Abstract: A sheet material handling apparatus includes a container handling assembly which is operable to sequentially position containers at an unloading station. An unloader assembly is operable to remove stacks of sheet material from containers at the unloading station. The unloader assembly includes a lift assembly which is operable to engage a stack of sheet material disposed in a container and to lift the stack of sheet material upwardly through an open lower end portion of an upright hopper.

Abstract: A multi-ream paper sheet feeder for use with high speed copiers, printing machines and the like "host machines" has a sturdy frame supporting an upwardly sloping ramp overlying a motor driven feed screw. A pusher plate drives a feed block of as many as thirty reams of edgewise stacked paper sheets up the ramp to a singulating feed assembly.

Abstract: A swing-up loader for a signature machine serves as an extension for the pile feed mechanism. The loader has its own conveyor belts and drive. When placed in its operating position, the loader adjoins the regular infeed of the signature feeder at a junction. A microswitch senses the height of the signature pile at the junction. When the pile height falls due to removal of signatures at the stockplate, the microswitch calls for movement of the loader's drive belts. This movement transfers signatures on the loader across the junction to the regular infeed of the signature feeder. The loader maintains a full infeed to assure a uniform pressure at the stockplate.

A proportional relation between the number of paper fed as counted by a paper counter and the number of encoder pulses which is associated with an amount of movement of the tray is calculated to determine how many pulse will appear before a near-paper-end condition is reached. Based on a result of the decision, the paper feed is controlled.
