Abstract
A splicing device comprising: an elongated anvil having an elongated slot therein; an elongated splicing head having a pair of spaced apart tips extending therefrom and having a longitudinal aperture therein; a heating element in the longitudinal aperture; and an actuator mechanism for driving one of the tips toward and into the elongated slot to weld two overlying polymer films together and the other of the tips into cutting contact with a polymeric film from a spent roll of film. According to various preferred embodiments, the splicing device further includes a pair of retaining members on either side of the anvil that serve to retain films to be spliced in taut contact with the anvil during splicing, and a turret section for rotating full and spent rolls of polymeric film into position for continued operation and reloading.
