Abstract
A vacuum forming process for manufacturing a transport tire from an elastomeric material that include steps of: in a mold having a cavity or annular area, positioning a transport tire core of plies, belt and beads that has been laid-up on a mandrel. Fitting a cover in sealing engagement over the mold top and fitting a cylindrical canister, that is open at a top end, through the center of the cover and into the mold center and pouring an elastomeric material mixture into the canister that includes a needle valve in its lower end that exhausts into one end of the mold annular area. The cylindrical canister includes a port for connection to a deep vacuum source and the cover includes a port that is for connection to a low level vacuum source, where the deep vacuum is to remove air from the elastomeric material mixture, and, after filling, is open to atmosphere, and the needle valve is opened to the mold annular chamber allowing the mixture to be pulled by the low level vacuum through the mold annular cavity, impregnating the transport tire core maintained therein.
