Abstract

The device for cleaning idler rolls (1) of paper webs (C) in rotary printing presses, comprises, under each cleaning roller (1) and parallel thereto, at least one bar (4) whose nozzles (104) spray liquid solvent on command, the spray being sufficiently distributed at least on the portion of the paper web (C) which is about to come into contact with the cleaning roller (1), and which, during the cleaning of the latter, is made to advance in the same direction of operation, but at limited speed, and also it comprises means (8) which are activated, in the same cleaning phase, to cause the independent rotation of the cleaning roller (1), thus making it rub against the paper web (C) carrying the solvent and progressively bringing it into contact with this web over its whole surface, so that the dirt is removed by the said paper web (C) treated with solvent.
