Abstract
A process for molding a tire elastomeric thermoplastic composite comprises a stage in which a layer of thermoplastic elastomer (TPE) is applied against one of the faces of the composite, followed by a molding stage for vulcanization of the composite and crosslinking of the layer of thermoplastic elastomer (TPE) with the neighboring layer of rubber material. The process furthermore comprises a stage consisting in applying a nonstick protective layer (12) against the thermoplastic elastomer (TPE) face intended to be in contact with the mold.

-22. (canceled)
A process for the molding of a tire elastomeric composite comprising the steps of:
- (i) applying a layer of thermoplastic elastomer to a rubber material of the tire;
- (ii) applying a nonstick film to the layer of thermoplastic elastomer;
- and
- (iii) molding an assembly by joint molding and vulcanization of a tire composite elastomer mixture comprising crosslinking agents and an adjacent thermoplastic elastomer layer devoid of crosslinking agents.
