ABSTRACT:
Method and apparatus for coating a fabric with elastomeric stock, wherein improved impregnation of the interstices of the fabric is achieved, the method comprising concomitantly feeding both elastomeric stock and a fabric in pressurized contact with one another between mutually confronting stationary and movable surfaces. The mutually confronting surfaces converge toward one another and cooperatively define a pressure chamber terminating in a restriction orifice. The movable surface is driven in a direction of feed of both the stock and fabric to frictionally carry and wedge both into and through the pressure chamber, thereby causing the interstices of the fabric to be increasingly impregnated by the stock.
