Vorrichtung zum vereinzeln von in einem stapel vorgehaltenen blättern

摘要

In a device for separation of sheets kept in a stack, pickup devices exert a pickup effect on the stack in order to push the upper sheets of the stack in overlapping fashion toward a separation device, which separates the uppermost sheet pushed forward the farthest from the following second sheet. The distance between the stack and the separation device can be adjusted as a function of the sheet quality and/or ambient conditions determined by sensors, like humidity and temperature.
