Abstract
A process for manufacturing a track formed from a circumferentially continuous belt made of elastomeric material and including an inner surface and an outer surface. The inner surface is provided with a plurality of drive blocks uniformly arranged on the circumference. The process includes a step in which a cylindrical inner mold formed by first and second cylindrical die-halves is assembled, the two die-halves being movable relative to each other in an axial direction to come into contact with each other at a joint surface. The inner mold includes a radially external laying surface provided with a plurality of uniformly spaced cavities for molding the drive blocks, each cavity being delimited in the axial direction by respective side walls of the first and second die halves. The joint surface of the two die-halves is axially closer to one side wall than to the other side wall. A device for stripping the track from the inner and outer molds is provided.
