Abstract: A mold for shaping a belt having teeth on opposite sides thereof has a hollow cylindrical mandrel with a surface configuration corresponding to alternate grooves and teeth to be formed on one side of the belt and a plurality of bars arranged side by side around the mandrel having surfaces facing the mandrel corresponding to the configuration of teeth and grooves to be formed on the opposite side of the belt. The bars are supported in radially spaced relation with the mandrel surface in slots in the peripheral surface of end members for the cylinder and are adapted to move under pressure radially inwardly.
