Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
114 words
THE METHOD OF FORMING A SEAM BY HEATSEALING WITH RADIANT ENERGY BETWEEN THE SURFACE OF A HEAT-FUSIBLE MATERIAL TRANSPARENT OR TRANSLUCENT TO ELECTROMAGNETIC RADIATIONS AND A SECOND SURFACE OF THE SAME OR A DIFFERENT MATERIAL WHICH COMPRISES FORMING A SEAM-DEFINING STRIP FROM PERFORATED RADIANT ENERGY ADSORBENT MATERIAL CONFORMING TO THE SEAM AREAS BETWEEN SAID SURFACES, SAID RADIANT ENERGY ADSORBENT MATERIAL BEING NON-FUSIBLE AT HEAT-SEALING TEMPERATURE, POSITIONING SAID SEAM-DEFINING STRIP IN INTERPOSED RELATION WITH RESPECT TO SAID SURFACES AND THEN HEAT-SEALING SAID AREAS BY SUBJECTING SAID HEATFUSIBLE MATERIAL TO RADIANT ENERGY WHILE MAINTAINING THE AREAS OF SEAM BETWEEN SAID SURFACES IN CONTACT UNTIL FUSION OF SAID SURFACES OCCURS THROUGH THE PERFORATIONS IN SAID SEAM-DEFINING MATERIAL.
