Abstract (en)
A spray blanket cleaning system is provided for removing piling, lint and ink from blanket cylinders in a plurality of web or offset printing presses. Operation is effected by fluid control systems that direct solvent, water and air to spray systems in specific quantities and at specific pressures. The spray systems are point of use systems that mix solvent and water in a tube then eject the mixture to a connecting spray bar. The mixed fluid is then ejected by air pressure through the spray bar as sprayed fluid. The action of the spray in combination with the rotation of the blanket cylinder and the web, is such as to loosen dust, debris and lint from the blanket cylinder and collect it on the web passing out of the system. <IMAGE>
