Abstract:
1. Device for transporting sheets ( 2 ) in a plant ( 1 ) in which a high-speed printer ( 6 ) is included for printing said sheets ( 2 ) or at least one continuous web ( 5 ) which is cut into sheets ( 2 ), said transport device ( 9 ) being provided to transport the sheets ( 2 ) in at least one flow (AS 1 and/or AS 2 ) thereof-or at least one continuous web ( 5 ) wherein the transport device ( 9 ) includes at least one vacuum means ( 9 b ) with at least one vacuum opening ( 9 c , 9 d ) which communicates with vacuum holes ( 9 e ) in at least one conveyor belt ( 9 a ), and wherein a vacuum generating device (VA) is provided to generate a vacuum in the vacuum opening ( 9 c , 9 d ) of the vacuum means ( 9 b ) such that said conveyor belt ( 9 a ) can engage and transport the sheets ( 2 ), characterized in that the vacuum generating device (VA) comprises a compressed-air generating device ( 9 f ) from which compressed air is fed or supplied to at least one ejector ( 9 g ) such that a jet (D) of compressed air therein generates a vacuum in the vacuum opening ( 9 c , 9 d ) in the vacuum means ( 9 b ) and in the vacuum holes ( 9 e ) in the conveyor belts ( 9 a ), and that the ejector ( 9 g ) is located in a vacuum means ( 12 and/or 13 ) around which the conveyor belt ( 9 a ) runs such that the ejector ( 9 g ) is located close to the conveyor belt ( 9 a ).
