MANUELL BESCHICKTE MASCHINE FUER DAS VORSEHEN VON REITERN AUF BLATTMATERIAL

摘要

A manual feed machine for the application of tabs, of thermoplastic foil material, to sheet, ie paper, stock has a strip feeder 25 for feeding a foil folded strip into the path of a sheet which is manually insertable beneath the cutter for the foil strip to entrain a previously cut segment into heating jaws 53. A die cutter downstream of the foil application can cut the tab after the jaw opens and the sheet is transported to the cutter, eg by a transport belt. Only after the perimeter of the sheet has cleared the blade, is the previously advanced foil strip cut to form the next segment. The strip feeder 25, jaws 53 and foil strip cutter may be pneumatically operated either by linear cylinders, in the case of the jaws and cutter, or, in the case of the feeder, by a rotary pneumatic drive 26 coupled to feed rollers (30, 32, fig 2). Trip switches, activated by the sheet, are provided to control the jaws time delay and dwell period and to control the sequence of operations. A modular, adjustable tabbing die may be provided in order to cut away the sheet adjacent to the foil segment.
