Abstract: An improved apparatus and method for cleaning one or more of the rollers used in printing presses. Typically, the printing press features manual or automated devices for supplying cleaning solvent to the press during a washing operation. A blade assembly is pivotally disposed for engagement with the press roller. The blade assembly features a blade unit for scraping solid and liquid debris from the roller, and a receptacle trough for collecting used solvent as well as solid and liquid debris. In the improvement, a sheathing system is provided to supply protective sheath material to cover the blade assembly to keep the blade assembly clean during the washing operation. The sheath material preferably has a low coefficient of friction to prevent wearing of the components and is relatively thin to maintain the blade geometry for effective cleaning of the roller.

Abstract: An apparatus and method to provide confidentiality for the message content in copy received from an electrographic device is disclosed. Confidentiality is communicated to the apparatus by utilizing a confidentiality code mark on the first and last sheets of a set of copy for which privacy is desired. The confidentiality or non-confidentiality of the copy may also be communicated by using a last sheet of copy containing predetermined code marks. In one embodiment, the apparatus receives sheets of copy output from the elctrographic device and directs sheets of copy that are not confidential in nature into one output tray for removal. The apparatus directs sheets of copy that are confidential in nature into an assembly station for binding. After the last sheet of the confidential document is delivered to the assembly station, the bundle of copy sheets is advanced into a storage tray. The sides of the bundle of copy sheets are bound during its travel.
