Abstract: A copying paper processing apparatus comprises a sorter, a stapling device for stapling sheets of copying paper sorted by the sorter, and a device for automatically selecting and setting a sort mode when a staple mode is selected and set. The processing apparatus may comprise a switch for selecting the stapling operation, and a device for automatically selecting and setting a staple mode when the staple selecting switch is turned on and a sort mode is selectively set. The processing apparatus may comprise a device for transmitting a signal indicating that there is no staple needle when the number of staple needles left in the stapling device is a predetermined number greater than the total number of bins of the sorter. The processing apparatus may comprise a device for inhibiting the operation of the stapling device when one of sensors respectively disposed in a paper-receiving base of the stapling device and a sorter bin of the sorter detects that there is no paper.

Abstract: An improved apparatus for forming sheet material assemblages includes a circular array of pockets which are sequentially moved through a plurality of feed stations disposed in an arcuate array. Sheet material is fed into each of the pockets in turn at the feed stations to form sheet material assemblages. A delivery conveyor conducts the completed sheet material assemblages from the circular array of pockets. A plurality of loader conveyor assemblies are provided to supply sheet material to the feed stations. One of the loader conveyor assemblies is disposed above and extends across the delivery conveyor. The loader conveyor assembly which extends across the delivery conveyor has a skewed discharge end portion which turns a stream of sheet material as it moves toward the feed station. To facilitate handling of the sheet material, a group of the loader conveyor assemblies are disposed in a group with main sections of the loader conveyor assemblies extending parallel to each other.
