A reinforcement layer for elastomeric products, in particular for the belt bandage of pneumatic vehicle tires, are hybrid cords which are arranged generally parallel to one another inside the layer and are composed of a first twisted textile yarn made of a first material and a second twisted textile yarn made of a second material. The ends of both yarns are twisted with each other and the first twisted textile yarn is a polyketone yarn. The reinforcement layer of hybrid cords for elastomeric products, in particular for the belt bandage of pneumatic vehicle tires, has a force-extension behavior that, when using the reinforcement layer as a belt bandage in pneumatic vehicle tires, ensures the simple production of tires, including vulcanization, and a great suitability to high speeds. To this end, the second twisted textile yarn is an aramid yarn. |
