摘要： A dry cleaning system for removing dust and lint on the fly from blanket cylinders in offset printing presses. The cleaning system includes a relatively small brush mounted for rotation about an axis substantially perpendicular to the rotational axis of the blanket cylinder. In operation, the brush can be reciprocally moved across the surface of the blanket cylinder and selectively moved into and out of contact with the blanket cylinder. The contact pressure of the brush is pneumatically controlled to maintain a predetermined, set pressure and the brush automatically retracts should the pressure source fail. The system can be operated to clean the entire width of the blanket cylinder or only the portion of it actually being used to print. A vacuum pickup is included with its separately mounted housing and the entire cleaning system is carried on a unitary support structure that is removably secured at its ends for quick and easy installation and removal.
