Abstract
A method of forming a stitchless, adhesively bonded seam involves placing a first strip of adhesive between the outside surface of first and second sheets of material along an edge of the second sheet. At least a portion of a second strip of adhesive is positioned against a first portion of the inside surface of the second sheet along the edge thereof. The second sheet of material is folded such that a second portion 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.
