ABSTRACT:
An apparatus for cleaning the surface of a backing roll in a coater or a calender roll, wherein the roll is cleaned by spraying water on it and then scraping the water away from the surface or the roll with a doctor blade. Splashing of the water accumulating in front of the doctor blade is prevented by a rubber sheet extending down close to the tip of the blade, or alternatively, using a guide blade mounted in front of the doctor blade. The rubber sheet preceding the doctor blade isolates the water pond formed in front of the doctor blade from the surface of the roll, so that the rotational movement of the roll cannot induce turbulence and splashes.
