ABSTRACT:
An apparatus for manufacturing an elastomer coated bias fabric for reinforcing power transmission belts and the like is disclosed wherein one face of the fabric is provided with an uncured, tacky, carboxylated elastomeric composition. In one embodiment, the fabric is prepared by pre-impregnating the fabric with a neoprene latex composition followed by coating the neoprene composition on both faces of the fabric while the fabric is transversely stretched, and after drying the fabric, overcoating one face only of the coated fabric with a tackified, carboxylated neoprene latex composition.
