Abstract: A hydraulic base-load motor (M1) drives a load with the working pressure generated at the motor rising with the load. When the working pressure reaches an upper limit pressure, a hydraulic stand-by motor (M2) is switched on. Since the pressure drops upon switching on the stand-by motor, the control device is designed such that, upon reaching a lower limit pressure, it deactivates the stand-by motor again, the lower limit pressure being less than half the upper limit pressure. This switching hysteresis prevents a repeated switching over of the stand-by motor.

Abstract: A moving bin sorter has a plurality of sheet receiving trays supported for shifting movement to enlarge the space between adjacent trays at a sheet entry location to facilitate the feeding of successive sheets forming a set of sheets into the successive trays. The trays are formed to allow a portion of a stapler to be moved from a non-stapling position to a position for stapling a set of sheets in the successive trays while displacing the previously stapled sets in their respective trays with another portion of the stapler to enable positioning of the stapler in its operative position to staple a set of sheets. The stapler may be mounted for movement relative to the successive trays for applying staples at more than one location in each set.

Abstract: An apparatus for controllably actuating at least two hydraulic actuator is provided. The apparatus controllably provides pressurized hydraulic fluid to the hydraulic actuators through closed center spool valves. The apparatus receives operating signals and a pump pressure signal and responsively controls the output of a variable flow pump. In a first mode, the output flow of the pump is a function of the operating signals and the pump pressure signal. In a second mode, the output flow of the pump is a function of the operating signals alone.

The apparatus has at least two sorters, a plurality of bins and a stapling unit in each sorter respectively to store a stack of recorded sheets sorted as a copy set and to staple each stack of recorded sheets and guide means to guide each recorded sheet to a bin of a sorter allocated by controlling means. The controlling means selects at least two sorters for making the copy sets larger in number then a predetermined number. The second sorter receives sheets even though some trays of the first sorter are left unused.

Abstract: Folded printed products, held at the fold thereof by clamps, are fed to an opening device. This opening device comprises grippers, each gripper having a stationary gripper jaw and a movable gripper jaw which delimit a slide gap in the closed position of the movable gripper jaw. Along this slide gap there is displaceable a pusher member for the purpose of pushing out of the slide gap the printed product gripped at its open-edge region by the respective gripper. The pusher member thereby acts upon a marginal lap of a first product portion which protrudes beyond the other or second product portion. By virtue of the pre-bending of the printed products, the second product portion is entrained during pushing action at the first product portion and, as a beneficial result of such bending, lifts off from the first product portion upon leaving the slide gap, the marginal lap of the first product portion still being guided in the slide gap.
