A sheet processing apparatus laminates a partially joined two-ply sheet and a sheet medium inserted in the two-ply sheet. The sheet processing apparatus includes a heat presser, an information acquisition device, and control circuitry. The heat presser heats and presses the two-ply sheet and the sheet medium. The information acquisition device acquires information on the two-ply sheet and the sheet medium. The control circuitry sets a fixing temperature of the heat presser in accordance with the information of the two-ply sheet and the sheet medium acquired by the information acquisition device.

An image forming apparatus capable of transmitting paper attribute information set during job interruption. The image forming apparatus, which has an image forming device and a paper feeding part storing paper and is communicable with a management server, holds paper attribute information in association with the paper feeding part, executes an image forming job that causes the image forming device to perform a series of image forming using the paper stored in the paper feeding part, generates an execution log of the image forming job based on the attribute information, and when the attribute information corresponding to the paper feeding part is changed during the execution of the image forming job, generates an execution log including the attribute information before/after the change and transmits the generated execution log to the management server.

A converting machine is used to convert sheet material into packaging templates for assembly into boxes or other packaging. The converting machine includes a converting assembly that performs transverse conversion functions and longitudinal conversion functions on the sheet material to create the packaging templates. A fanfold crease sensing mechanism detects the presence and location of fanfold creases in the sheet material. Based on the location of the fanfold creases, the fanfold creases are either cut out of the sheet material, or the sheet material is cut to adjust the position of the fanfold crease in a packaging template.

A device for processing of flat elements, especially for the processing of paper blanks, is described. This device comprises a conveyor belt (25) that is guided over a first roller (12a) and a second roller (12b), said conveyor belt being made of metal and being permeable to air, wherein its upper section forms the transport section (25a) and its lower section forms the return section (25b), and a vacuum generator being located under the upper section of the conveyor belt. A laser (30) for cutting the flat elements is located above the transport section (25a). In order to achieve an improved flatness and an increased durability, the conveyor belt (25) consists of an expanded metal.

A sheet processing apparatus includes a plurality of folding devices, a control unit that controls a job involving a folding process, and an input unit that accepts settings for the job from a user. The input unit accepts, from the user, specification of a priority preference out of a plurality of predetermined preferences related to the folding process. The control unit selects, out of the plurality of folding devices, a folding device that can perform the folding process with the settings for the job made by the user as a target folding device. If a plurality of target folding devices are present, then based on the priority preference, the control unit determines, out of the plurality of target folding devices, a folding device with which to perform the folding process.

An image forming apparatus includes a paper discharging tray and a paper detection part disposed at an upstream end of the paper discharging tray in a paper discharge direction. The paper detection part includes a base end member provided rotatably around a first axis extending in a direction perpendicular to a paper discharge direction and a tip member pivoted to the base end member to rotate around a second axis parallel to the first axis, and extending downwardly to incline toward an upstream side of the paper discharge direction in a state where the base end member is not subjected to pressure from the paper being discharged. The base end member is disposed to face a discharge opening when being at the reference position, and the image forming apparatus stops discharging paper from the discharge opening when the base end member rotates by a predetermined threshold or more with respect to the reference position.

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.
