Abstract
An apparatus for producing 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 apparatus includes quasicylindrical inner and outer molds which travel in a curved path corresponding to the radius of curvature to be imparted to the curved tread.
