Claim:
Device for stacking of sheets ( 2 ), said device comprising: a high-speed printer ( 6 ) for printing the sheets ( 2 ) or at least one continuous web ( 5 ) which is cut to sheets ( 2 ), and a stacking device ( 11 ) for receiving sheets ( 2 ) in at least one flow (AS 1 and/or AS 2 ) thereof to the stacking device ( 11 ) and to transfer the sheets ( 2 ) in the flow (AS 1 and/or AS 2 ) thereof to at least one first stacking table ( 11 b ) in order to form thereon at least one stack ( 2 A and/or 2 B) of sheets ( 2 ), at least one second stacking table ( 11 c ) being provided for displacement in between two sheets ( 2 ) in the flow (AS 1 and/or AS 2 ) thereof when sheets ( 2 ) therein are transferred to the first stacking table ( 11 b ) such that the second stacking table ( 11 c ) divides or cuts the flow (AS 1 or AS 2 ) of sheets between the two sheets ( 2 ) and interrupts the formation of at least one stack ( 2 A and/or 2 B) of sheets ( 2 ) on the first stacking table ( 11 b ) and permits formation of at least one stack ( 2 A and/or 2 B) of sheets ( 2 ) on the second stacking table ( 11 c ) without interrupting or stopping the flow (AS 1 and/or AS 2 ) of sheets ( 2 ), the first stacking table ( 11 b ) being provided for displacement in between two sheets ( 2 ) in the flow (AS 1 and/or AS 2 ) of sheets when one sheet is transferred to the second stacking table ( 11 c ) such that the first stacking table ( 11 b ) divides or cuts the flow (AS 1 or AS 2 ) of sheets between said sheets ( 2 ) and interrupts the formation of at least one stack ( 2 A and/or 2 B) of sheets ( 2 ) on the second stacking table ( 11 c ) and permits formation of at least one stack ( 2 A and/or 2 B) of sheets ( 2 ) on the first stacking table ( 11 b ) without interrupting or stopping the flow (AS 1 and/or AS 2 ) of sheets ( 2 ), wherein a transfer device ( 11 m ) is provided to move or transfer one of the stacking tables ( 11 b , 11 c ) from a ready position (BL) to a receiving position (ML) in order to cut or divide during this movement the flow (AS 1 and/or AS 2 ) of sheets between two sheets ( 2 ) and interrupt the formation of at least one stack ( 2 A and/or 2 B) of sheets ( 2 ) on one other stacking table ( 11 b , 11 c ), wherein the transfer device ( 11 m ) has at least one driver ( 11 n ) for moving the stacking tables ( 11 b , 11 c ), the stacking tables ( 11 b , 11 c ), during movement upwards to the ready position (BL), are brought to cooperate with the driver ( 11 n ), and the stacking tables ( 11 b , 11 c ), during movement downwards while stacks ( 2 A and/or 2 B) of sheets ( 2 ) are formed thereon, are brought out of cooperation with the driver ( 11 n ), wherein the transfer device ( 11 m ) includes at least one endless belt for moving the stacking tables ( 11 b , 11 c ), the driver ( 11 n ) is located on the endless belt, and each stacking table ( 11 b , 11 c ) has at least one hole ( 11 p ) for engagement by the driver ( 11 n ).
