ABSTRACT:
The present invention provides a process for making an elastomeric web. Generally stated, the process includes moving a first web (26) along an appointed machine-direction (28) of the process, and delivering a plurality of elastomeric strands (30) moving along the machine-direction. The elastomeric strands (30) have been elastomerically stretch to an elongation of at least about 50 percent, and the plurality of elastomeric strands (30) have been laterally distributed along an appointed cross-direction (32) of the process. The elastomeric strands (30) are positioned at a spaced distance (34) from the first web (26), and an adhesive is applied to the elastomeric strands (30) and the first web (26) while the elastomeric strands are at the spaced distance (34) from the first web (26). A second web (36) is laminated to the first web (26) with the elastomeric strands (30) sandwiched between the first and second webs to provide an elastomeric laminate, composite web (24) attached together with the adhesive. The composite web (24) is allowed to elastomerically contract lengthwise by at least about 3 percent, and the composite web (24) undergoes a traverse winding into a roll.
