Abstract: A production method for a glass run of EPDM material with a urethane slip layer and/or a flocked layer on its glass sliding area, whereby a primer layer for a urethane slip layer or a flocked layer can be co-extruded together with a glass run substrate of EPDM material. The primer layer is a polymer blend of NBR 40-80%, EPDM 20-60%, and SBR 0-35% by weight, respectively. Solventless urethane coating material is applied on each primer layer to form a urethane coat. Flocking is provided only on flocked layer area. The urethane coat is cured during vulcanization of the glass run substrate, and in this way a urethane slip layer and a flocking layer can be formed.

Abstract: A window enclosure strip is provided for a window mounted in a vehicle door. The strip includes a mount channel which cooperates with a mount member on the door. The strip also includes a glass run portion having an exterior glass contacting member and an interior glass contacting member which form a seal with the window pane when the window pane is in a closed position in the vehicle. Further, the seal strip includes a self-trim for the door interior and exterior. The mount channel is formed of a relatively stiff material so as to eliminate the need for an additional stiffening member. On the other hand, the interior and exterior glass sealing members are relatively soft for the purposes of sealing against water, air, and noise. A continuous cut-line seal is provided to bridge the gap between the door and the body and reduce wind noise and water intrusion.

Abstract: A glass run of the invention includes a furrow part on which a window glass moves and slides. The furrows of the furrow part are inclined at a predetermined angle with respect to the sliding direction of the window glass. When dirt or dust is deposited in between the window glass and the furrow part, it enters the furrows of the furrow part. The slanted configuration of the furrows of the furrow part, in combination with the sliding force of the window glass, moves dust or dirt along the furrows to a position where the dirt does not rub against the end face of the window glass. The structure of the invention keeps the window glass from undesirably rubbing dust or dirt, thus preventing an increase in sliding resistance and undesirable noise.
