High speed mechanical straining process to provide extensibility to laminates for use in disposable absorbent articles

摘要

The present invention relates to a high speed mechanical straining process to provide extensibility to laminates for disposable absorbent articles (1) such as sanitary napkins, panty liners, and incontinence pads that have side wrapping elements (52) for folding around the side edges of the wearer's undergarment. The components are designed to automatically wrap the sides of a wearer's undergarments when the undergarments are pulled up by having zones of extensibility. Importantly the zones of extensibility (56) are created by a high speed straining process of a laminate which comprises two layers at least one of which has apertures. The layers at least in the extensible zones are joined to each other by a soldering step. <IMAGE>
