Abstract
Abstract A pile weather stripping is provided having a tape fabric of monofilament thermoplastic yarn, heat-welded along the tape edges to prevent ravelling. The weatherstrip is of the type having a central longitudinally extending woven pile area and two bare side areas for insertion into slots. The woven pile may also be heat-welded to the fabric on the back side of the tape, and the bare side areas may be formed from originally all-pile material by heat-melting and crushing flat the pile along these side areas to fuse the pile and fabric together.
