Abstract

An apparatus is arranged to clean a cylinder with cleaning liquid being supplied. The cylinder includes an outer surface to which impurities are adhered. The impurities are removed from the outer surface when cleaning. The apparatus includes a spray bar into which the cleaning liquid is directed with pressure. The spray bar comprises tube means which Includes nozzle holes formed therein for spouting the cleaning liquid. The tube means is formed of elastic material and elastically deformed by the pressure of cleaning liquid to open the nozzle holes and spout the cleaning liquid. The tube means is elastically restored, when the cleaning liquid is not directed with pressure into the spray bar, to close the nozzle holes.

Description

technical field [0001] The present invention relates to an apparatus for cleaning cylinders in offset printing presses, other printing machines, paper machines, converted paper machines, textile machines and the like. The drum includes an outer surface to which impurities are attached, from which the impurities are removed when washing. Background technique [0002] For example, foreign matter such as dry ink, lint, etc. adheres to the outer surface of the cylinder of an offset press or other printing presses. Therefore, it is necessary to clean the cylinder regularly to ensure the good quality of each printed product. [0003] In this case, an apparatus for washing a drum with a washing liquid as disclosed in US Pat. No. 5,109,770 is commercially available. In the apparatus of this US patent, cleaning fluid is introduced under pressure into the boom. The boom consists of a tube with holes directed towards the brush roll for spraying cleaning fluid. The brush roll is bro...
