ABSTRACT:
A method for joining together laminated material including layers of orientation-stretched polyester and glycol-modified polyester. A strand of molten glycol-modified polyester is applied to the laminated material along the joining area and the laminated material is pressed together while the strand is cooled. The laminated material is joined together by transferring heat from the molten strand to the pressed-on layers of the laminate. The surface portions of the layers are melted at the same time as the strand is cooled.
