Abstract
(EN)
A female component for a refastenable fastening device having an elastomeric adhesive backing (34) and a multiplicity of fibrous elements (30) extending from the backing. The female fastening component is formed by a method comprising the steps of: providing a first lamina comprising an elastomeric, pressure-sensitive adhesive film having a first adhesive surface (31) and a second adhesive surface (33) opposed to said first adhesive surface, a relaxed orientation, an elongated orientation and preferably at least two regions of differential elongations; stretching said first lamina from said relaxed orientation to said elongated orientation; contacting a second lamina comprising a nonwoven web (30) with said first surface of said first lamina in said elongated orientation, thereby directly joining said second lamina and said first lamina to form a laminate; and relaxing said first lamina such that said second lamina is shirred to form catching regions capable of entangling the hooks (28) of a complementary male fastening component (20).
