ABSTRACT:
A contact heating platen assembly includes an upright central standard, a plurality of inclined linking members pivotally mounted to the standard, and to a pair of opposed platen carriers on opposite sides of the standard, each traversing an arcuate path relative to the standard. Each of the carriers supports a heating platen and an electrical heating element for heating the platen. The carriers are spring biased into a collapsed position against the standard, but movable to an extended position relatively remote from the standard. To complete a fusion bond, a pair of workpieces are positioned on opposite sides of the platen assembly, each with a fusible surface portion positioned to be engaged by one of the platens when the assembly is extended. The assembly is extended whereby the heated platens engage the fusible surface portions. The platens are maintained against the surface portions until they are fused, then allowed to retract or collapse under the spring force. The assembly is then withdrawn from between the workpieces and the workpieces are moved into engagement with one another to complete the bond.
