ABSTRACT:
An improved bag-making and sealing device having a pair of spaced, upstanding, bag-locating and holding pins is provided which includes a low-cost, integral, synthetic resin pin-mounting assembly in the sealer base for biased, back-and-forth shifting movement of one of the pins in order to tightly hold a section of marginally apertured bag-making material during heat sealing operations. The sealer also includes a pivotally mounted pin assembly intermediate the relatively widely spaced main pins which is shiftable to an upright position for locating and holding a section of narrow bag-making material in cooperation with one of the widely spaced pins; when not in use, the intermediate pin is pivoted to a recessed, non-interfering storage position permitting normal heat sealing operations using standard width bag-making material. In preferred forms the base of the sealing device includes a cavity for holding a roll of tubular, two-ply, marginally apertured bag-making material, and a shiftable knife element mounted in the sealer base for cutting of the bag-making material after initial heat sealing operations are completed.
