ABSTRACT:
A heating system for joining plastic films which is capable of matching the potential of the laser. The system comprises a burner assembly and a workholder. The burner assembly includes a torch tip with an inner diameter of 0.016 inch which is capable of delivering a hot, concentrated flame onto a narrowly exposed film workpiece at a 15.degree.. The workholder includes a heat-conductive base roll and a plurality of hold-down rolls which expose an edge portion of approximately 0.0625 inch so as to prevent the plastic film from shriveling away from the joint. These features in combination permit the advantages both of high speed manufacture and of a high-quality bead seal.
