Abstract
As arc section of the casing 11 of a tire 10 to be retreaded is engaged on the outside by a mold element 15 defining a hollow mold chamber 17 and on the inside by a mushroom shaped counter mold element 16 configured to the inner contour of the casing. The relatively movable elements 15 and 16 are pressed towards each other to seal the chamber 17, and tread rubber is injected into the chamber and vulcanized to the casing. The mold elements are then retracted and the casing is rotated to a fresh arc section to thus retread the entire casing circumference in a stepped or successive manner.
