Abstract

A novel apparatus and a novel method for manufacturing an endless rubber track for large vehicles such as tractors or earth moving machines. A plurality of sprocket-engaging core bar inserts (60) are disposed in the inner portion or inner diameter of the endless rubber track to engage the power drive mechanism of the vehicle. Rubber tread (230, 234) is disposed on the outer portion or external diameter of the rubber track. Although the rubber track is made in segments (230 232, 234, 236), it is completely vulcanized, and does not have discontinuous, unvulcanized regions between vulcanized segments. Rubber track is formed using at least two different mold assemblies (102, 142). In the first mold assembly, the interior and exterior portions of the rubber track are molded onto an adjacent section of the green belt (194) to form a second segment, and the second segment along with the adjacent unvulcanized first segment is vulcanized.
