Apparatus for peeling off the leading edge of a receiving sheet from a transfer image carrier

摘要

An apparatus for peeling off the leading edge of a sheet of paper adhering to a moving transfer image carrier during the process of transferring a powder image onto the sheet. The apparatus includes one stripper member or a plurality such as three stripper members mounted in the vicinity of the transfer image carrier at the side on which the sheet is intended to be detached from the same. The one or several stripper members engage the moving sensitive surface of the image carrier at a balanced extremely low contact pressure and are adapted to be lifted off this surface by a peeled-off sheet of copying material. The strippers are continuously reciprocated in a direction transversely of the transfer image carrier and thereby likewise transversely of the advancing sheet so that the problem of traces that may be engraved into the surface of the transfer image carrier is virtually overcome and the useful life of the image carrier is substantially extended.
