APPARATUS FOR THE PRODUCTION OF SHOPPING BAGS HAVING REINFORCED HANDLE HOLES

摘要

An apparatus for the production of shopping bags provided with handle holes reinforced by welded-on tabs of thermoplastic synthetic resin film includes a unit for effecting cyclic stepwise advancement of film webs forming sides of each bag; a unit for punching handle holes into the welded-on tabs and devices for welding and severing of the films webs to form individual shopping bags transversely to the direction of the advancement of the film webs, as well as a device for feeding tabs of thermoplastic synthetic resin films to positions on the film webs and for welding the tabs to the film webs. The device for feeding and welding of the tabs comprising a turntable which is rotatable about an axis perpendicular to the advancing direction of the film webs which operates cyclically in synchronism with the stepwise advancement of the film webs.
