Abstract
A touch fastener having long and thin headed stems welded to and extending from, for example, a thin film, is made by orienting thin, hollow, drawn staple fibers between bristles of a brush, with no more than fiber ends sticking out of the brush, and then fusing a film to the fiber ends by direct welding. The fibers are then withdrawn from the brush as stems that are headed by heating their ends and allowing the resin to reform into an engageable head.
