ABSTRACT:
A packaging machine that has improved features for feeding a web in the form of a continuous chain of bags through the machine while helping to maintain the web in proper alignment and proper tension, and having additional features for improved loading and sealing of the bags. The machine includes a jam prevention device having a prime mover driven damping sub-assembly which includes a seal bar and a reciprocatable seal pad and housing. The housing is spring-mounted on the clamping sub-assembly in a lost motion arrangement. Movement of the seal pad toward bring a loaded bag into contact with the heater bar sub-assembly is aborted if a sensor detects premature lost motion movement of the pad. Control structure either allows or disallows the sealing process to continue based upon sensor signals.
