The tire drum which has possessed the folding mechanism for the not yet vulcanization tire assembly

摘要

Being the tire drum which includes folding mechanism, we to have with two annular segments where the tire drum, is arranged around the medial axis and that medial axis, is left mutually, supports the bead core, the tire drum on both sides of the outer part part of the annular segment, to have the arm of 1 sets which have extended to axis direction, the arm to turn back and, in the 1st free end which is directed to the annular segment, 1st folding expedient, especially have the roller, in the 2nd end of opposite side, in axis direction in the portable possible arm support sectionThe arm is installed by the hinge, can provide the expedient which supports the tire constitution component at least in portion of the nearby, arm of the 1st free end, support means at initial position form the peripheral support surface for the tire constitution component, the part to which the tire drum, directing the 2nd end of the arm of both group to mutual one in axis direction, makes the arm support section move in order to make move, furthermore has the expedient which therefore, has been located, outside the annular segment of the tire constitution component, inside the annular segment of the tire constitution componentDirecting to the part which has been located, is expanded while pushing, the 1st free end in order to make axis direction and radial move, as for the arm, inside the aspect of radial from initial position it is possible to inclined position to tilt, support means have or more where the support surface for the tire constitution component is provided the support roller of one or two, the support roller revolution possibly is arranged on the arm.
