ABSTRACT:
A method of interconnecting first and second material plies, each having one side coated with a thermoplastic material uses continuously rotatable pressing rollers and a heating gas. The marginal edge portion of an uncoated side of the first ply is folded back upon itself to form a pocket along its edge and after a strip having thermoplastic coating on each side is folded lengthwise, it is inserted into the pocket. The marginal edge portion of a thermoplastically coated face of the second ply is then positioned over the folded-over marginal edge portion of the first ply. Thermoplastic material between the folded-over portion of the first ply and the marginal portion of the second ply and between the folded portions of the strip are then heated so that they become plastic and they are pressed together to press the portions to be bonded together. The apparatus includes a guide for the first ply constructed so that its edge is folded back upon itself to form the pocket and the firm thermoplastic strip which is first folded is directed into the pocket and guided so that its upper leg portion is positioned within the edge of the lower leg portion and the folded over pocket is guided by a curved extension of the guide so as to facilitate the continuous insertion of a lengthwise folded strip of thermoplastic material into the pocket.
