Patent

CA 2088916

A pile weatherstrip has an elongate base strip (10) carrying a pile of thermoplastic fibres (11). A zone (15) is formed adja- cent the base of fibres fused together and compressed to reduce their width. This provides a comparatively smooth and narrow zone that does not snag on the flanges of a carrier as the pile weatherstrip is inserted into the carrier. The zone (15) can be pro- duced by passing the weatherstrip through a nip formed by heated rollers (18). In an alternative embodiment, the fibres are fused together for their whole height. This has the additional advantage of providing an air-impervious barrier.
