Patent ID: 7188654

Claim:
A belt bandage for a vehicle pneumatic tire comprising: a ply comprising strength carriers embedded in an unvulcanized rubber mixture; the strength carriers running essentially parallel to one another; and each strength carrier comprising a hybrid cord that includes a first twisted yarn having a high modulus of elasticity of at least approximately 25000 N/mm 2 and a second twisted yarn having a low modulus of elasticity which is no greater than approximately 15000 N/mm 2 , whereby the first and second twisted yarns are final-twisted together, wherein each hybrid cord has a final twist count that is essentially equal to an initial twist count of each of the first and second twisted yarns, and wherein for a cord count E in cords per 5 cm ply widths, a force F 1 at 2% elongation of each hybrid cord, and a force F 2 at 6% elongation of each hybrid cord satisfies the following relationships: F 1 ×E≧ approximately 600 N F 2 ×E> approximately 1500 N.
