Abstract
In an apparatus for separating sheet material from a stack, the latter rests on a movable pressure plate, by adapted to feed the stack to a withdrawal device. The pressure under which the stack is urged against the withdrawal device is dependent upon the density of the stack. For determining the density, the apparatus comprises a density sensor which determines the density of the stack continuously during the separation process at least in the region of the withdrawal device.
