ABSTRACT:
Cleaning cloth supply and take-up spools are mounted by rodless supports for rotation about spaced, parallel axes in a frame that is connected to a pneumatic cylinder for reciprocation between opposite ends of a rotating process roll the surface of which is to be cleaned. The cleaning cloth passes over an opening in the frame, and a sponge pressure pad, which is saturated with cleaning fluid, is mounted in the frame to reciprocate toward and away from the opening between an advanced position in which it engages, saturates and urges the registering portion of the clean cloth into contact with the surface of the rotating processing roll, and a retracted position in which the sponge is drawn into the frame completely to disengage the cloth, which therefore disengages the processing roll. The sponge pad retracts and a clean section of cloth is advanced over the frame opening each time the frame reaches one of its limit positions. The take-up and supply spool mounts are adjustable to preset the tension which is developed in the cleaning cloth during its use.
