The invention relates to a reinforcing member for elastomeric products, in particular for the belt bandage of a pneumatic vehicle tire, wherein the reinforcing member is a hybrid cord of at least one low modulus yarn having a modulus of elasticity of at most 100 mN / (tex ·%) and at least one high modulus yarn having a modulus of elasticity of at least 200 mN / (tex ·%) and wherein the hybrid cord is provided with an adhesive impregnation. The object is to provide a strength carrier for elastomeric products which, when used in the belt bandage of a tire, reduces its rolling resistance and ensures its durability and permits trouble-free tire building and vulcanization. The object is achieved by the low modulus yarn (s) having a cumulative fineness of at most 550 dtex, preferably of at most 250 dtex, in which the high modulus yarn (s) have a cumulative fineness of not more than 550 dtex, preferably not more than 250 dtex the hybrid cord has an elongation at break of at least 5%. The invention further relates to a method for producing such a reinforcement and its use. |
