Abstract
A stitchless seam comprises a first portion of material folded upon itself proximate an edge to define an overfolded end portion having overlapping edge and nonedge portions and a second portion of material positioned adjacent the overfolded end portion. A first portion of adhesive is interposed between the overlapping edge and nonedge portions and a second portion of adhesive is interposed between the second portion of material and the edge portion of the overfolded end portion. Energy may be applied, via an ultrasonic seam bonding machine or other means, to activate the adhesive portions. The seams may be used for items made of waterproof breathable laminate fabric material, such as garments and sports articles.
