A method operates a facility, which serves for the continuous production of multiple gang runs for forming individual signatures or signature packs from which type-specific print products are made in a downstream print further processing machine. An endless web is the basis for the formation of these multiple gang runs. The endless web, in the non-folded state, is imparted complementary handling by facility-internal means according to the following criteria: i) in a 2-gang run, the individual signatures or the folded signature packs are only deflected in a second longitudinal air folding station disposed downstream of the first longitudinal air folding station; and ii) in a 3 or 4-gang run, the individual signatures or the folded signature packs are additionally folded in a second longitudinal air folding station disposed downstream of the first longitudinal air folding station.

The present invention provides a sheet stacking device, a counter-ejector, and a carton former and is provided with: a hopper unit that stacks cardboard boxes; feed rollers that feed a cardboard box to the hopper unit; a first blower device that blows air from above the hopper unit toward the cardboard box fed by the feed rollers; and a second blower device that blows air between the cardboard box stacked in the hopper unit and the cardboard box fed by the feed roller.

A sheet postprocessing device includes a sheet conveying passage, a sheet tray, an inlet guide, a processing device, and a blowing device. Though the sheet conveying passage, a sheet on which an image has been formed is conveyed. The sheet tray is arranged downstream of the sheet conveying passage and has sheets stacked on it. The inlet guide is arranged at the downstream end of the sheet conveying passage and guides a sheet to the sheet tray. The processing device performs predetermined processing on a sheet stacked on the sheet tray. The blowing device blows air, from the upstream side in the sheet conveying direction, between the top face of the top-most sheet in the sheets stacked on the sheet tray and the bottom face of the subsequent sheet sent from the inlet guide into the sheet tray.

A device for overlapping sheets includes at least one blower box and a supply table. Multiple sheets are guided into a region of the blower box consecutively, in the same transport direction, and are arranged at a distance from one another on the supply table. A blower nozzle is arranged in the blower box, on the side thereof facing the supply table. A blowing direction of the blower nozzle is oriented and parallel to the supply table and against the transport direction of the sheets. The supply table is arranged below the blower box and multiple blower nozzles are arranged in the blower box, one after the other, in the transport direction of the sheets, on the side thereof facing the supply table. A respective blowing direction of the blower nozzles is oriented in parallel to the supply table, and against the transport direction of the sheets.

Please add the Abstract of the Disclosure, as set forth on the separate accompanying sheet. This Abstract of the Disclosure is essentially the same, in content, as the Abstract which is a part of the published PCT application, WO 2017/202762A1. No new matter is being presented by the addition of this Abstract of the Disclosure.

A sheet stacker includes a sheet ejector, a sheet stack portion, and air blowers. The sheet ejector ejects a sheet. The sheet stack portion stacks the sheet ejected by the sheet ejector. The air blowers blow air from blow ports toward the sheet ejected from the sheet ejector. Each of the air blowers includes an air generator, an air guide, a first blow portion, a second blow portion, and a switcher. The air generator generates the air. The air guide guides the air to each of the blow ports. The first blow portion blows the air toward the sheet. The second blow portion blows the air in a direction different from a direction in which the first blow portion blows the air. The switcher performs switching so that the air guide guides the air to one of the first blow portion and the second blow portion.

There is provided a post processing device including a mounting portion on which a medium is temporarily mounted, a post processing unit that performs post processing on the medium mounted on the mounting portion, a discharging tray on which the medium is stacked after being discharged, and a suppressing unit that suppresses deformation of the medium mounted on the mounting portion.

An assembly for entraining a cut end of a web in a fluid flow, the assembly comprising an arrangement for delivering a fluid flow proximal to an entrainment region where a web is cut. The assembly further has an arrangement for guiding the fluid flow and the entrained end of the web from the web entrainment region to a web delivery region.

An apparatus uses forced air to remove trim from cut sheets during a converting process. The apparatus may include a plurality of wheels, arranged to allow trim to fall between the wheels, and one or more air chambers, configured to propel air toward the sheets as they are conveyed on the wheels in order to remove trim from the sheets. A method may include conveying sheet stock on wheels arranged to allow trim to fall through them, and propelling air toward the sheet stock with air chambers such that trim is removed from the sheet stock by the propelled air.

A medium transport device 29, a liquid ejection device 13, and a post-process device 15 include a recording path 38; a first transport path 40 arranged downstream of the recording path 38; an inversion path 39 arranged downstream of the recording path 38; a first branch section 51; and a blower section 50 configured to transport the medium 19 to either the first transport path 40 or the inversion path 39, wherein when a medium 19 that is transported first is defined as a first medium and a medium 19 that is transported subsequently to the first medium is defined as a second medium, in a case where the blower section 50 switches a transport destination between the first medium and the second medium, the blower section 50 starts the switching operation while the first medium is passing through the first branch section 51.
