Abstract (en)

[origin: US4366932A] A reel 12 for a web of packaging material, such as metal foil for wrapping cigarettes, is axially extendable outwardly from the machine base 10 to facilitate web roll replacement. Such extension, and retraction, is implemented by a double acting pneumatic piston and cylinder 30, 31 mounted within the hollow reel axle 16 between a central web 35 of the axle and a surrounding tubular housing 24. Fine transverse adjustments of the web feed are made by a bidirectional worm 50 driving a rotatable wheel nut 51, 52 in response to output signals from a lateral movement sensing unit 38.
