摘要： A method and apparatus for joining sheet material is disclosed in which the material to be joined is fed from supply rolls, a dry monofilament adhesive is interfed between the materials in the area thereof to be joined, the material and the interfed adhesive is then concurrently compressed and subjected to radio frequency heating energy whereby the adhesive melts and covers the sheet areas to be joined. The adhesive hardens as the material advances beyond the vicinity of the radio frequency field and is rewound on a take-up roll.

摘要： A METHOD FOR JOINING SHEET MATERIAL IS DISCLOSED IN WHICH THE MATERIAL TO BE JOINED IS FED FROM SUPPLY ROLLS, A DRY MONOFILAMENT ADHESIVE IS INTERFED BETWEEN THE MATERIALS IN THE AREA THEROF TO BE JOINED, THE MATERIAL AND THE INTERFED ADHESIVE IS THEN CONCURRENTLY COMPRESSED AND SUBJECTED TO RADIO FREQUENCY HEATING ENERGY WHEREBY THE ADHESIVE MELTS AND COVERS THE SHEET AREAS TO BE JOINED. THE ADHESIVE HARDENS AS THE MATERIALS ADVANCES BEYOND THE VICINITY OF THE RADIO FREQUENCY FIELD AND IS REWOUND ON A TAKE-UP ROLL.
