Abstract
The disclosure relates to a winder for winding film trims for packaging machines. The winder comprises a drive, a winding mandrel and at least two winding rolls. The disclosure is characterized by an adjustment device for adjusting a torque threshold above which slip occurs between the respective winding rolls and the winding mandrel and/or between the individual winding rolls.
Claims16
A packaging machine comprising:
- a winder for winding film trims, the winder comprising:
- a winding mandrel;
- a drive for driving the winding mandrel;
- at least two winding rolls associated with the winding mandrel;
- and
- an adjustment device for adjusting a torque threshold above which slip occurs between the respective winding rolls and the winding mandrel, wherein the adjustment device comprises at least two cooperating permanent magnets disposed in a relative position in an axial direction of the winding mandrel and wherein the adjustment device is operable to adjust a position of at least one of the at least two cooperating permanent magnets in the axial direction of the winding mandrel to vary the relative position of the at least two cooperating permanent magnets.

A packaging machine comprising:
- a winder for winding film trims, the winder having
- a winding mandrel;
- a drive for driving the winding mandrel;
- at least two winding rolls associated with the winding mandrel;
- and
- an adjustment device for adjusting a torque threshold above which slip occurs between the respective winding rolls and the winding mandrel, wherein the adjustment device comprises at least two cooperating permanent magnets in a relative position in an axial direction of the winding mandrel, and wherein the at least two cooperating permanent magnets overlap an overlap distance in the relative position and wherein the torque threshold is determined by the overlap distance, and wherein the adjustment device is operable to vary the overlap distance to adjust the torque threshold.
