  • Method for connecting together material plies which are unilaterally thermoplastically coated
    Patent number: 4737212
    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.
