ABSTRACT:
An improved thermoplastic film heat bonding apparatus includes a heated seal bar, a support member supporting the heated seal bar for reciprocating motion against a platen and a resilient coupling between the support member and the heated seal bar to allow deflection of the heated seal bar with respect to the support member providing better conformance between the platen and the face of the seal bar contacting the platen for more uniform and repeatable heat seals. Springs are used to provide the resilient coupling between the support member and the heated seal bar. One mounting providing both resilient coupling and continuous adjustable spacing between the support member and the heated seal bar includes a bracket supporting a threaded member passed through the support member and a coil spring biasing the bracket and support member apart. The bracket is itself resiliently mounted to the heated seal bar also by compression coil springs. Further contributing to improved registration between the heated seal bars and the platen is a flexible, cantilever mounting of the platen. The heated seal bar support member is mounted on a support arm rotationally mounted at one end and biased against a cam at an opposing end. Rotation of the cam pivots the support arm back and forth reciprocating the support member and heated seal bar against the platen.
