ABSTRACT:
A blanket cleaner for removing dust, lint or ink from a blanket cylinder in an offset printing press during the uninterrupted course of a press run. A first fluid cylinder periodically urges a brush against the blanket cylinder and retracts the brush from the blanket cylinder. Retraction of the brush permits the dust and lint swept before the brush to fall onto a door of a lint catcher. The door is raised and lowered by action of a second fluid cylinder. Operation of the second fluid cylinder lags the operation of the first fluid cylinder by an interval of time sufficient to permit the dust, lint or ink to fall onto the door. In the preferred embodiment, the structure includes a device for removal of debris from the lint catcher.
