Abstract

Abstract A method of cleaning the surfaces of guide rolls used in treating and processing cloth comprised of the step of passing a strip of material soaked in a cleaning fluid, such as water, in a continuous path over and in contact with the guide rolls. The method is preferably performed by attaching the strip of material to the cloth being processed and continuously passing it through the guide rolls following the cloth to remove any contamination that might have been accumulated on the rolls during processing. In the passage over the rolls, which are preferably reversed during the cleaning operation, the strip of material is squeezed against the rolls and the cleaning fluid assists in the removal of contaminants as the cloth wipes the roll clean.
