Abstract: The invention relates to a stacking device (10) for placing sheet-shaped elements (P) in stacks in a forming machine (1), said stacking device (10) comprising:



a movable stacking surface (11), and
an actuating device (12) for moving stacking surface (11):

between a retracted position and a vertical forward position in a reciprocating back-and-forth motion for stacking sheets, and
between the retracted position and a stowed position to open an access to the stack of sheet-shaped elements (P),


characterized in that the actuator (12) comprises cam means configured to move the stacking surface (11) upwardly in the retracted position, in a raised position to be located above the top of the sheet stack.




The invention also relates to a machine forming sheet-shaped elements comprising at least one such stacking device.

Abstract: A sheet pile supporting assembly (24) for a sheet material processing machine is presented. It comprises a plurality of sheet pile supporting bars (28) and a movable guiding means for selectively moving one or more of the sheet pile supporting bars (28) from a retracted position to an extended position. Additionally, an automatic selection unit (30) is provided for automatically selecting the sheet pile supporting bars (28) to be moved to the extended position and for coupling the selected sheet pile supporting bars (28) to the movable guiding means. Moreover, a method for operating a sheet pile supporting assembly (24) for a sheet material processing machine is explained.

Abstract: The invention relates to an insert-sheet pick-up device (13) for an insert-sheet loading device (10) of a station for receiving copy (500). The pick-up device (13) includes a suction element (20) configured to pick up an insert sheet. The pick-up device (13) includes a pivoting axis (30) and at least one telescopic arm (33) including a proximal arm (33a), one end of which is fixed to the pivoting axis (30), and a distal arm (33b), able to move with respect to the proximal arm (33a), and one end of which is pivot-articulated to the suction element (20) to move the suction element (20) between a raised position and a lowered position according to a vertical movement of the suction element (20). Also, the invention also relates to an insert-sheet loading device, a copy-receiving station and a machine for processing elements in sheet form including the insert-sheet pick-up device.

Abstract: An insert sheet loading device (10) comprising a movable carriage (12; 12′) for inserting insert sheets into a receiving area (2) of a blank-receiving station (500). The movable carriage (12; 12′) has a plurality of longitudinal bars (27a, 27b). At least one longitudinal bar (27a) has a suction channel (35) leading out, via at least one suction opening (30), onto the surface of the longitudinal bar (27a) for receiving an insert sheet, the suction channel (35) is connected to a vacuum source (31) for holding, by suction, the insert sheet transported by the movable carriage (12; 12′). Also a blank-receiving station, a sheet-shaped element processing machine, and a method for transporting an insert sheet in a receiving area of a blank-receiving station are disclosed.
