Abstract: The invention relates to a suction brake for use with a sheet conveyor configured to convey a succession of flat elements in sheet form along a conveying path between a first location and a second location, the suction brake comprising: a hollow body having an interior cavity and a face that defines a plurality of suction apertures that communicate with the interior cavity; an obturator arrangement coupled to the hollow body and moveable with respect to the suction apertures; the obturator arrangement being moveable between an open position, in which the obturator arrangement exposes the suction apertures to a maximum extent, and a restricted position, in which the obturator arrangement occludes the suction apertures to a maximum extent. The obturator may rotate or be linearly translated in moving between the open and restricted positions.

Abstract: A machine for processing individual sheets comprises at least one processing station, in particular in inkjet printing station, and a transport system (100) for transporting the individual sheets through the processing station, along a transport direction. The transport system (100) comprises at least one gripper conveyor (150) movable along the transport direction, for gripping one of the individual sheets defining a sheet position in transport direction. The transport system (100) further comprises at least one support conveyor (190) movable along the transport direction for supporting a region of the individual sheet, wherein the support conveyor (190) comprises a vacuum system for supporting the individual sheet on an interacting surface of the support conveyor, the vacuum system comprising a plurality of orifices in the interacting surface. The machine allows for efficient and flexible handling of individual sheets, in particular large format sheets of materials such as corrugated cardboard or other materials that have a certain degree of inherent stability.

Abstract: A sheet processing device has a moveable beam (36) that moves in the vertical direction, a gripper bar (30) for gripping a sheet that travels through the sheet processing device (10), and a gripper bar locking device (40) that can lock the gripper bar (30) in a precise position. The gripper bar locking device (40) has a locking lever (68) that is pivoting between a rest position and a locking position. The locking lever (68) is connected to a vertical linear guide coupled with the moveable beam (36) resulting in a precise, compact and simple system to lock the gripper bar.

Abstract: A hot foil stamping press has a pressing system for pressing a foil onto a sheet, a blow unit which is positioned at a distance to the pressing system for directing a stream of gas between the sheet and the foil. The stream of gas to detaches the foil from the sheet after each stamping cycle. A gripper bar is arranged between the blow unit and the pressing system for gripping the sheet. A flow guiding element is arranged between the blow unit and the pressing system, preferably on the gripper bar, for directing the gas from the blow unit between the sheet and the foil. Said element avoids the losses in the stream of gas due to the aperture that exist between the grippers in a typical gripper bar.
