procedures to loosen a sheets stack formed in a papierstapels, and device for implementation of the procedure

摘要

The method involves directly clamping a cuboidal material stack (4) e.g. paper stack, adjacent to a gripper between an upper rotatable roller (6) and a lower drivable roller (7) of a roller arrangement. The material stack is fed by driving of the lower roller for holding the stack between the gripper and the rollers, where diameter of the upper roller is smaller than that of the lower roller. The stack conveyed by the lower roller from a clamping region of the rollers is deposited on a support (34) by the gripper, and clamping of the gripper is released. An independent claim is also included for a device for executing a method of force-opening and ventilating a sheet material stack.
