can production, running from one end of the can to the other end, which is covered by the label and thus secured against unattended opening. By peeling the label off at an angle by hand, the actual dividing line opens, allowing the can contents to be easily removed. This solution is only suitable for a few applications.

[0006] EP 1 0557 733 A1 describes a method for producing multi-layer tubular containers with a window for viewing the product contained therein. An inner lining layer is first wound on a mandrel to create a tubular shape. The lining layer is formed from a low-opacity polymer material. After winding, the lining layer is further advanced on a forming mandrel, and then a bias-wound spiral sleeve layer is applied. A reference mark is printed on a label layer and used to cut openings from the label layer at predetermined locations along the length of the can.When the actual spiral sleeve is wound around the previously wound lining layer on the mandrel and the label layer is subsequently wound onto the previously wound spiral sleeve on the same mandrel, the openings in the label layer are aligned with the openings in the spiral sleeve to create a tubular shape with a viewing window through the corresponding openings and onto the lining layer. DE 27 25 116 A1 describes a method and device for spiral labeling spiral sleeves, wherein a continuous label strip is also wound at an angle onto a helically wound spiral tube.To achieve the required alignment between the individual label sections and the cut points created by a cutting device, the conveying speed of the rotating spiral tube is determined using a photoelectric scan of markings applied at specific intervals on the label strip. By comparing the drive speed of the label strip with the drive speed of the cutting device, the relative speeds are automatically corrected if any deviations occur.The correction value determined from the comparison of the drive speed of the cutting unit with the conveying speed of the label strip is used to change the speed of the winding belt by taking a positive or negative additional movement for the drive of the winding belt from the drive of the cutting unit, which is driven at an unchanged speed, via an electromagnetic clutch controlled by the photoelectric scanning of the label strip and applying it.

[0007] DE 2 226 881 A1 further claims a device and method for producing spirally wound cores from one or more material webs wound around a centrally arranged mandrel. A core with a printed image is applied to this mandrel, which is then divided into separate lengths. The diameter of this mandrel is variable, i.e., it is adjustable, allowing the printed image to be precisely positioned relative to the cut-to-length spiral core during cutting. This device is suitable for various can cross-sections.

[0008] The object of the invention is to create a method and a universal system for producing containers based on spiral cores, which can produce all possible types of spiral cores within a complex system in an economical and energy-optimized manner, requires little space and room for installation, operates fully automatically, and can, if required, introduce any desired, freely formable windows into the spiral core wall of the container. The object of the invention is achieved by the features of the first and second patent claims. Further advantageous embodiments of the invention are described in the dependent claims. The method according to the invention can be used for producing containers based on spiral cores from a wide variety of web materials, such as paper, cardboard, and / or film webs. These are fed from a feeding web supply station 1 with narrow rolls 1 suspended therein.1, which are each loaded with the web materials currently being processed. The web materials are held under tension by arranged web brakes 1.3 in order to achieve the most even feed possible of the individual narrow roller conveyors 1.2 to a winding station 3. The winding station 3 is actually constructed as is known and consists of the winding mandrel.

[0009] 3.1 and a winding belt 3.3 that presses the webs onto the winding mandrel 3.1. However, it differs from the known winding machines in that the winding mandrel 3.1 rotates in a novel manner at a specific speed. To achieve this, a winding mandrel drive 3.2 is arranged at the free end of the winding mandrel 3.1. The individual narrow roller conveyors 1.2 are wound onto the winding mandrel 3.1, as is known, diagonally overlapping and with uniform web tension. Beforehand, the individual narrow roller conveyors 1.2 are pulled out of the suspended narrow rollers.

[0010] 1.1 is glued in the later overlapping areas using individual gluing units 2.1 before the glued narrow roller conveyors 1.2 are fed to the rotating winding mandrel 3.1 in an overlapping manner at a defined, predefined angle. The gluing of the individual glued narrow roller conveyors 1.2 to form a glued endless spiral tube 3.4 is ensured, as is known, by pressing using a diagonally running winding belt 3.3, which moves the endless spiral tube 3.4 further in a linear manner. Each individual material web fed in is additionally electronically monitored and controlled by means of arranged devices so that the most precise and uniform web tension possible can be generated by the web brakes 1.3. The rotation is achieved by driving the winding mandrel 3.1, in particular by means of a controlled servo drive, so that it rotates at a precisely defined, uniform speed.This has the advantage of reliably stabilizing the incoming base web and preventing the endless spiral tube 3.4 from floating on the driven winding mandrel 3.1. Furthermore, any change in the overlap of the overlapping web materials during winding is avoided. Furthermore, a continuous linear movement of the endless spiral tube 3.4 on the winding mandrel 3.1 is generated. During the linear movement, glued labels 4.3 are applied in a labeling station 4 integrated into the system using one or more sheet feeders 4.2 of a defined size. These can either be glued directly in the labeling station 4 using one or more roller gluing stations 4.1 before feeding, or suitable self-adhesive labels can be applied. The labeling station 4 can be designed so that only one label 4.3 is applied before the endless spiral tube 3.4 reaches a cutting station 5, which is also integrated into the system, is cut, and a spiral sleeve 9 is created. However, it is also possible to apply several labels 4.3 simultaneously to the endless spiral tube 3.4 next to one another in accordance with the planned sleeve length required in the future, before the endless spiral tube 3.4 is then simultaneously cut into individual spiral sleeves 9 in the cutting station 5, according to the number of successively applied labels 4.3, using multiple cutting devices 5.1. In order to ensure that the endless spiral tube 3.4 can be cut precisely at the intended locations with uniform cutting edges that do not require rework, it is necessary to synchronize the linear movement of both the endless spiral tube 3.4 and the labeling station 4, as well as the cutting station 5, so that the spiral sleeves 9 are cut to exactly the size of the applied label 4.3 into individual cores of defined length in the cutting station 5. This is only possible through the interaction of the controlled rotary movement of the winding mandrel 3.1 and the precisely synchronized movements of all system components. For monitoring purposes, it is advisable to distribute one or more position detection sensors 8 at each location.

[0011] It is advantageous in the universal system for producing containers based on spiral sleeves 9 if a forming station 7 for forming other cross-sections is arranged at a suitable location in the system as a further work station. This is possible, for example, if the cross-section of the winding mandrel 3.1 changes, so that during the axial movement of the endless spiral tube 3.4 the initially round cross-section of the winding mandrel 3.1 continuously changes into a rectangular or square cross-section, wherein the base body, i.e. the not yet hardened endless spiral tube 3.4, is deformed in such a way that, for example, a rectangular or square cross-section of the spiral sleeve 9 with rounded edges is created at the end of the winding mandrel 3.1. In a further embodiment of the universal system for producing containers based on spiral sleeves, a window cutting station 6 is additionally integrated into the system.The window cutting station 6 is arranged at a defined position opposite the winding mandrel 3.1. At the end of the winding mandrel 3.1, one or more openings 10 corresponding to the window cutting station 6 are formed. Either a laser cutting device 6.1 or a water jet cutting device 6.2 engages at the open point(s). These execute a controlled, predeterminable cutting path and cut windows in the container shell of the endless spiral tube 3.4 in the desired, arbitrarily formed, and precisely specified shape. Depending on the spiral tube size or

[0012] Depending on the spiral sleeve diameter, the cutting jets act either from the inside out or from the outside in. The endless spiral tube 3. 4 is then cut to the exact length, creating individual sleeves 9 with windows.

[0013] In a further embodiment of the universal system for producing containers based on spiral sleeves 9, a window cutting station 6 is integrated directly downstream of the cutting station 5, wherein the spiral sleeves 9 already cut to length by the cutting station 5 can either be picked up directly or temporarily stored before the window is inserted. At least one laser cutting device 6.1 or at least one water jet cutting device 6.2 is configured in the window cutting station 6, which can cut one or more windows of any shape into the cut-to-length spiral sleeve (9). Since a large number of spiral sleeves 9 are generally produced from the endless spiral tube 3.4 in a relatively short period of time using a multiple cutting station, it is expedient to configure the window cutting device 6 in such a way that it accommodates several receiving devices with several laser cutting devices 6.1 or more laser cutting devices 6.2 are arranged, which simultaneously produce the desired windows for each spiral sleeve 9 in parallel, ie, this is a multiple window cutting station, where several individual sleeves 9 can be picked up, clamped, and processed in parallel. Here, too, it is possible to use either the laser cutting device 6.1 or the water jet cutting device 6.2, depending on the container type, container size, or

[0014] Container diameter, material composition and material properties to act either from the inside out or from the outside in. In a system designed according to claim 5, a method for producing containers on the basis of spiral sleeves 6 is implemented, in which a previously cut individual sleeve 9 is received and centered on one side, separately clamped and positioned, then a laser cutting device 6.1 is brought into engagement with at least one laser working head 6.1.1. An absorption device 6.1.1 is introduced inside the individual sleeve 9 and an additional suction device is arranged. The cut individual sleeve 9 is moved linearly in a defined manner and rotated at the same time, so that one or more windows can be cut out and formed in the cut individual sleeve 9.To avoid contamination, both the cut-out window parts and the abrasion generated by the laser beam are simultaneously vacuumed away during the actual cutting process.

[0015] The advantage of this process and of the universal system for producing containers based on spiral sleeves is that it can produce all possible types of spiral sleeves 9, i.e. individual sleeves of any selectable size and length, economically and with optimized energy consumption using a single complex system. In addition, such a universal system requires very little space to set up and the overall space requirement is minimized. It can also operate fully automatically and, unlike other systems, can also produce any number of freely formable windows in the spiral sleeve wall if required. This makes it possible to directly view the contents of the container, which will later be completed with a lid and base, from the outside if the window is sealed with transparent material. Such containers with windows are otherwise only produced using specially designed and structurally complex machines.

[0016] The invention will be explained in more detail below with reference to Figures 1 to 4. Fig. 1 shows schematically the structure of a system according to the invention without a downstream window cutting station 6

[0017] Fig. 2 shows a schematic view of the endless spiral tube 3.4 with a directly coupled downstream window cutting station 6. Fig. 3 shows a preferred embodiment of a downstream window cutting station 6 with a single laser cutting device 6.1. Fig. 4 shows a downstream separate window cutting station 6 with a single laser cutting device 6.1. Figure 1 shows a schematic structure of a system according to the invention for producing containers on the basis of spiral sleeves without a directly downstream window cutting station 6 coupled to the winding mandrel 3.1. In principle, two different options for the spatial arrangement and setup of the web supply station 1 with the gluing station 2 are feasible. These two stations can be set up at ground level at an angle to the winding axis 3.5 and can be moved linearly in the direction of the winding axis 3.5.Or, to save space, the web supply station 1 and the gluing station 2 are arranged upwards towards a correspondingly high hall ceiling, which allows the ground-level space requirement to be significantly reduced in a simple manner. The web supply station 1, together with the downstream gluing station 2, is set up and arranged at a specific angle in relation to the winding axis 3.5. If required, both can be moved linearly along the winding axis 3.5 and can also be pivoted in relation to the winding axis 3.5. This area, in which the two stations can be pivoted, moves at an angle of between 110 and 160 degrees in relation to the winding axis 3.5 (see position 1 '). This has the advantage that the individual narrow roller conveyors 1.2 can run onto the winding mandrel 3 at different gradients, as required.1 can be wound up in an overlapping, diagonal spiral manner. The narrow rolls 1.2 are stocked and stored in the web supply station 1. For monitoring purposes, a narrow roll monitoring electronics unit 1.4 is arranged at a suitable location in the web supply station 1 in order to be able to recognize and detect, in particular, a web break in the web material used or the end of a narrow roller conveyor 1.2. In order to enable the narrow roller conveyors 1.3 to be unwound and fed to the winding station 3 as evenly as possible, conventional spring-loaded web brakes 1.3 or compressed air-operated web brakes 1.3 are arranged in the web supply station 1 and act on the formwork roller conveyors 1.2 in such a way that they are subjected to a constant tensile stress and can run evenly with a precisely defined tensile stress onto the winding mandrel. In the downstream gluing station 2 there are usually 1 for each of the supplied narrow roller conveyors.Two individual gluing units 2.1 are arranged so that each narrow roller conveyor 1.2 can be evenly applied with glue. Along the winding axis 3.5, the other processing stations of the overall system according to the invention are arranged linearly and centrally relative to it, one after the other. The winding mandrel 3.1 is driven separately by a winding mandrel drive 3.2, which is usually a servo motor, and is controlled in such a way that, thanks to this additional rotation, the endless spiral tube 3.4 produced on the winding mandrel 3.1 also rotates as evenly as possible, allowing the entire winding process to proceed with great consistency. The winding mandrel 3.1 can be driven either directly via a winding mandrel drive 3.2 flanged onto the winding axis 3.5 or indirectly via a winding mandrel drive 3.2 arranged offset from the winding axis 3.5 and suitably connected, for example, via a drive belt or a chain drive. The incoming formwork roller conveyors 1.2 are wound spirally over one another at a specific angle and driven linearly forward by a winding belt 3.3 that wraps around the resulting endless spiral tube 3.4. Due to its pre-tension, the wrapping belt 3.3 rests on the surface of the casing of the endless spiral tube 3.4 with a specific contact pressure, drives it, and in this way generates a defined feed of the endless spiral tube 3.4. The contact pressure glues the individually fed, glued narrow roller conveyors E2 together to form a solid, stable tube assembly. The curing speed of the bond can be easily adjusted by selecting a suitable adhesive. By precisely coordinating the speed of the resting winding belt 3.3 and the additional winding mandrel drive 3.2, the endless spiral tube can be produced very uniformly with a smooth surface, without any offset between the webs, and with a very uniform pitch of the individual material webs. Furthermore, a highly constant feed motion of the resulting endless spiral tube 3.4 is generated, which is of fundamental importance for the further, possibly intermediate, forming, labeling, cutting, and, if coupled, window cutting for the production of such spiral sleeves 9.

[0018] The resulting endless spiral tube 3.4 moves linearly at a constant feed rate along the winding axis 3.5 on the winding mandrel 3.1 and thus reaches the labeling station 4. First, a roller gluing station 4.1 is usually engaged in this labeling station 4 so that the endless spiral tube 3.4 is completely coated with glue. The glue can also be applied by other means, for example by spraying. The label 4.3 is applied and rolled up by a sheet feeder 4.2 arranged downstream and moved linearly at the same speed as the endless spiral tube 3.4. This is necessary because the winding mandrel 3.1 rotates at the same speed and continues to move linearly. A cutting station 5 consisting of a cutting device 5.1 is arranged downstream of the labeling station 4. This contains a knife holder 5.3 with at least one circular knife 5.2 and at least one counter pressure roller 5.4, which cut the spiral core 9 to length. To ensure that the cutting takes place exactly at the intended point, the circular knife 5.2 or the entire cutting station 5 is moved in such a way that the cutting process can take place at a precisely defined point in the dividing line between two consecutive labels 4.3. This is only possible because the harmonization of all movements with very high precision can be achieved with this system. The system according to the invention reduces the left and right waste rings for each cut-to-length individual core 9, which were created in previous systems, to a maximum of one waste ring per production cycle. This brings about a considerable reduction in waste during spiral core production. Another prerequisite is optimal coordination of the material widths of the individual narrow roller conveyors 1.2.

[0019] Figure 2 shows a schematic view of an embodiment of the system according to the invention for forming the endless spiral tube 3.4 with the distribution of the individual processing stations along the winding axis 3.5. At the left end is the winding mandrel drive 3.2, which drives the winding mandrel 3.1. Next is the winding station 3. In this station runs the winding belt 3.3, which creates the endless spiral tube 3.4 from the several individual glued narrow roller conveyors 1.2. Next is a forming station 7, which brings the endless spiral tube 3.4 into a defined shape. This forming station 7 can optionally be omitted. Next is the labeling station 4, which is moved uniformly at the same speed as the endless spiral tube 3.4 and applies the labels 4.3. The cutting station 5 arranged downstream is also moved linearly along the winding axis 3.5 at the same speed.On the right side, a directly connected downstream window cutting station 6 is connected. This window cutting station 6 is aligned or nearly aligned with the winding axis 3.5 and cuts a window into the endless spiral tube 3.4 before the cutting process for cutting the endless spiral tube 3.4 to length begins. The window cutting station 6 is also moved along accordingly and performs a precisely defined movement for cutting the window. Only after a window has been inserted is the circular knife 5.2 engaged and an individual tube 9 cut to length.

[0020] Figure 3 shows an external laser cutting device 6.1. However, a water jet device 6.2 can just as easily be designed and arranged in its place. An absorption sleeve 20 is inserted into the inside of the cut-to-length spiral sleeve 15,6, which is initially picked up and clamped by a movable sleeve holder 18. This absorption sleeve 20 is arranged on an additional centering mandrel so that the spiral sleeve 15 is also centered and clamped from this side upon insertion. This absorption sleeve 20 is moved by a movement unit with a centering mandrel 16 arranged thereon and is moved into the interior of the spiral sleeve 15,6 and positioned. The spiral sleeve 15 is furthermore deposited, positioned, guided and supported in a defined manner by two guide rails 17 during insertion. A working head 14, in this case a laser head, is then engaged from the outside by a movement unit working head 13.The working head 14 is subjected to a laser beam by the beam source 12, whereby the working head 14 deflects the cutting steel and focuses it precisely onto the surface of the spiral sleeve 15. The beam source 12 and the movement unit of the working head 13 are actuated and guided by a central movement unit 11. Furthermore, a further movement unit 19 is indicated, which moves a gripper (not shown). A suction device is also installed here, which sucks the abrasion generated during the cutting process from the interior of the spiral sleeve, which is tensioned on both sides, through an opening made in the centering mandrel of the movement unit 16. A window cutting device 6, which acts directly at the end of an endless spiral tube 24, i.e. the spiral sleeve 9 to be cut to length projects beyond the end of the winding mandrel 3.1, has a similar construction, except that the sleeve holder 18 is omitted.The movement unit with centering mandrel 16 then moves toward the end of the endless spiral sleeve 3.4 and positions the absorption sleeve 20 inside. The working head 14 is moved, positioned, and engaged. This performs the actual cutting movement, but must also simultaneously take into account and execute the rotational movement of the winding mandrel 3.1 and the linear movement of the endless spiral sleeve 3.4. This then logically requires a structurally precise design of the window cutting device 6 with a CNC control of the working head 14. In another design, either one opening or several openings 10 are arranged directly in the cylinder of the winding mandrel 3.1 itself at the point where the window(s) are to be inserted, whereby tensioning of the endless spiral sleeve 3.4 at the end is not necessary, since the endless spiral tube 3.4 rests directly on the winding mandrel 3.1 and cannot change its position during the cutting process. The working head 14 is moved both linearly and also rotates by a special movement unit. The cutting beam cuts out the window and is prevented from damaging the cylinder jacket of the spiral sleeve 9 on the other side by the absorption sheet 34. If necessary, the absorption sleeve can also be omitted because the inner closed wall of the winding mandrel 3.1 breaks the cutting beam and no damage can occur to the inner surface of the endless spiral tube 3.4, i.e. to the inner surface of the spiral sleeve 9 to be cut to length. Once the window has been cut out, the absorption sheet, if provided, is extended and the finished spiral sleeve 9 is cut to length using a suitable cutting device 5.1. In the simplest case, the cutting device 5.1 consists of a knife holder 5.3 in which a circular knife 5.2, which is pressed against the endless spiral sleeve 3.4 for cutting, so that a clean cut can be achieved. To prevent the endless spiral roller 3.4 from being deformed during the cutting process, at least one rotating counterpressure roller 5.4 is arranged. For positioning, at least one position detection sensor 8 is arranged in order to enable precise cutting to length without offset. In the meantime, the next spiral sleeve 9 is advanced far enough that the window cutting station 6 can be engaged again. The working head 14 is then repositioned, and the cutting process is repeated accordingly.

[0021] Figure 4 shows a separate downstream window cutting station 6 with a single window cutting device. In this exemplary embodiment, which can be used primarily at high production speeds of the system for producing individual sleeves 9, the cut-to-length spiral sleeves 9 are first stored in a buffer before they are picked up again in a single-axis window cutting system 6 or, more preferably, in a multi-axis window cutting system 6 operating in parallel, clamped on both sides, and the windows cut out. Two grid boxes 29 are arranged on a frame 21 as buffers, from which the individual sleeves 9 are removed, cut, and deposited again. The feed to the spiral sleeve holder 35, which is operated by a working device 38, is not shown in the drawing.A beam source 22 is arranged in the frame 21, which beam source 22, via a beam guidance unit 31, applies beams to the working head 32 on the working head movement unit 33. A single spiral sleeve 36, clamped in the spiral sleeve holder 35, is pivoted by 90 degrees by means of a turntable movement unit 37. The centering mandrel 25 is then moved by means of the centering mandrel movement unit 24, and the single spiral sleeve 36 is clamped on both sides. A suitable absorption plate 34 is arranged on the centering mandrel 25, which has an opening for suction, to prevent the cutting beams from striking the inner wall opposite the window to be created and damaging it. After the cutting process, the frame is pivoted again and a new sleeve is clamped, while the machined single spiral sleeve 36 falls over the guide plate into one of the grid boxes 29.Prior to this, the abrasion from the cutting process and the resulting cutting residue are blown out using a suitably positioned compressed air nozzle 39 and collected in the cutout collection container 30. The turntable movement unit 37 is operated by a superstructure movement unit 27. The entire work table can be quickly and easily adjusted, positioned, and moved to various lengths of the individual spiral sleeve 36 using the work table movement unit 26. In this special version of a separate, externally arranged window cutting station 6, a control cabinet with a complex CNC control unit is also arranged, which can be operated and monitored via the control panel 23.

[0022] In principle, it is conceivable to arrange an additional automatic device on or in the frame 21 in this structural design, which device attaches a container base of the future container and fastens it in a suitable manner, e.g. by means of gluing.

[0023] The invention is applicable to the production of containers based on spiral sleeves made of the same or different narrow roller conveyor materials with different cross-sectional diameters and cross-sectional shapes, as well as for many possible types of spiral sleeves.
