A system, preferably a saddle stitcher, includes: a transport chain, which is roof-shaped in an upper region, along which one or more printed products is astride transportable, collected, and are optionally stapled in an intermediate stapling station; and a stop adjustable according to a format of a printed product of the printed products, the stop being arranged in a transport direction of the printed product, behind the stapling station, and along a further course of the transport chain. The stop is in operative connection with a delivery system and an ejector that operate interdependently with each other to perform a format-stabilized discharge of the printed product in accordance with a cycle; and that the format-stabilized printed product is fed to a cutting apparatus.

Provided is an image forming apparatus configured to form an image on a sheet. A case binding apparatus is configured to cut predetermined sides of a sheet bundle formed by binding a plurality of sheets to perform bookbinding. The case binding apparatus includes a cutting-waste box configured to collect cutting waste produced by the cutting and a cutting-waste full load detection sensor configured to detect a fully loaded state of the cutting-waste box with the cutting waste collected in the cutting-waste box. When the sheet onto which the image is to be formed is not a last sheet in the sheet bundle, the image forming apparatus does not interrupt image formation processing in response to the fully loaded state of the waste box detected by the detector when an order of the sheet in the sheet bundle is smaller than a predetermined order.

A binding unit includes a pressing portion that binds a recording material bundle, which includes a first pressing portion pressing against the recording material bundle in order to bind the recording material bundle and a second pressing portion facing the first pressing portion, an extruding portion that is separately formed from the second pressing portion, and extrudes the second pressing portion toward the first pressing portion, and a driving source that drives the extruding portion, in which the extruding portion is connected to the pressing portion, the pressing portion retracts to a downstream side in a direction where a recording material enters when the recording material enters, and the driving source does not operate in conjunction with movement of the reaction of the pressing portion.

A post-processing apparatus (1) includes a first conveyance path (41), a first processing part (55), a second conveyance path (95) and a merging conveyance path (97), and the first processing part (55) includes a conveying rollers pair (80) including a first roller (81) and a second roller (83) conveying the sheet along a first direction; a first folding rollers pair (84) including the first roller (81) and a third roller (85) forming a first nip, conveying the sheet along a second direction and performing a folding processing along a first fold line; a second folding rollers pair (86) including the third roller (85) and a fourth roller (87) forming a second nip, conveying the sheet along a third direction and performing a folding processing along a second fold line; a first folding guide (89) movable to the first nip; and a second folding guide (91) movable to the second nip.

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.

An example finisher includes a first portion extending in a vertical direction, a second portion including an entrance to receive paper as a finishing process target, and a finishing unit to perform a finishing process, the second portion extending from the first portion in a lateral direction, a stacker to receive paper discharged from the finishing unit and which extends in an opposite direction to the second portion based on the first portion, and an elevation driving unit provided on the first portion to elevate the stacker in a vertical direction.

A sheet processing apparatus includes a conveying portion, a conveying path, a discharge port, a stacking portion, a manual setting portion, a binding device which binds a sheet bundle formed by the stacking portion and a sheet bundle set at the manual setting portion by a staple, a first regulating portion which regulates a position of the sheet bundle at a rear side of the apparatus in a width direction, and a second regulating portion which regulates a position of the sheet bundle in the conveying direction. The binding device is formed to be movable back and forth to a front side and the rear side of the apparatus. When a staple is replenished to the binding device, the binding device is positioned at the third position so that a cartridge of the staple is loaded into the binding device from the front side of the apparatus.
