Elastomeric composites and elastomeric composite laminates including reinforcement strands incorporated into an elastomeric adhesive film. The strands may vary in terms of levels of tension. Facing layers, such as nonwoven webs, can be laminated to both surfaces of the elastomeric composite to form laminates. A method of making such composites and laminates involves adjusting tension among various elastic strands while extruding the elastic strands and incorporating the elastic strands into the elastomeric adhesive film.
We claim: 1. An elastomeric composite laminate, comprising: a plurality of extruded elastic strands adhered to an elastomeric adhesive film; and a first facing sheet bonded to a first surface of the elastomeric adhesive film and a second facing sheet bonded to a second surface of the elastomeric ad
