  • Negative-pressure control for a lateral pulling device
    Patent number: 6364311
    Abstract: A method of controlling negative-pressure level of a lateral pulling device for laterally aligning sheets through the intermediary of a rotary valve, includes having, during an accelerating phase of the lateral pulling device, a high-level negative pressure at a suction pull bar of the lateral pulling device; upon reaching a maximum and constant speed of the suction pull bar, a medium-level negative pressure at the suction pull bar; and, after reaching a desired pulling path of the suction pull bar, up to an end position of the suction pull bar, a low-level negative pressure and no negative pressure, respectively, at the suction pull bar; and a device for performing the method.
