Abstract: Shaped elastomer portions are to be produced on an elastomer seal. For that purpose the shaped elastomer portions are provided with a thermoplastic layer, preferably by co-extrusion. The thermoplastic layer is converted into a molten state by heating. The shaped elastomer portions are then pressed against oppositely disposed regions of the elastomer seal and cooled until the thermoplastic layer has hardened again and a fixed bond has occurred on the one hand in relation to the shaped elastomer portions and on the other hand to the elastomer seal.

Abstract: A window glass (3) is moveable relative to a motor vehicle door. A sealing arrangement (4) comprises on each side of the window glass (3) a sealing groove (9, 10) which is provided with a cover strip (12) of a thermoplastic plastics material in its regions which come into sliding contact with the window glass (3). The cover strip (12) is provided at least on its side facing the window glass (3) with a grooving which reduces or prevents squeaking noises.
