摘要
The invention relates to a method for treating a sealing strip, particularly for motor vehicle door frames, of the type comprising, on the one hand, a part (1) with a U-shaped transverse section forming a grip, intended to fit over the top of a projecting element of the door frame, this part (1) forming a grip consisting of at least one elastomer in which a metal reinforcing member (2) is embedded, and, on the other hand a generally tubular strip (3) which is elastically deformable and contiguous with the part (1) forming a grip, at least one inextensile thread (5) preferably being embedded in the elastomer coating the reinforcing member (2) of the part (1) forming a grip, parallel to the walls of the U, preferably in the region of the neutral axis of the part (1) forming a grip. According to the invention, prior to the fitting of the strip over a vehicle door frame, at least a part (8a) of the strip (8) intended to equip a curved portion of the door frame is stretched out locally in order to impart a permanent extension to it.
