ABSTRACT:
A sheet proofing mechanism for a printing, duplicating and like machine wherein sheets are delivered seriatim by a conveyor in a path over a receiving tray whereat the sheets drop onto a stack of sheets in the tray. Releasable gripping fingers are provided on the conveyor, and stripping fingers strip each released sheet from the conveyor and direct the sheet into the tray. A sheet proofing mechanism includes deflecting fingers spaced along the path from the stripping fingers for deflecting a released sheet from the conveyor to a proofing station. A tripping cam is provided along the path for selectively releasing the gripping fingers at a first point to allow the stripping fingers to strip the released sheet from the conveyor and at a second point to allow the deflecting fingers to deflect the released sheet to the proofing station. The machine also includes a numbering head for sequentially numbering the sheets, with an indexing lever for indexing the numbering head. The proofing mechanism includes an interrupter for preventing operation of the indexing lever whereby a given sheet will not be sequentially numbered and such that the given sheet can be selectively deflected to the proofing station without interrupting the remaining order of sequential numbering.
