  • Manually fed machine for the formation of tabs on sheet stock
    Patent number: 5277722
    Abstract: A manual feed machine for the application of tabs to sheet stock has a strip feeder for feeding a foil strip into the path of a sheet which is manually insertable beneath the cutter for the file strip to entrain a previously cut segment into the heating jaws. A die cutter downstream of the foil application can cut the tab after the jaw opens and the sheet is transported to the cutter. Only after the perimeter of the sheet has cleared the blade, is the previously advanced foil strip cut to form the next segment.
