Abstract
Abstract A linear fastening element is made by stringing a plurality of filament clusters, each of which is made from one or more intertwined filaments, on one or more linear members. The clusters are adapted to permit the gripping element such as a barbed hook to enter the interior thereto and to reversibly or permanently retain and hold the gripping element by filament engagement. The strung clusters can be applied to an article surface, formed into a sheet material or incorporated into a laminate structure. The linear fastening element and gripping elements are used to join two articles such as a decorative wall covering or panel to sheet rock or wall studs.
