A method and cleaning system to clean ink and coating from contact cleaner rolls. The contact cleaning rolls are located on a turret and as one contact cleaning roll is indexed sequentially out of contact with the imaging surface and into contact with a porous material another contact cleaning roll is indexed into contact with the imaging surface simultaneously. The porous material has a non-alcoholic solvent applied to clean the contact cleaning roll surface upon contact. The components found to create an efficient cleaning solvent for the CCRs include aliphatic ketones and alkylene halides. The aliphatic ketones are alkyl ketones containing from about 1 to 25 carbon atoms (with a preferred range of about 1 to about 10 carbon atoms). The aliphatic ketones contain solvents such as methyl ethyl ketone (i.e. the preferred solvent), methyl ketone, ethyl ketone, propyl ketone and butyl ketone. The alkylene halides are alkylene chlorides that contain about 1 to about 30 carbon atoms (with a preferred range of about 2 to about 12 carbons). The alkylene chlorides include methylene chloride, ethylene chloride and propylene chloride with methylene chloride being the preferred solvent.

Apparatus to clean ink and coating from contact cleaning rolls

A system for cleaning a substrate comprising bringing a contact cleaning web into moving synchronous contact with the surface of a member to be cleaned to clean the surface.

Web system

A system in which a contact cleaning cylinder is brought into moving synchronous contact with the surface of a cylindrical member to be cleaned to clean the surface.

Removal of particulates from cylindrical members

A coating system is disclosed comprising apparatus for coating webs comprising a rigid, elongated trough, a cylindrical applicator mounted for rotation about its axis within the trough, the trough having an arcuate upstream liquid retaining surface and an arcuate downstream liquid retaining surface closely spaced from the lower surface of the cylindrical applicator to define an arcuate coating zone which progressively narrows in the downstream direction, a manifold between the upstream liquid retaining surface and the downstream liquid retaining surface, the manifold extending substantially parallel to the axis of the cylindrical applicator, the arcuate downstream liquid retaining surface and the arcuate upstream liquid retaining surface extending from the manifold upwardly a sufficient distance along the periphery of the cylindrical applicator to retain most of any liquid in the coating zone, a wall at each end of the trough to retain the liquid in the coating zone, each of the walls being closely spaced from the adjacent end of the cylindrical applicator, and means for continuously introducing liquid into the manifold. A process for using this type of apparatus for coating webs is also disclosed.
