Patent ID: 8728367

Claim:
A process for producing linear profiles ( 3 ) for a wiper rubber from an elastomer material, the profiles having at least one wiping edge ( 5 ), the process comprising the following steps: a. molding of the linear profile ( 3 ) from the elastomer material, b. complete or partial sheathing of the linear profile ( 3 ) by a thermoplastic material, c. vulcanizing the elastomer material sheathed by the thermoplastic material, and d. removing the thermoplastic material after vulcanizing the elastomer material, wherein the complete or partial sheathing is sufficient to avoid deformation of the wiping edge ( 5 ) until the elastomer material has been completely vulcanized, wherein the thermoplastic material has been selected from polyethylene terephthalate, polypropylene, polycarbonate, polyamide, and high-molecular-weight polyethylene having an average molecular weight of from 500,000 g/mol to 1,000,000 g/mol, and wherein the thermoplastic material does not enter into any adhesive bonding with the elastomer material.
