Abstract
A method for forming a plurality of fastener components comprises providing a composite web which includes a web of hook material. The hook material includes a hook base layer which has a longitudinally extending medial section located between first and second, laterally opposed, longitudinally extending side sections of the web of hook material. Each of the side sections has a plurality of hook elements which are integrally formed with the base layer and extend away from a base plane of the hook base layer, and the hook elements are configured to operably engage a selected, cooperating loop material to provide an operative fastening. The medial section has a relatively lower density of the hook elements per unit area, as compared to the side sections. The web of hook material has an extending section of carrier web material attached to extend laterally outboard from each of the side sections of the web of hook material. Each section of carrier web material may have an extending web of panel material attached to extend laterally outboard from each section of carrier web material. At least the web of hook material is divided along a serpentine division line which extends generally l…
