ABSTRACT:
An apparatus for stacking, registering and attaching one or multiple sets of electrophotographic printing machine output. The copy sheets are discharged from the machine and fall into an inclined compiling tray and are longitudinally registered by flexible, endless belts contacting the top surface of each sheet. The belts are restrained from deforming and walking along the top of the stack by an idler member allowing greater stack capacity in the tray. Each sheet is then laterally shifted by a tamping mechanism to laterally register the sheet. Once a complete set of sheets has been discharged and fully registered the sheets of the stack are then attached by a stapler or some other sheet fastening or binding device and the stock is discharged from the compiling tray.
