Abstract
For individually separating outer sheets (9, 109) of a stack (6, 106) in a holder (1, 101), in each case in the area of an outer sheet or an outer set of sheets a suction is generated for sucking at least a portion of an outer sheet or set of sheets (9, 109) from an initial position, away from the stack, to a discharge position. From that discharge position a sheet or set of sheets is discharged away from the stack (6, 106) by a discharge structure engaging the sheet or set of sheets. The suction assembly (12, 112, 212) in each case generates a pulsed suction in a position spaced from the initial position. As a result, the sheets or sets of sheets can be reliably displaced one by one to the discharge position, while the intended operation of the apparatus is little sensitive to the suction strength set.
