Abstract
An attachment for cleaning cylindrical surfaces, such as the surface of an offset printing press blanket cylinder, includes a sponge unit mounted in proximity to the cylindrical surface to be cleaned. The sponge unit is supported by a pair of pneumatic cylinders which, when activated, cause the sponge to bear in wiping engagement against the cylinder. A single elongated spray tube containing two sets of orifices, one set facing the sponge unit and the other set facing the cylinder, is mounted on the sponge unit and connected to a source of cleaning solvent under pressure. During a cleaning operation, the solvent is directed through the orifices of the spray tube toward both the sponge unit and the cylindrical surface adjacent the nip. The concentration of the solvent spray at this location results in the sponge cleaning the cylindrical surface without streaking. The sponge unit mounts on an elongated angle bracket and the spray tube is in turn mounted on the sponge unit. A plurality of screw and wing nut assemblies is used to mount the sponge and spray tube to permit a quick release and disassembly of the apparatus for maintenance. An upstanding shield isolates the cleaning attachm…
