    摘要: 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.

    摘要: A bending machine for forming offset printing plates and conversion components for converting older model plate benders into bending machines capable of forming reverse bend plates. The plate bender includes a table support for the plate to be bent. The table is provided with edges having contours identical to the desired contours of the edges of the plate after bending. At least one of the end edges is provided with a die having a reverse bend component formed in it. The bend on one end of the plate may be formed in a conventional manner, while the reverse end bend of the plate is formed in a two-bend sequence by suitable structural components which in themselves may form a conversion system for older plate benders.
