Abstract
A method of making a prevulcanized tread particularly useful for the recapping of tires having, in stress-free condition, a constant curvature in its longitudinal direction whose radius corresponds substantially to that of the tires to be recapped, the sole of the tread being concave, is characterized by the fact that the tread has two ends in its longitudinal direction. The method includes feeding continuously a strip of raw rubber to an inner mold moving about an axis in a curved path, closing an outer mold for the tread pattern with the inner mold so that the closed molds form a continuous molding space within which the tread is completely molded and vulcanized as the closed molds move together about an axis of rotation, and opening the moving molds to discharge continuously in the longitudinal direction the prevulcanized tread of constant curvature.
