patch for radial tire repair rubber, and repair method of radial tire using the same, and repaired radial tire

摘要

The present invention provides a repair patch of rubber radial tires which can improve the durability of the radial tire repaired by preventing premature failure of the radial tire repaired. In addition, to provide a radial tire repaired and repair method of radial tire using the rubber repair patch. A repair patch rubber radial tire that is constructed using a reinforcing cord layer formed by rubber-coated reinforcing plurality of cords which are arranged parallel to each other, a plurality of layers laminated for from one to the other reinforcing cord layer is composed of Te, a reinforcing cord layers code extending direction of the reinforcing cords are the same, and the imaginary line connecting the code end adjacent to each other of the plurality of reinforcing cords this, code parallel direction outermost one of a plurality of reinforcing cords this When the reinforcing region, a region surrounded by the reinforcing cords located towards, the reinforcing cord layer having the same direction, when viewed in the stacking direction, the code extending direction one reinforcing region of the reinforcing cord layer located on the other side is characterized in that it is located inside the reinforcing region of the reinforcing cord layer located on the side, repair patch of rubber radial tires.
