Abstract
An elastomer coated bias fabric for reinforcing power transmission belts and the like is disclosed wherein one surface of the fabric is provided with an uncured, tacky, elastomeric composition. The fabric is prepared by pre-impregnating the fabric, transversely stretching the fabric on a tenter frame, coating a latex composition on both surfaces of the fabric while maintaining the fabric in its transversely stretched condition, and after drying the fabric, overcoating one surface only of the coated fabric with a tackified, latex composition which may contain a chemical linking agent which enhances the bond between the elastomer and the fabric by forming a chemical bridge between them. A method for manufacturing coated fabric is also disclosed.
