ABSTRACT:
The sleeve 6 of a storage roller 3 is held by two supporting pins 4, 5 on a changing device 1 of a packaging machine. One supporting pin 5 is connected to a drive motor 9 for rotation of the supporting pin 5. The supporting pin 5 can be moved together with the drive motor 9 in axial direction 11 by an adjusting device 10. The exact position of the storage roller 3 or of the foil strip 2 unwound from the storage roller 3 can be measured by a measuring mechanism 28. With the changing device 1, it is possible to exchange or exactly adjust a storage roller 3, or correct the course of the unwound foil strip 2.
