1. A process for production of an item comprising a thermoplastic polyurethane, which has direct-contact adhesive bonding to a rubber and to an engineering plastic, which comprises plasma-treating the surface of a rubber item, then bringing the thermoplastic polyurethane into contact with the plasma-treated surface, and then applying the engineering plastic to the thermoplastic polyurethane,
wherein the method of plasma-treatment of the rubber is such that a plasma is generated by means of high-voltage discharge in a plasma source, this plasma is brought into contact with the surface of the rubber item by means of a plasma nozzle, and the plasma source is moved within a distance of from 2 to 25 mm with a velocity of from 0.1 m/min to 400 m/min relative to the surface of the rubber item. |
