Abstract

A molding apparatus for manufacturing tire covers comprising at least two mold cavities, means for forming molded parts of a rubber tire cover in these cavities, the cavities being provided with holding riser grooves to prevent displacement of the halves, means to pre-work the rubber without any substantial curing before its configuration, means to pressurize the mold with gas and means to reunite the cavities that support the parts of the cover, to join together the respective parts.
