Abstract:
A method of applying a latex coating to a carpet secondary backing by means of an applicator roll and a metering roll which travel in reverse rotation and different tangential speeds. The carpet secondary backing travels between a pressure roll and the applicator roll and a film of a coating material is applied to the backing. The backing is an open weave structure and the coating is applied primarily to the strands of the backing and not particularly to the open area of the backing.
