Title: Apparatus and method for separating sheets from a stack that includes apulsed suction assembly

Abstract: For individually separating outer sheets (9, 109) of a stack (6, 106) in aholder (1, 101), in each case in the area of an outer sheet or an outerset of sheets a suction is generated for sucking at least a portion of anouter sheet or set of sheets (9, 109) from an initial position, away fromthe stack, to a discharge position. From that discharge position a sheetor set of sheets is discharged away from the stack (6, 106) by a dischargestructure engaging the sheet or set of sheets. The suction assembly (12,112, 212) in each case generates a pulsed suction in a position spacedfrom the initial position. As a result, the sheets or sets of sheets canbe reliably displaced one by one to the discharge position, while theintended operation of the apparatus is little sensitive to the suctionstrength set.
