Claim 1
Independent Claim
68 words
A METHOD OF WELDING PLASTIC WHICH COMPRISES PLACING TWO PIECES OF A PLASTIC MATERIAL IN CONTACT, ENCLOSING SAID CONTACTING PEICES IN A CHAMBER, EVACUATING SAID CHAMBER, CAUSING A WALL OF SAID CHAMBER TO EXERT PRESSURE ON SAID PIECES, IMPINGING RADIANT HEAT THROUGH SAID WALL ONTO THE AREA OF CONTACT AND HEATING THE SAME TO WELDING TEMPERATURE, AND CAUSING SUFFICIENT FLOW AT SAID AREA TO FORM A SMOOTH SURFACE.
