  • Process for making an elastomer assembly
    Patent number: 6485597
    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.
