ABSTRACT:
A device for cleaning the endless belt of a corrugator machine while the belt is moving and the machine continues in operation. The device includes a movable cleaning head incorporating a sprayer means for applying a forceful stream of cleaning solution to the belt for loosening debris and dissolving contaminants, and a vacuum means for removing the loosened debris and contaminated cleaning solution for recycling or disposal. The movable cleaning head is carried on a supporting track for transverse movement across the full width of the belt from edge to edge. The width of the head is 1/X of the width of the belt, and traverses the entire width of the belt at least once during each X circumferential belt revolutions past the head.
