ABSTRACT:
Apparatus for intermittently removing impurities from the periphery of a calender roll includes a rotary cleaning implement in the form of a brush or several felt discs and having an axial length in the range of 5-10 cm. The cleaning implement is reciprocable longitudinally of the roll along a suitable guide and can be driven back and forth by a motor so as to remove impurities which are detected by a mobile monitoring device. The latter can be mounted in or on a frame for the cleaning implement or is movable along the roll independently of the cleaning implement. The apparatus can be mounted at the inlet or outlet side of the nip of the calender roll with a companion roll. The frame for the cleaning implement can carry one or more nozzles which direct water or another liquid (such as a solvent) against the cleaning implement and/or against the roll, and one or more nozzles which blow jets of air against the periphery of the roll.
