Transverse perforating apparatus for use in producing bags, has linear servo unit comprised of yoke sleeve, spindle, universal joint, drive shaft, bearing block, bearing, clutch, engine shaft and electric machine to rotate lever press

摘要

A track (1) is provided between a perforation measurer (6) and a groove roller (7) whose corresponding axles (2,8) are separated by an adjustable distance. An eccentric lever press (10) is rotated by a linear servo unit comprised of a yoke sleeve (12), spindle (13), universal joint (14), drive shaft (15), bearing block (16), bearing (17), clutch (18), engine shaft (19) and electric machine (20). An independent claim is also included for a transverse perforating technique.
