Abstract:
1. A method of manufacturing a fabric reinforcement which is of particular value in reinforcing endless belts, wherein at least two layers of fabric material are embedded in the fabric reinforcement and wherein the fabric reinforcement exhibits improved peel adhesion characteristics, said process comprising (1) impregnating a fabric material with a bonding agent in a plastisol to form coated fabric material, (2) applying a plastisol layer between two or more layers of coated fabric thereby creating a belt carcass, (3) continuously feeding the belt carcass into a double belt press which presses the impregnated fabric materials together with the plastisol layer(s) at a pressure of at least 5 psi to produce a preformed fabric carcass while (4) heating the preformed fabric carcass to a temperature which is within the range of about 360° F. to about 450° F. for a period of at least 6 minutes, (5) continuously withdrawing the fabric carcass from the double belt press.
