Claims
- 1. A rubber patch for repairing radial-ply tires, said patch comprising:
- at least two superposed cord plies formed by rubber-coated fabrics of cords made of synthetic or natural fibers, the cords of each ply being mutually parallel and rectilinear, a longitudinal axis of each ply being superposed on a longitudinal axis of the patch, and
- an additional ply having metallic cords embedded in rubber,
- the cords of the at least two superposed plies form, in turn with the longitudinal axis of the patch, an angle greater than 0.degree. and less than 20.degree. in a clockwise direction in one of the plies and in a counter-clockwise direction in the other superposed ply,
- wherein when the patch is applied in such a way that the longitudinal axis is parallel to, or superposed on, the radial cords of a tire, the metallic cords of the additional ply are oriented either as the cords radially arranged in the sidewalls of the tire when the patch is to be applied on the sidewalls of the tire or as the parallel cords diagonally arranged in the tire belt when the patch is to be applied in an area of the tire belt or in an area of two corners that the tire belt forms with the sidewalls.
- 2. A rubber patch for repairing radial-ply tires as claimed in claim 1, wherein the patch is rectangular-shaped to repair damage to the tire belt.
- 3. A rubber patch for repairing radial-ply tires as claimed in claim 1, wherein the patch is a trapezoid shape to repair damage to the tire sidewall.
- 4. A rubber patch for repairing radial-ply tires as claimed in claim 1, wherein the plies are assembled by vulcanization.
