Device for cleaning surface of print cylinders supplies dry ice to nozzle to produce cleaning jet at sufficient speed to remove impurities

摘要

The device includes one or more nozzles (17) provided on a slide carriage (13) and dispensing cleaning medium to the e.g. cylinder surface. Dry ice is supplied by a supply mechanism to the nozzles and the nozzle produces a cleaning jet with sufficient speed in the direction of the cylinder surface so that when the dry ice particles strike the surface of the cylinder any existing impurities are removed. The nozzle can also be supplied with compressed air. It swivels perpendicular to the axis of rotation of the cylinder
