ABSTRACT:
A machine for facilitating the simultaneous heating, bonding or sealing of a group of thermoplastic articles retained within a rotary sealing system. First and second rotatable workpiece carriers are arranged to transport the workpieces to be bonded, step-by-step, from loading stations to a heating station, and subsequently, to a bonding station, thereby accomplishing a plurality of operations on a simultaneous basis. The same drive mechanism used to incrementally rotate the workpiece carriers also imparts a reciprocating motion to the heating element and an arcuate reciprocating motion to the workpiece carriers for first applying heat energy to the workpieces for a predetermined time interval and for subsequently applying compressive forces to the heated workpieces undergoing bonding and thereafter releasing the now-joined workpieces from the carriers. There is a minimal movement required of the work, thus with the simultaneous occurrence of loading, heating, and bonding, the rate of speed for the system is substantially increased.
