Abstract
A radial tire forming blank supply apparatus for use in a radial tire building machine comprises a column rotatable about a vertical axis spaced from the rotating axis of a forming drum, a pair of cantilever beams one above the other provided on the column, and two pairs of bar-like clamps. Each the pair of bar-like clamps are secured to each the cantilever beam and movable radially toward and away from each other to clamp and release a green case therebetween. According to the invention the main carriage serving to fit a green case onto the forming drum does not interfere with any process steps to which the green case on the forming drum is subjected, during the interval from the time when the main carriage leaves the forming drum to the time when the main carriage is ready for receiving the next green case, so that the loss of time in transferring and handling the green case is completely eliminated in spite that the guide rails for the main carriage are commonly used for supplying tread bands, thereby remarkably improving the efficiency in production process of radial tires and contributing to saving space occupied by tire producing installations.
