Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
136 words
A METHOD FOR FABRICATING AN ASSEMBLY OF TWO FOAMED POLYSTYRENE RESIN PIECES, SAID METHOD COMPRISING ENGAGING THE APPARENT SURFACE OF AT LEAST ONE OF SAID PIECES WITH AN IRON HAVING A HEATED SURFACE CONFORMING IN CONTOUR TO THE APPARENT SURFACE CONTOUR OF THE OTHER OF SAID PIECES IN THE AREA OF ENGAGEMENT OF THE ASSEMBLED PIECES, SAID HEATED IRON SURFACE BEING MAINTAINED AT A TEMPERATURE OF FROM ABOUT 250*F TO ABOUT 325*F. HIGHER THAN THE MELTING TEMPERATURE OF SAID POLYSTYRENE RESIN, MAINTAINING SAID PIECE IN CONTACT WITH SAID HEATED IRON SURFACE FOR A PERIOD ONLY SUFFICIENT TO FUSE THE SURFACE OF SAID PIECE TO SAID CONTOUR AND TO FORM A LIQUID RESIN LAYER ON SAID PIECE AND, BEFORE SAID LIQUID RESIN LAYER SOLIDIFIES, PRESS ING SAID PIECE INTO ENGAGEMENT WITH THE OTHER ONE OF SAID PIECES.
