Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
190 words
THE METHOD OF PROVIDING A MECHANICAL BOND BETWEEN THE EDGE PORTIONS OF TWO SUBSTANTIALLY CONTINUOUS SHEETS OF FIBROUS MATERIALS WHOSE MATING SURFACES CONTAIN A COATING MATERIAL THAT RESISTS PENETRATION OF LIQUID ADHESIVE INTO THE FIBROUS CONTENT OF BOTH SHEETS INCLUDING THE STEPS OF (A). CONTINUOUSLY ADVANCING EACH SHEET OF FIBROUS, MATERIAL AT A RELATIVELY HIGH RATE OF SPEED; (B) RUPTURING EACH SHEET AND ITS COATING MATERIAL ALONG ONE EDGE PORTION BY MEANS OF A KNURLED ROLLER, SAID RUPTURE CONSISTING OF A LARGE NUMBER OF MINUTE SERRATIONS PENETRATING THE COATING AND THE FIBROUS CONTENT OF EACH SHEET SUFFICIENTLY TO PREVENT THE ACCUMULATION OF ANY RESIDUE ON SAID SHEETS AND TO ALLOW THE FLOW OF AN APPLIED ADHESIVE IN A LIQUID STATE INTO THE FIBROUS CONTENT; (C) COLLATING THE RUPTURED SHEETS WITH AN INTERVENING STRAND OF A HOT THERMOPLASTIC ADHESIVE BETWEEN THE SERRATED PORTIONS OF THE MATING SHEETS; (D) AND THEN APPLYING PRESSURE TO THE SERRATED PORTIONS OF THE MATING SHEETS TO FORCE THE ADHESIVE THROUGH THE SERRATIONS OF BOTH SHEETS TO FORM A CONTINUOUS MECHANICAL BOND BETWEEN THE FIBROUS CONTENT OF ONE SHEET TO THE FIBROUS CONTENT OF THE OTHER SHEET.
