The invention relates to a sheet guide element for use in an apparatus for transporting sheets by means of a gripper system having at least two grippers spaced apart from each other and a sheet guide surface defined by the sheet guide element. Here, the sheet guide element is provided with depressions in the sheet guide surface, running parallel to the transport direction, at least in some sections, in order at least partially to accommodate the grippers, so that the sheet guide surface described by the sheet guide element in the transport direction runs, at least in some sections, at the same height as the movement path of the sheet leading edge fixed in the gripper system.

There is provided a recording medium discharging apparatus including: a support tray; a discharging mechanism configured to discharge the recording media; a detector configured to detect a specific state in which a position of an uppermost surface of the recording media is not lower than a predetermined position; and a controller configured to control the discharging mechanism. When executing a job for continuously discharging the recording media on the support tray at a predetermined discharge interval, the controller is configured to control the discharging mechanism to pause discharge of the recording media on the support tray under a condition that the detector keeps detecting the specific state until a predetermined number of pieces of the recording medium is discharged on the support tray since the detector has detected the specific state, and is configured to set the predetermined number to be greater as the discharge interval is shorter.

A device (1) for conveying sheet documents between upstream and downstream sheet document processors is disclosed. The device (1) is independent from the upstream and downstream sheet document processors and comprises a receiving section (4) adapted to receive, in use, sheet documents discharged by the upstream sheet document processor into an output pocket of the upstream sheet document processor, and a transport (7, 8) extending from the receiving section (4) to an output section (26). The transport (7, 8) is adapted to convey sheet documents received at the receiving section (4) to the output section (26). The sheet documents are then discharged from the output section (26), in use, to the downstream sheet document processor. A corresponding method is also disclosed.

Bank notes arriving from a control machine are fed along a feed pipe which has a plurality of outfeeds, each connected to an infeed zone of a forming channel along which an accompanying element moves, equipped with a surface on which the bank notes are rested, on top of one another, by a rotary drum located between each outfeed and the respective infeed zone, forming an ordered stack. Close to the infeed zone each forming channel has a shielding wall which is mobile between a non-operating position in which the infeed zone is open, and a position in which the latter is partially closed, limiting the inflows of air which facilitate bank note feed along the pipe and the inflows of air generated by rotation of the drum. A vibrating plate on a side wall of the channel and close to the infeed zone of the channel facilitates correct bank note stacking.

A feeder for a sheet-fed printing press includes a feeding table having a surface which, at least in subregions thereof, is formed with through openings, over which sheets separable or singlable by a suction head are transportable against lays for aligning the sheets and through which air feedable under the sheet in the region of the suction head is dischargeable in a downward direction, the feeding-table surface having edge portions formed with a respective inclination, the edge portions defining the openings.

In a delivery section of a sheet-fed printing press convertible between single-sided sheet printing and first-form and perfector printing, a sheet guide is provided formed with a sheet guide surface alterable between conditions wherein the surface is formed with throughholes and the surface is continuous and smooth, and a device for altering the sheet guide surface so that it is formed with throughholes when converting the press from first-form and perfector printing to single-sided sheet printing, and for altering the sheet guide surface so that it is continuous and smooth when converting the press from single-sided sheet printing to first-form and perfector printing.

A system for delivery and stacking sheets of paper into a receiving tray or chute from a processing machine, such as a printing machine and the like, includes supporting flanges at the open end of the chute for supporting the side edges of the paper and an air jet system vertically above the paper for bending the paper about its axis for longitudinal support of the paper to prevent roll and tumble of the sheet into the chute.

In a winding arrangement for material in sheet form, a radially displaceable box-like structure extending over the entire width of the sheet form material is arranged over the roll of material, being provided underneath with openings through which issues an airstream which is directed onto the surface of the roll and which keeps the box-like structure afloat on the lines of an air cushion. In this way, the sheeting is applied uniformly to the roll, especially in the case of thin sheeting, so that creasing is avoided.
摘要:
Sheets conveyed to a loading tray are stacked on the loading tray while they are sequentially aligned with an aligning unit, then, when pressing processing is performed with respect to a bundle of the stacked sheets, a presser is moved downward in a state where ends of the sheet bundle are abutting-held with the aligning unit. The sheet bundle is aligned by performing the pressing with a presser member gradually from a first reference fence side, to gradually discharge air staying in the sheet bundle from a first elastic body fence side.
