Abstract: A pile stripping comprising pile extending from a backing is described whereby the pile is made from pile yarns and the backing is bonded to the pile. A synthetic fiber is interlaced with the pile yarns, and the backing traps at least a part of the synthetic fiber in the backing. The stripping can further comprise a fin, whereby the fin can be located within the pile or alongside the pile. The backing and the fin may be constructed so that the backing is inserted in the fin.

Abstract: 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.

Abstract: A generally L-shaped corner seal includes an elongated leg comprising a material having a first hardness and an integral shorter leg comprising a material having a second hardness less than the first hardness.
