Abstract (en)

[origin: WO2006052948A1] A new method of making and manufacturing pile weather stripping is described using a non-woven, e.g. a knitted pile that is either cropped or slit to the correct pile height. The pile is then precisely introduced to a singer using guides. After the singing process the knitted pile is guided into the extruder head where the base is extruded around the knitted pile. The density of the knitted pile weather stripping is controlled by adding or removing filling yarns, picks and changing of the yarn denier. The base thickness and configuration is a direct function of the extrusion head. A pile fin or fins can be added as a purchased raw good or extruded as part of the process. The inventive pile weather stripping allows for the fabrication of any pile height, pile density and backing configuration to include throat width, T-slot width, T-slot base depth and varying fin heights. The method can be used to make a weather stripping comprising pile extending from a backing, the pile comprising pile yarns, the backing being bonded to the pile, a synthetic fibre being interlaced with the pile yarns, and the backing trapping at least a part of the synthetic fibre in the backing.
