Abstract

Abstract A method of cleaning the surfaces of guiderolls used in treating and processing cloth is comprised of the steps of attaching lengths of guide cloths, which are provided with wiping surfaces on both sides, to lengths of the cloth being processed so that the guide cloth and the cloth being processed are continuously passed over the guiderolls. Dampening at least one or both of the guide cloth and the guiderolls so that the guiderolls are wiped clean as the guide cloths pass over them. Preferably, the guiderolls are reversed from the normal direction of rotation to assist in the cleaning operation.
