ABSTRACT:
A method for fusion bonding a pair of articles consisting of a high melting point thermoplastic material which includes the steps of bringing each surface to be bonded into engagement with the contact surface portion of a heated platen, maintaining the engagement until the surface becomes fused, and thereafter bringing the fused surfaces together in face-to-face relationship until the fused surfaces become solidified. The method further includes the step, in each operative cycle, of abrading the contact surfaces of the platen to renew and expose the metallic surface thereof for engagement with the surface of the next thermoplastic article to be treated.
