A device for ejecting 1 a flat object 101 during the conveyance thereof along a conveying path 102 includes an inlet conveyor 10 and an outlet conveyor 20 which are successively arranged one after the other along the conveying path 102. At least the downstream part 11 of the inlet conveyor 10 is orientably mounted for pivoting between a conveying position and an ejecting position and at least the upstream part 21 of the outlet conveyor 20 is orientably mounted for pivoting between a conveying position and an ejecting position.

A sheet stacking system for transporting sheets and depositing them in a stack includes a layboy, a transport conveyor downstream of the layboy, and a main conveyor downstream of the transport conveyor, the main conveyor having a frame and being supported by a conveyor support, a discharge end of the main conveyor being movable between a lowered position and a raised position relative to the conveyor support. The main conveyor intake end is configured to move from a first position when the main conveyor discharge end is in the lowered position to a second position when the main conveyor discharge end is in the raised position, and also a variable length conveyor between the transport conveyor and the main conveyor, the variable length conveyor having a discharge end connected to and movable with the main conveyor intake end and movable relative to the transport conveyor discharge end.

A sheet transport system comprising an endless carrier belt that has a predetermined stiffness and is arranged to carry the sheets towards an end of a conveyer path where the sheet is separated from the carrier belt by passing this belt around a separating member that has a predetermined curvature, wherein the carrier belt runs in parallel with an endless conveyer that has a larger stiffness than the carrier belt and, at the end of the conveyer path, has a smaller curvature than the separating member.

An apparatus for diverting and/or folding articles includes an infeed conveyor, an outfeed conveyor, and a diverter. The diverter is a non-contact, fluid emitting diverter, configured to emit a fluid jet to exhibit the diverting force on the impact zone of the article at a side of the article facing away from the outfeed entry. An angle of the average direction of the diverting force of the fluid jet with the outfeed path at the outfeed entry is in the range of 5 to 85.

The present invention relates to a separator device (22) for a folder-gluer machine, the separator device being configured to divide a shingled stream of folding boxes into separate batches, the separator device comprising a vertically movable separator head and at least one upper evacuation conveyor belt.

A lower conveyor system (30) has a lower evacuation conveyor belt, such that the folding boxes are pinched between and transported by the upper evacuation conveyor belt and the lower second conveyor belt in unison.

A method for transferring a sheet in a sheet transport assembly from a supplying conveyor to a receiving conveyor. The method includes arranging a contact side of a sheet in contact with a transport belt of the supplying conveyor, advancing the sheet on the transport belt in a transport direction along a process unit, which applies a process to a process side of the sheet opposite to the contact side, and to a transfer area where the sheet is transferred to a receiving conveyor. To correct for curl deformation of the sheet, air flow is directed onto the process side of sheet, which urges the sheet towards a supporting element. The air flow is controlled in response to a curl deformation behavior of the sheet.

Examples include a machine assembly for conveying sheet-format substrates, including a first belt conveyor and a second belt conveyor. These belt conveyors each have a continuously circulating transport belt and are arranged one after another in the transport direction of the substrates conveyed on the respective transport belt. The substrate to be transferred from the first belt conveyor to the second belt conveyor is lifted off the transport belt of the first belt conveyor by means of an air current generated by a lifting nozzle and an opposing air current generated by a counter-nozzle. The substrate to be transferred remains fixed until its transfer by the vacuum pressure generated by a suction chamber of the first belt conveyor. This suction chamber fixing the substrate is arranged close to the lifting region. Examples also relate to a printing machine comprising this machine assembly.

A stacker module includes a lift table, a stacker configured to place sheets that are successively supplied thereto onto the top of a stack forming on the lift table, a controller configured to lower the lift table as the stack grows, a height-adjustable eject table, and an eject mechanism configured to transfer a completed stack from the lift table onto the eject table. The eject mechanism is height-adjustable for transferring stacks onto the eject table in different height positions of the lift table.

A sheet stacking system for transporting sheets and depositing them in a stack includes a layboy, a transport conveyor downstream of the layboy, and a main conveyor downstream of the transport conveyor, the main conveyor having a frame and being supported by a conveyor support, a discharge end of the main conveyor being movable between a lowered position and a raised position relative to the conveyor support. The main conveyor intake end is configured to move from a first position when the main conveyor discharge end is in the lowered position to a second position when the main conveyor discharge end is in the raised position, and also a variable length conveyor between the transport conveyor and the main conveyor, the variable length conveyor having a discharge end connected to and movable with the main conveyor intake end and movable relative to the transport conveyor discharge end.
