ABSTRACT:
An endless tread assembly is fabricated on a ring having grooves and ridges which mold the radially inward surface of the tread assembly. The ring is a thin walled cylinder having a single slit or gap. The tread assembly on the ring is suspended by rotatable wheels rollable on the inward surface of the ring, so as to position an arcuate portion of the ring and tread assembly between a fixed press arm and a single movable heated press mold shoe operable to mold about a 40 degree arc of the tread assembly between the shoe and the ring backed by the press arm. Lugs on the inward surface of the ring cooperate with a latch fixed on the press arm to index selected increments of the tread assembly and ring between the press arm and mold segment. After all arcuate increments of the tread assembly have been molded and cured, the ring is opened at the gap and then simply flexed to reduce its diameter sufficiently to remove the cured tread assembly. The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawing and the following detailed description.
