Winder for winding of film residues

Rewinder (22, 35) for winding of film remnants (23) for packaging machines (1), comprising a drive (24), a mandrel (29) and at least two winding rollers (25a, 25b), wherein the winder (22, 35) a setting means (50) for setting a torque threshold has, above which a slip between the winding rollers (25a, 25b) and the mandrel (29) and / or between the winding rollers (25a, 25b) to each other occurs, wherein said adjusting device (50) at least (, 38b 37a, 37b, 38a) comprises two cooperating permanent magnets and the permanent magnets (37a, 37b, 38a, 38b) in the axial direction of the winding mandrel (29) are adjustable relative to one another, characterized in that by means of an intersection (S) of the tubular inner magnets (37a, 37b) to tubular magnet (38a, 38b) (25a, 25b) is determinable, the threshold torque of the winding rollers.
