  • Process for the butted connecting of the edges of a rubberized fabric intended for the manufacture of a carcass reinforcement, and the tire with radial carcass reinforcement obtained thereby
    Patent number: 4946525
    Abstract: The process for the butt connecting of the edges of a rubberized fabric wh is formed of reinforcement elements which are parallel to each other and spaced apart by a pitch p by injecting under pressure and heat between the reinforcement elements of the edges spaced apart by an amount d greater than 1.5 p, a rubber mix having properties of coherence and stretching in raw state which are greater than the same properties of the coating mix of the reinforcement elements. In the tire produced from such a fabric, the welding mix has a modulus of elasticity in tension which is greater than said modulus of the coating mix of the reinforcement elements of the radial carcass reinforcement.
