ABSTRACT:
A method for the production of patch-rubbers intended to repair radial-ply and bias-ply tires. The patch-rubbers, although having the same strength as those known, are more flexible and do not affect the original mechanical features and performances of the regions of the tires repaired therewith, and are also suitable to perform retreading operations on tires by both high pressure molding machines and autoclaves. The method consists in superposing the plies (1a, 1b), embedding a fabric made by fiber cords, in such a way that their medium axes diverge from the longitudinal or symmetry axes A of the patch-rubbers, and in superposing on the plies, a further ply (2) of smaller area having rectilinear metallic cords forming a different angle with the above mentioned axes A.
