ABSTRACT:
The sheet-processing apparatus has a mechanically-rotated platen at its sheet-processing station, upstream, along the pair of powered transport rolls and upstream of them, at the outlet of the sheet magazine, a powered sheet-abstracting roll. A drive train powers the transport and sheet-abstracting rolls from the platen. A mechanical sensing finger is disposed in the nip of the transport rolls. As the finger is contacted by an end margin of a sheet, the roll-powering drive train is mechanically triggered to be uncoupled. Upon a uniform degree of subsequent rotation of the platen, a return mechanism recouples the drive train and re-cocks the trigger.
