Abstract
A method and an apparatus for stacking sheets conveyed continuously at a stacking point. With the assistance of a separating member (6, 7), which can be introduced into a natural gap between the upper side of a stack and the sheets conveyed in an overlapping manner, in the conveying direction from the rear side of the stack (4), two gaps are created one after the other, into which clamping jaws (9, 10) arranged at different heights can be inserted. By clamping the wad of sheets (13) located between the inserted clamping jaws (9, 10), with simultaneous lowering of the stack of sheets (4), a larger gap is created below the wad of sheets (10), into which an auxiliary stacking platform (11), located directly below the lower clamping jaw (9), can be introduced. Since the sheets of the wad of sheets are held by the clamping jaws (9, 10), there is no danger that sheets may slide due to the formation of a 'bow wave' at the front edge of the auxiliary stacking platform (11), as it is inserted.
