    The invention relates to a winding machine and equipped with this winding machine manufacturing plant, as indicated in the claims 1 and 15. A method of operating such a winding machine is described in claim 16.
    Various winding machines are known from the prior art, on which a spindle unit is formed with spool for winding tapes. The spindle unit, in particular the spool of the spindle unit, serves to accommodate a winding tube, to which winding tube a wound-up band is attached. After attaching the tape to be wound on the winding tube, the spindle unit is added together with the winding tube in a rotational movement about the axis of the spindle unit, whereby the wound tape is wound onto the winding tube. In order to distribute the tape evenly on the winding tube, a laying unit is usually arranged on the winding machine, which laterally guides the wound tape during the winding process and thus distributed uniformly over the width of the winding tube. At the end of the winding process, a finished wound coil is obtained on which the strip is wound evenly. As a further step, the endless belt is cut off by a cutting unit, which is held by various mechanisms on the spool, loose tape end and then the finished wound coil by means of a filming device is coated with a film so that the wound tape is no longer independent from the coil can solve. Furthermore, the severed end of the endless belt, which is located in the tape feed unit in the winding machine, held by various mechanisms so that it can be supplied at the start of a new winding operation of an empty winding tube and secured thereto. The removal of the finished wound coil or the transport of a new winding tube takes place by removing the wound coil or by attaching a new winding tube, each in the horizontal direction. Depending on the degree of automation of the winding machine, this change process can be done manually. Furthermore, it is also common that the change process is automated, wherein a manipulation unit is used, which decreases the finished wound coil in the horizontal direction of the spindle unit in the axial direction of the same, an automated Abtransportsystem feeding and further removes an empty winding tube from a storage for winding cores and feeds the spindle unit.
    The embodiments known from the prior art have the disadvantage that due to the horizontal position of the spindle unit the change from fully wound coils to a winding tube to be wrapped must be carried out by a manipulation unit, which manipulation unit increases the space requirement of the winding machine and also a complex one , represents mechanical system, which is error-prone and which manipulation unit is expensive to purchase.
    The present invention has for its object to provide a winding machine, which requires a comparatively less than conventional winding machines space. In addition, but also the cost of complex manipulation units to automate the bobbin change should be reduced or even be dispensed with such manipulation units.
    This object of the invention is achieved by the measures according to claim 1, in particular by a winding machine, in which the spindle unit is arranged on a pivot mechanism, whereby the finished wound coil can be stored on a located below the spindle unit conveyor or a winding tube, which transported by this conveyor technology, can be recorded. By combination with the corresponding conveyor technology, an advantageous production plant according to claim 15 is formed. Furthermore, the object of the invention is also achieved by a method for operating such a winding machine according to claim 16.
    According to the invention, a winding machine for winding from a belt to a winding tube, comprising a base frame, a spindle unit arranged thereon with a predominantly horizontally oriented in a winding position spindle axis, which spindle unit has a spindle and a spool for receiving the winding tube. Furthermore, a drive unit for rotational drive of the spool of the spindle unit is provided. In addition, the spindle unit is connected via a pivoting mechanism to the base frame, with which pivoting mechanism the spindle unit can be transferred from the winding position by a pivoting movement into a bobbin changing position, in which the spindle axis is oriented approximately vertically.
    An advantage of the embodiment of the invention is that the possibility of pivoting the spindle unit, the entire winding machine can be built to save space. Furthermore, this allows the manipulation of the finished wound coils and / or the empty cores are realized via a below the spindle unit conveyor technology. This conveyor technique can be simple and therefore less susceptible to errors and robust.
    Furthermore, it can be provided that the pivot mechanism is arranged on a side facing away from the receiving device of the spindle unit side. The advantage here is that the pivot mechanism can be mounted near the center of gravity of the spindle unit, whereby the force required to pivot the spindle unit can be kept low.
    Furthermore, it can be provided that the spindle unit is adjustably guided and supported relative to the base frame in a direction parallel to the spindle axis by means of a guiding and adjusting device. The advantage here is that by the possibility of the axis-parallel adjustment of the spindle unit, the recorded on the spool winding tube can be stored on a arranged below the spindle unit level.
    In addition, it can be provided that below the spindle unit, a conveyor for conveying coils wound on cores and / or empty cores is arranged in the horizontal direction. Such a conveying technique may be advantageous, since it is simple and thus robust and inexpensive to purchase and in operation.
    Furthermore, it may be advantageous that in the bobbin changing position of the spool of the conveyor technology is turned. As a result of this measure, an empty winding tube can be picked up by the conveyor or a ready-wound coil together with a winding tube can be dispensed onto the conveyor.
    According to an advantageous development, provision can be made for a centering device to be attached to the base frame, by means of which the winding tube to be accommodated by the spindle unit can be aligned coaxially relative to the spindle axis. By using a centering device for cores can be made possible that the cores can be easily absorbed on the spool, and that possible no damage to the winding tube by the moving in the vertical direction Spuldorn occur.
    According to a development it can be provided that the pivoting mechanism comprises a locking device, by means of which the spindle unit can be locked in the winding position and / or in the bobbin changing position. An advantage of using a locking device is that the pivoting mechanism can be fixed in its position, whereby the security, as well as the functional performance of the winding machine is improved.
    Furthermore, it can be provided that the pivot mechanism comprises an actuator, by which the spindle unit can be transferred from the winding position into the bobbin change position. It is advantageous that by an actuator, which is adapted to the requirements of the pivot mechanism, an optimal performance can be achieved. For example, the actuator may be configured in an advantageous embodiment as a pneumatic pivot cylinder. Such an embodiment would have the advantage that the actuator can be implemented easily and inexpensively, and yet the functionality of the actuator is guaranteed. Another conceivable variant of such an actuator can be realized for example by means of a servo motor.
    In a development, it can be provided that the swivel mechanism comprises sensors, by means of which the swivel position of the swivel mechanism can be detected. The advantage here is that the machine safety can be increased by the use of sensors for detecting the pivot position of the pivot mechanism, and the error rate of the machine can be reduced because the machine control, the position data can be provided.
    Furthermore, it may be advantageous that the spool comprises a plurality of fins, which are mounted adjustable in the radial direction with respect to the spindle axis. By this measure can be achieved that a winding tube can be held by frictional engagement.
    Furthermore, it may be appropriate that the spool comprises at least one spring element, with its spring force, the lamellae of the spool are each movable to a side remote from the spindle axis side and is held by the lamellae the winding tube in a clamping position. The advantage here is that even in the case of a power failure, the winding tube can continue to be held on the spool with a sufficient clamping force.
    Furthermore, it can be provided that the spool further comprises an adjusting device, with which the acted upon by the spring force slats are movable from the clamping position into a release position for the winding tube. The advantage here is that the winding tube can be easily removed by transferring the slats of the clamping position in a release position from the spool.
    According to an advantageous embodiment it can be provided that the spindle unit comprises a mechanical coupling, by means of which the spool is fastened to the spindle. By this measure, different cores can be clamped to each other with different inner diameters on the winding machine, since different spool pins can be clamped with different effective diameters on the spindle.
    Finally, it can be provided that the laying unit is designed to guide bands having a width between 3 mm and 50 mm, in particular between 5 mm and 35 mm, preferably between 8 mm and 25 mm. It is advantageous in this case that these dimensions are the most common dimensions for packaging tapes, and thus all types of packaging tapes can be wound on a winding sleeve formed on such a winding machine.
    The invention further relates to a method for winding a tape on a winding tube held on a spindle unit of a winding machine, in which the tape is wound in a predominantly horizontally oriented winding position of a spindle axis of the spindle unit. In this method, the spindle unit is further adjusted by a pivoting movement in a bobbin changing position after completion of the winding process for depositing a finished wound on the winding tube coil, while the spindle axis aligned approximately vertically. It is advantageous here that by pivoting the spindle unit, the finished wound coils and the empty winding tubes can be manipulated by means of a conveyor system located below the spindle unit. This conveyor technique can be simple and therefore less susceptible to errors and robust.
    Furthermore, it can be provided that after positioning the spindle unit in the bobbin changing position, the spindle unit is moved in the vertical direction to a arranged below the spindle unit conveyor technology and then the winding tube is stored together with the wound coil on the conveyor. The advantage here is that the winding tube together with the wound coil can be stored directly from the spindle unit gently on the conveyor.
    Furthermore, it can be provided that, after depositing the coil wound onto the winding tube, the take-up of a further empty winding tube onto the spindle unit is carried out by the spindle unit located in the bobbin changing position. The advantage here is that the empty winding tube can be easily absorbed directly by the spindle unit, and thus the winding machine for the next Wickelvorqanq is ready.
    Further, it may be appropriate that for changing a spool of the spindle unit, the spindle axis is pivoted in the approximately vertically aligned bobbin change position, and then uncoupled by a vertical adjustment of the spindle unit, the spool of the spindle unit and stored on the conveyor. It is advantageous here that the spool can be changed automatically, for which purpose no additional manipulation devices are necessary.
    Finally, it can be provided that a winding speed compensation device arranged upstream of the spindle unit in the transport direction of the belt is arranged on the winding machine, in which a linearly guided dancer roller is held in position by a spring. In this case, the spring has a spring travel between 5cm and 30cm, preferably between 10cm and 15cm, whereby an irregular tape speed can be compensated in a Bandzu-führabschnitt, whereby the tensile force of the tape in the Bandzuführabschnitt is kept approximately constant. Furthermore, in the winding speed compensation device is a force measuring unit attached, which passes the current tensile force of the belt to the machine control in order to adjust the speed of the spindle unit accordingly. The advantage here is that the tensile force of the tape in the tape feed can be kept fairly constant by the use of a dancer roll. This positive characteristic of a regulated tension in the tape feed section can be further enhanced by regulating the speed of the spindle unit.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.
    In each case, in a highly simplified, schematic representation:
    Fig. 1 is a perspective view of a manufacturing plant, as well as a winding machine;
    2 is a perspective view of the winding machine, but without covering the winding machine and without a base frame.
    3 a to j: perspective views of the winding machine in various stages of a process sequence;
    4 shows a view of the spindle unit with a section through the spool;
    Fig. 5 is a front view of the winding machine with representation of the band profile in Bandzuführabschnitt.
    By way of introduction, it should be noted that in the various described embodiments, the same parts are provided with the same reference numerals or the same component names, the disclosures contained throughout the description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and these position information in a change in position mutatis mutandis to transfer to the new location.
    Fig. 1 shows a simplified and perspective view of a manufacturing plant 1, which comprises a plurality of parts described in more detail below. The main component is a winding machine 2 for winding a tape 3. A wound on such a winding machine 2 band 3 is usually formed of a plastic material, in particular PET or PP. The tape 3 to be wound is provided by a tape supply 4. The tape supply 4 can be designed as a banding machine, for example an extrusion machine. However, it is also possible that the tape supply 4 is designed as a large-capacity memory, for example a very large tape roll.
    The winding machine 2 essentially comprises a base frame 5 to which a cover 6 is attached and which accommodates a spindle unit 7. The spindle unit 7 can comprise a plurality of components or assembly groups, which are shown in detail in FIG. 2 and are described in detail in the description of FIG. 2.
    Between the band supply 4 and the winding machine 2, a Bandzu-guiding device 8 may be provided, which comprises a plurality of individual units. Part of the strip feeding device 8 may be, for example, a cutting device 9, which cuts off the strip 3 at the end of the winding process. Another component of the strip feeding device 8 may be a laying unit 10 which guides the strip 3 to be wound laterally. By this guidance of the band 3 can be achieved that the wound tape 3 is evenly distributed on a winding tube 11. Furthermore, a winding speed compensation device 12 may be part of the tape feeding device 8. The operation or the individual components of the winding speed compensation device 12 are shown in detail in FIG. 5 and described in the description of FIG. 5.
    Fig. 2 shows the perspective and highly simplified view of a manufacturing plant 1 with winding machine 2, in which, for reasons of clarity, the base frame 5 and the cover 6 are not shown. Here, the otherwise covered by other components of the winding machine 2 are clearly visible. Good recognizable is the spindle unit 7, which is located in the currently displayed view in a winding position 13. The winding position 13 is defined by the fact that a spindle axis 14 of the spindle unit 7 is aligned substantially horizontally.
    The spindle unit 7 comprises a spindle 15, on which spindle 15 a spool 16 is arranged or fastened thereto. At the spool 16 opposite side, a drive unit 17 may be provided. Here, the drive unit 17, the spindle 15 in a rotational movement, which is passed to the spool 16. Of course, it is also conceivable that the spool 16 is not connected via a spindle 15 to the drive unit 17, but that the spool 16 is attached directly to the drive unit 17. Furthermore, it can be provided that the drive unit 17 is connected via a belt drive or via a countershaft with the spindle 15 or with the spool 16. The drive unit 17 may preferably be formed by an electric motor, in which the speed is variably adjustable. However, it is also conceivable that, for example, a pneumatic or hydraulic drive is used. In any case, the drive unit 17 must have a movable torque absorption to the base frame 5 in order to transmit the transmitted from the drive unit 17 to the spool 16 torque.
    The spindle unit 7 is connected via a pivot mechanism 18 to the base frame 5, by which pivot mechanism 18, the spindle unit 7 is pivotable in and out of the winding position. The pivot mechanism 18 is shown symbolically in all figures shown as an axis. It should be noted that to achieve the desired functionality of the pivot mechanism 18, for example, a sleeve can be used, in which the spindle 15 is received stored. On this sleeve outside diametrically opposite two bolts may be mounted, which engage in a mounted on the base frame 5 pivot bearing. As a support for fixing the positions of the pivot mechanism 18, a locking device 19 may be provided, which may for example be designed as a locking pin. The locking device 19 is indicated in Fig. 2 as an axis and can be adjusted in their position on the spindle unit 7, or in their embodiment to the respective requirements.
    In a further embodiment, it is also conceivable that the pivot mechanism 18 is mounted directly on the drive unit 17, for example. Thus, the pivot bearing and the torque absorption between the drive unit 17 and the base frame 5 can be realized by means of only one structural connection. In addition to these embodiments, of course, other embodiments can be realized.
    As a further component in Fig. 2, a filming device 20 is clearly visible, which can be used to wrap the finished wound coil 23 with a film. Thus, on the one hand the surface of the coil 23 is protected and on the other hand, the coil 23 are held together to prevent the independent unwinding of the tape 3. The Foliereinrichtunq 20 can be equipped with films un ferent width to easily and quickly wrap various possible coil widths can. The Foliereinrichtung 20 may further have a level indicator, which signals the machine control the current film level. As a result, when a minimum level is reached, the film can be automatically changed by a manipulation device or the machine operator.
    Another device, which may be part of the manufacturing plant 1, is a Prüfmeterbox 21. This Prüfmeterbox 21 is used for quality control at periodic intervals or in predetermined by the user intervals a test piece of the tape can be removed to subject this to a control , The storage of the test piece in Prüfmeterbox 21 is fully automatic. It is advantageous if the test piece, which is removed after completion of a winding process or before the start of the next winding process, can be removed fully automatically. Advantageously, the removal process is carried out as possible during the setup process on an empty winding tube 11 on the spool 16, so that the machine times remain as low as possible.
    Another illustrated in Fig. 2 element, which can be used in the manufacturing plant, is a light barrier 22, which serves to secure access in terms of occupational safety.
    In order to feed a finished wound coil 23 to a downstream flanging system, a conveyor 24 may be provided, which is used for the manipulation of the finished wound coils 23 or for the manipulation of the empty cores 1.
    The conveyor 24 may be formed by one or more conveyor belts or else as a chain conveyor or roller conveyor. Other known from the prior art conveyors can be used. The conveyor 24 is preferably coupled to a further conveyor 25, which is used for the removal of the finished wound coils 23 and for the transport of empty cores 11.
    3a to 3j show a possible process sequence of a winding process, as can be realized with a winding machine 2 shown and described here.
    It should be noted that in this procedure, not necessarily all individual steps must be run through, but rather that the timing of the individual process steps can be changed or even that individual process steps can be omitted or that further process steps may be added. Since the representation of the manufacturing plant 1 or the winding machine 2 is purely conceptual, it is also pointed out that the individual device parts can be realized in their structural features, differently than shown here, in order to achieve their full functionality.
    FIGS. 3a to 3j show a production plant 1 together with the devices described above and a winding machine 2. For reasons of clarity, the representation of the base frame 5 or the cover 6 of the winding machine 2 has also been omitted in all these figures.
    In Fig. 3a, the winding machine 2 is shown during the winding process. Here, the spindle unit 7 is positioned so that the spindle axis 14 is aligned substantially horizontally and thus the spindle unit 7 is in the winding position 13. In the illustration in Fig. 3a, the band 3 is already largely wound on the winding tube 11 to form the coil 23 and the winding process can now be completed.
    Preferably, a measuring device is integrated in the belt feed device 8, which also logs the already supplied amount of tape and thus can ensure that a predetermined and desired amount of tape is wound onto the spool 23.
    Now, if this predefined amount of tape is reached, the coil formed by the belt 3 23, which is wound on a winding tube 11 and which winding tube is clamped on the spool 16, stopped. Now, the cutting device 9 is used, which cuts off the finished wound strip 3 and thus separates the finished wound coil 23 from the strip supply 4. Preferably, the cutting device 9 is designed so that it can not only separate the band 3, but also clamp the band 3 and thus can hold ready for the next winding process.
    Furthermore, during or after the cutting process, a soft winding roll 26, which is part of the laying unit 10, presses on the end of the coil located on the coil, so that wound on the winding tube 11 band 3 of the coil 23 thus produced can not unwind independently. The exact mode of operation of the soft winding roll 26 will be described in more detail in the description of the figures for FIG. 3h.
    Since both tape ends can be fixed by the measures described above, then the filming device 20 can be used to provide the finished wound coil 23 with a film wrapping.
    After completion of the Foliervorganges the spindle unit 7mitsamt the winding tube 11 and the wound thereon coil 23 can be pivoted in the pivoting direction 27 down to allow a Spulwechsel. To accomplish this pivoting operation, an actuator 28 is used, which can move the spindle unit 7. The actuator 28 can be designed as an electric servo motor, for example as a servomotor. Furthermore, it is also conceivable that the actuator 28 is realized as a pneumatic or hydraulic rotary or linear cylinder. Since essentially only two pivoting positions must be approached, the design as a pneumatic or hydraulic cylinder represent a cost effective and simple embodiment.
    To determine the current angular position of the spindle unit 7, one or more sensors 29 can be provided. These sensors 29 may be embodied, for example, in the form of a rotary potentiometer, which constantly detect the absolute angular position. However, due to the fact that only two angular positions have to be approached, it is also conceivable that the sensors 29 are designed, for example, as an end stop in order to be able to detect the reaching of the two end positions.
    If the spindle unit 7 is pivoted down to its end stop, then this is located at the end of the pivoting process, as shown in Fig. 3b, in a bobbin change position 30. In this bobbin change position 30, the spindle axis 14 is aligned substantially vertically. Via a guiding and adjusting device 31, the entire spindle unit 7 can now be moved downwards in the vertical direction 32 in order to deposit the finished wound bobbin 23 on the conveyor system 24 located below the spindle unit 7.
    In Fig. 3c, the spindle unit 7 is shifted so far in the vertical direction 32 down that the finished wound coil 23 together with the winding tube 11, the surface 33 of the conveyor 24 touches and thus has reached a lower end position.
    The lower end position 34 is not a fixed position, which is always the same, but it can vary. For example, if wider winding tubes 11 are tensioned on the spool 16, the lower end position 34 must be higher than if, for example, a Spuldornwechsel done.
    After positioning the spindle unit 7 in the lower end position 34 of the spool 16 can be transferred from the clamping position to the release position to release the frictional connection with the winding tube 11. The structure of the Spuldor-nes or the transfer of the clamping position in the release position is described in more detail in Fig. 4.
    If the coil 23 together with the winding tube 11 is now deposited on the conveyor 24, the spindle unit 7 can again be moved upwards in the vertical direction 32 in order to remove the spool 16 from the winding tube 11.
    In Fig. 3d, the spindle unit 7 has been moved so far in the vertical direction 32 upwards until it has reached its upper end position 35. In this position, the spool 16 is completely moved out of the winding tube 11, wherein the winding tube 11 together with wound thereon coil 23 is completely free on the surface 33 of the conveyor 24. The winding tube 11 together with the coil wound thereon 23 can now be moved by means of the conveyor 24 in mostly horizontal direction 36 to the light barrier 22.
    Fig. 3e shows a position in which the winding tube 11 together with the finished wound coil 23 is placed on the light barrier 22, where it can now be checked for correct winding and / or correct foliation. Should an error or deviation from the desired values be ascertained during this check, then an alarm signal can be issued by the machine control to the operator, whereafter the operator can check the condition of the coil 23. Flierzu it seems to be useful if the area around the light barrier 22 is easily accessible to allow the operator this intervention.
    Even during this verification process, an empty winding tube 11 can be moved by the conveyor 24 in most horizontal direction 36 so that it is placed as possible coaxial with the spool 16. For this it must be mentioned that in order to keep the figure as simple as possible, a detailed representation of the conveyor 24 was dispensed with and this of course must be further subdivided in order to move or transport the empty winding tube 11 independently of the finished wound coil 23.
    At this section of the winding process it is also possible for a spool 16 to be deposited on the surface 33 of the conveyor 24 in order to exchange it for another spool 16. This other spool 16 may be formed, for example, with a different effective diameter, which is suitable for different sized winding tubes 11. Here, the spool 16 can be manipulated by means of the conveyor 24 and also a new spool 16 can be fed by means of the conveyor 24 of the spindle unit 7. Here, the spool 16 is optionally transported in a suitable transport device with the conveyor 24.
    In Fig. 3f, the empty winding tube 11 has been promoted so far from the conveyor 24 in the direction of finished wound coil 23 that this was placed almost coaxially with the spool 16 under this. To compensate for a possible offset or a possible positioning inaccuracy, it may be necessary that a centering device 37 is provided, which is to allow a coaxial positioning of the winding tube 11 to the spool 16. Now, if a coaxial positioning is achieved, the spindle unit 7 can be moved in the vertical direction 32 down to receive the empty winding tube 11 with the spool 16.
    In Fig. 3g, the spindle unit 7 is shown displaced so far down, so-that the spool 16 preferably fully engages in the winding tube 11. Now, the spool 16 can be transferred from the release position 44 in the clamping position 43. If now the empty winding tube 11 is frictionally clamped by the spool 16, then the spindle unit 7 can be moved upwards in the vertical direction 32 in order to lift the winding tube 11 away from the conveyor 24.
    Optionally, the spool 16 may be provided with elements which move radially outwardly from the spindle axis 14 after vertical dipping of the spool 16 into the winding tube 11 and by engagement with suitable recesses on the winding tube 11 or by gripping the underlying end face of the winding tube 11 lead to a positive fixation of the winding tube 11.
    3h shows the spindle unit 7, which has been moved so far upwards that it is in the upper end position 35. As a further method step, the spindle unit 7 can now be pivoted upwards in the pivoting direction 27 until, as shown in FIG. 3i, it is again in the roughly horizontal winding position 13.
    Subsequently, the tape end, which is held by the cutting device 9 can be fixed via a clamping device on the empty winding tube 11 so that it is ready for the next winding process. If the tape is now fixed correctly, then the spool 16 can be set by means of the drive unit 17 in a rotary motion, whereby the tape is wound onto the empty winding tube 11. In order to wind the strip evenly distributed over the width of the winding tube 11, it passes through the laying unit 10, which moves in the horizontal direction 36 in an oscillating movement over the coil width 38 and with increasing coil diameter in the vertical direction 32. In order to support the correct winding of the tape, a soft winding roll 26 may be provided, which rests on the outside of the coil 23 and thus on the wound tape 3 and this presses on the winding tube 11. While the winding process takes place, as shown in FIG. 3j, the finished wound coil 23 together with the winding tube 11 which has been deposited on the conveyor 24 can be moved away from the latter in the horizontal direction 36 from the light barrier 22 and fed to a further conveyor 25, at which For example, a storage unit can be connected.
    4 shows the section through a spool 16 and a winding tube 11. Here, the individual blades 39 can be seen, which can be moved in the radial direction 40 of the spindle axis 14 or moved away from the spindle axis 14. In order to clamp a winding tube 11 coaxially, at least two fins 39 are required, which are moved together coupled. Here, the blades 39 are pressed by a spring element 41 by their spring force respectively on a side facing away from the spindle axis 14 side. As a result, the lamellae 39 engage with the winding tube 11, whereby this e.g. can be clamped frictionally. By means of an adjusting device 42, the brought into clamping position 43 fins 39 of the spindle axis 14 can be moved and thus transferred to a release position 44. The adjusting device 42 can be designed, for example, as a pneumatic or hydraulic cylinder or as an electromagnetic device. As further illustrated in FIG. 4, the spool 16 is fastened to the spindle axis 14 by means of a mechanical coupling 45.
    Fig. 5 shows in a front view a schematic representation of a winding machine 2 in which the tape feeding device 8 is shown with its individual parts. As viewed in the transport direction 46 of the belt 3, a winding speed compensation device 12 may be connected in front of the spindle unit 7, which may comprise a dancer roller 47, which is held in position by a spring 48. The dancer roller 47 is adapted to compensate for an irregular belt speed 49 in the tape feed section 50. This can be realized in that the dancer roller 47 is guided linearly and by the spring 48 has a certain spring travel 51 available to keep the force acting on the band 3 tensile force 52 in the Bandzuführabschnitt 50 reasonably constant. By the spring travel, which is preferably between 10 and 15 cm, small irregularities in the belt speed 49 can be compensated.
    However, if the unevenness of the belt speed 49 does not move within a range within the limits provided for it, which can be compensated by the spring 48, then the actual pulling force 52 of the belt 3 can be measured via a force measuring unit 53 which is mounted in the winding speed compensation device 12 and be passed to the machine control, whereby the speed of the spindle unit 7 can be adjusted accordingly. It is also conceivable not to measure the tensile force 52 by means of a force measuring unit 53, but rather to determine this by means of a length measuring unit, for example, via the deformation of the spring 48.
    According to a particular embodiment of the winding machine 2 can be provided that the cutting device 9, the laying unit 10, the filming device 20 and the soft winding roll 26 on a common, movable in the vertical direction 32, carriage. This carriage may be mounted on guide rails, which may be attached to the base frame 5. In addition, it can be provided that the individual components are mounted on the carriage in the horizontal direction 36 movable and / or rotatable.
