- the winding machine 10 can in particular be provided at the end of a paper or coating machine.
- the material web 12 is first guided over a web guide roller 16, deflected vertically upwards by this and then guided over a carrying drum 18, which forms a winding nip 22 with the reel 14 or with the winding roll 20 that is created.
- the material web 12 is guided over the lateral surface of the carrying drum 18 with a wrap angle of approximately 180 ° (partial area).
- the carrying drum 18 and the resulting winding roll 20 are largely kept in contact with one another during the winding process in order to maintain this winding gap 22.
- a next, still empty drum 14 ' is already kept ready in a primary bearing 24.
- the primary bearing 24 comprises two levers 28 which can be pivoted about an axis 26, of which only one can be seen in FIG. 1.
- the drum 14 ' can be displaced along a first guideway 30, which in the present exemplary embodiment is formed by part of a circular path.
- the center of the circle in question lies on axis 26.
- the primary drive 32 can be moved along the first guideway 30.
- the winding machine 10 also includes a secondary bearing 34 which, for example, can have a transport device 36 which can be moved on a linear guide (not shown). This transport device 36 is used to hold and guide a respective reel 14.
- rails 38 can be provided, of which only one can be seen in FIG. 1.
- the rails 38 are arranged parallel to the horizontal and fastened to a machine frame 40.
- a 'provided with bearing pins 14 on the rails 38 Tambour stored, which means that the weight of this main cylinder 14 and the wound reel is taken up by these rails 38 twentieth
- a drive device 42 which comprises two threaded spindles 46 (dashed lines) which act on the two reel ends and are each driven by an associated electric motor 44.
- the resulting winding roll 20 is moved together with the associated reel 14, for example by the transport device 36, along a second guideway 48 which is essentially Lichen runs horizontally, and lies in an imaginary first plane E1 perpendicular to the plate plane.
- the drum 14 can be acted upon by a secondary drive 50, which is designed as a center drive and can be displaced along the second guideway 48.
- the carrying drum 18, which can be driven by means of a merely indicated center drive, serves as a pressing drum, for example being held by a guide carriage 52 which can be moved on a guide 54 arranged essentially parallel to the rails 38 of the secondary bearing 34.
- the center point of the carrying drum 18, which serves here as a movable pressing drum, lies on an imaginary first straight line G1, which runs parallel to the second guideway 48. In the present case, the vertical distance between the support drum 18 and the rails 38 is thus constant.
- the carrying drum 18 forms the winding gap 22 with the winding roller 20 guided by the transport device 36.
- the next, still empty drum 14 ' is inserted obliquely above into the primary bearing 24 according to FIG.
- the drum 14 ' can then be transferred along the first guideway 50 from a winding position to a transfer position, as is indicated in FIG. 1 by dashed lines at the end of the guideway 50.
- the resulting winding roll 20 with the associated reel 14 is then transferred along the second guideway 48 into the finished winding position shown in solid lines and subsequently into a dispensing position again indicated by broken lines, from which the finished winding roll 20 is then, for example, by means of a crane can be brought out of the winding machine 10.
- the relevant web end can be wound onto the new, still empty drum 14 '.
- the still empty drum 14 ' is accelerated by the primary drive 32 before the transfer of the material web 12 and brought to the running speed of the material web 12.
- the travel speed of the transport device 36 guiding the winding roll 20 can be increased, for example.
- the carrier drum 18 remains in constant contact with the winding roll 20, which means that the carrier drum 18 is also tracked accordingly in this phase and the line force in the winding gap 22 is kept constant.
- the empty reel 14 'introduced into the primary bearing 24 first assumes a position indicated by the horizontal straight line G2 in which the vertical distance between this horizontal straight line G2 and the horizontal straight line G1 running through the center of the support drum 18 is less than the sum of the radii of the support drum 18 and the empty reel 14 '.

- the drum change is triggered.
- the material web 12 is separated by means of a separating device, not shown, transferred to the reel 14 'and wound up.
- the winding roll 20 can still be in contact with the carrying drum 18. In this case, it is only lifted completely off the carrying drum 18 after the reel 14 'has been wound on. In principle, however, it is also possible for an intermediate space to be formed between the winding roll 20 and the carrying drum 18 at the moment the drum change.

- the drum 14 ' is constantly driven by the primary drive 32. This primary drive 32 is thus also displaced along the first guideway 30.
- the transport device 36 and the secondary drive 50 for taking over the wound spool 14 ' can be shifted from the primary bearing 24 into the take-over position. While the transport device 36 takes over the wound drum 14 'from the levers 28 of the primary bearing 24, the secondary drive 50 is coupled to the wound drum 14', so that temporarily both drives 32, 50 are coupled to the drum 14 '. Thereafter, the primary drive 32 'is uncoupled from the drum 14' and is moved back along the first guideway 30 counterclockwise to the winding position.
- the increase in the winding diameter is compensated for by the pressing device 56 assigned to the carrying drum 18 by a corresponding displacement of the carrying drum 18.
- the increase in the winding diameter during a transfer of the winding roll 20 that is created along the second guideway 48 from the transfer position into the finished winding position is compensated for by the drive device 32 assigned to the reel 14 by a corresponding displacement of the reel 14 or the winding roll 20 that is created.
- the line force LK prevailing in the winding gap 22 is regulated or controlled by means of a pressing device 56 in the form of an electromechanical pressing unit 56.1, which has a receptacle 58 on both sides for the carrying drum 18 and / or the drum 14, the line force LK in the winding gap 22 via the displaceable carrier drum 18th and / or is set via the displaceable drum 14 and the line force LK is preferably kept constant at a predeterminable value.

Of course, the arrangement of the security element 82 is also possible in the region of the storage of the drum, this possibility not being shown.
- the invention creates a method and a winding machine of the type mentioned at the outset, that no system vibrations are generated as far as possible regardless of the operating state and that despite any unevenness that may occur in the upper surface contour of the winding roll on the one hand an exact setting, preferably regulation, of the course of the line force between the carrying drum and the winding roll is possible and on the other hand there are no air pockets between the individual layers of the winding roll. Furthermore, the "wrapped" web tension is to be maintained during almost the entire winding process.
