Abstract

Two sheets (10,14) are removed simultaneously from the sheet stack (1). While one sheet (10) is already in the transfer position, from which it is introduced into the conveyor line by two feed rolls (7,8), a first suction element (20) seizes the next sheet (14) from the stack (1). This sheet is moved along the curve a into the now vacated transfer position. A second suction element (30), which is no longer needed to hold the first sheet (10) there, moves to the stack (1) to seize the next sheet (15) and bring it to the transfer position, while the first suction element moves back to the stack. In this way, destacking can proceed at a faster rate than hitherto.
