ABSTRACT:
Method for bonding a layer of thermoplastic polymer to the surface of an elastomer. A foamed elastomer having, preferably, an open-pore surface is used. The thermoplastic layer is pressed against this surface while it is heated by heat radiation, in particular laser light. The thermoplastic layer is transparent to this radiation, whereas it is absorbed by the surface of the elastomer.
