Abstract
A vacuum blanket cleaning system is provided for removing dust, lint or ink from a blanket cylinder in an offset printing press during the uninterrupted course of a press run. Operation is effected by an air cylinder which periodically urges a brush against the blanket cylinder and retracts the brush from the blanket cylinder for replacement or maintenance. The action of the brush in combination with rotation of the blanket cylinder is such as to loosen dust and lint from the blanket cylinder, which dust and lint is then drawn into a vacuum system that surrounds the brushes.
