ABSTRACT:
An infinite heat sealing assembly preferably for heat sealing a thermoplastic heat-shrinkable plastic film, has a heat sealing assembly for cutting and sealing a seam in a film or layers of film without regard to the length of the seam. The heat sealing assembly includes a heated blade and a plurality of belt conveyors for conveying the film with a desired tracking through the assembly. An adjustable angle blade and slotted film support ramp result in improved sealing of heavier gauge films by increasing the dwell time of the film on the heated blade.
