ADHESIVELY BONDED SEAMS AND METHODS OF FORMING SEAMS

摘要

A method of forming a stitchless, adhesively bonded seam involves placing a first strip of adhesive (9) between the outside surfaces of first and second sheets of material (1, 2) along an edge (8) of the second sheet. At least a portion of a second strip of adhesive (13) is positioned against a first portion (17) of the inside surface (7) of the second sheet along the edge thereof. The second sheet of material is folded such that a second portion (18) of the inside surface overlies the second strip of adhesive. In some embodiments the first and second strips of adhesive are replaced by a single longitudinally folded strip of adhesive. Energy may be applied, via an ultrasonic seam bonding machine or other means, to activate the adhesive. Seams made according to the disclosed methods may be used for garments, sports articles, and other items made of fabric or other sheet material.
