Claim 1
Independent Claim
143 words
A MACHINE FOR CONSTRUCTING A CONTINUOUS PLASTIC SANDWICH FROM ROLLS OF PLASTIC MATERIAL BY DIELECTRIC BONDING IN A PATTERNED BOND WHICH COMPRISES PATTERNED PRESSURE ROLLER MEANS HAVING A RAISED CONDUCTIVE SURFACE PATTERN, ELECTRICALLY INSULATING MATERIAL ATTACHED TO SAID ROLLER MEANS BETWEEN RAISED PORTIONS OF SAID PATTERN, A CONDUCTIVE ENDLESS WEB WHICH IS ROLLER MOUNTED FOR CONTINUOUSLY TRAVELING IN WRAPPING PRESSURE ENGAGEMENT WITH SAID ROLLER MEANS OVER A SUBSTANTIAL ARC OF ENGAGEMENT TO COMPRESS SAID SHEET MATERIAL INTO CONTACT WITH SAID PATTERN, SAID ELECTRICALLY INSULATING MATERIAL PREVENTING MECHANICAL DISTORTION OF SAID PLASTIC MATERIAL DURING BONDING BY SUPPORTING SAID PLASTIC MATERIAL BETWEEN RAISED PORTIONS OF SAID PATTERN, MEANS TO ENERGIZE SAID ROLLER MEANS AND SAID WEB FOR DIELECTRICALLY HEATING SAID SHEET MATERIAL, AND MEANS INCLUDING SAID WEB FOR CONTINUOUSLY COOLING A PLASTIC SANDWICH WHILE RETAINING THE SHEET MATERIALS THEREOF IN REGISTER DURING THE COOLING PERIOD.
