ABSTRACT:
A separating apparatus, to which the sheet material is transported in stacks via a stack transporting system, comprises a movable retaining means which reduces the separating gap before the stack is fed and is restored to its original width immediately before separation begins. This allows for the prevention of sheets being wedged in the separating gap, which would otherwise lead to a disturbance of the separation process. The design of a stationary retaining element having an integrated second, movable element allows for the formation of a stopping surface which protrudes beyond the stopping surface of the stationary part and is hit by the leading edges of the sheets in the stack. A toothed design of the new stopping surface allows for the leading edge of the stack of sheet material to be influenced selectively.
