Abstract

Procedure for the retreading of tire covers whose tread is reinforced by a vulcanized reinforcement to the tread and composed of superimposed layers of crossed wires or cables, placed under the tread, in which the tread is replaced worn and the armor layers damaged by new elements, these elements being joined by vulcanization to the remaining portion of the cover, and characterized in that all the armor layers are removed because an annular precast element is placed on the casing comprising at least the layers of the armor and whose dimensions are those that must be on the retreaded cover, the wires or cables of these layers having the same orientations as the wires or cables of the removed layers and being joined to each other layers by rubber, and because this assembly is fixed to the casing by vulcanization in a manner known per se.
