Abstract
An apparatus and process are used to make tape which can be used as cap plies, breakers and reinforcement in the carcass of tires. The tape is made by dipping a plurality of single end cords in a solvent-based cement. The cords are converged before entering the dip pan so that they are fixed in a single plane when they are dipped. The cement, which contains solvent and an elastomeric composition, is dried so that the majority of the solvent evaporates. The elastomeric composition remains, encapsulating the cords, thereby forming the tape.
