A device for alignment of a book block consisting of single sheets and/or signatures is useable in a processing machine, in which manufacturing of books or printed products is carried out. The device is arranged upstream of a first processing station within the processing machine. The book block is feedable directly or indirectly into the device automatically or by hand. An alignment station has a base plate with a substantially vertically extending stop surface at an end thereof. The base plate has a movable part configured to carry out a movement with respect to the stop surface such that the movement of the movable part, in an operative connection to the stop surface, brings about an alignment of the single sheets and/or signatures at a book block edge, and such that, following alignment, the book block is grippable by at least one transport clamp for processing.

An image forming apparatus, which is connectable to a first device configured to conduct a punching process on a sheet with use of a replaceable punching member, the first device being connectable to a second device configured to conduct a binding process for generating a bookbinding product having a binding member inserted through a hole punched in the sheet, the image forming apparatus including: a display configured to display a print setting screen; and a controller configured to determine whether or not the replaceable punching member of the first device is compatible with the binding member of the second device, and control the display to inhibit bookbinding setting using the second device from being selected on the print setting screen in a case where the replaceable punching member is not compatible with the binding member.

Personalized printed products are produced in which at least one individually printed sheet is combined with conventionally printed sheets. A plurality of stacks of conventionally printed sheets are made available. In addition, a print material web is made available that contains individual sheet segments and respectively one marking based on information received from a database, or a roll is provided which contains a pre-printed material web containing the sheets segments with respective markings. The markings on the individual sheet segments are read out and information read from the markings is used for selective gathering of conventionally printed sheets that are needed for the personalize printed product. Following the readout of the markings, individually printed sheets are cut from the print material web. Respectively at least one individually printed sheet is supplied to the associated, conventionally printed sheets, corresponding to the information read from the marking from the one individually printed sheet.

An image forming apparatus includes an image forming unit to form an image on a sheet, an intermediate processing tray where sheets conveyed through a first conveyance path are stacked as a sheet bundle, a sensor disposed at a second conveyance path to detect a conveyed sheet bundle, and a stacking tray in which sheets discharged through a discharging path diverging from the first conveyance path are stacked. In response to a sensor detected paper jam, a control unit determines the intermediate processing tray as the discharging destination for a sheet among the remaining sheets, and determines the stacking tray as the discharging destination for a sheet among the remaining sheets. After the paper jam is cleared, the control unit causes execution of bookbinding and cutting for a sheet bundle including the remaining sheets stacked in the intermediate processing tray.

A sheet processing device that bonds sheets to one another and then folds a resultant sheet bundle. The sheet processing device includes a stacker section that sequentially stores sheets moved thereto, an adhesive-binding unit that applies an adhesive onto sheets sequentially stored in the stacker section one by one in a sheet moving direction to bond the sheets to one another, a moving member that moves the sheets to an application position of the adhesive-binding unit, and a folding processing section that folds a sheet bundle formed by the bonded sheets at a predetermined folding position. When the number of sheets to be bonded by the adhesive-binding unit applying the adhesive onto the sheets exceeds a predetermined number, the adhesive is applied at two positions separated from each other across the folding position.

A bookbinding system shapes a booklet in such a manner that a paper sheet bundle composed of plural text paper sheets is bound by case binding using a cover paper sheet. In this case, a paper sheet having a size fitting within a region configured with a front surface, a back surface, and a spine of the paper sheet bundle is used as the cover paper sheet. For example, vertically-long A4 paper sheets are used as the text paper sheets, and a horizontally-long A3 paper sheet is used as the cover paper sheet to carry out case bookbinding. The cover paper sheet does not protrude from the outer shape of the paper sheet bundle. Thus, it is not necessary to cut the cover paper sheet, and no cutting waste is generated.

A sheet binding device includes a first tooth-shaped member that has plural arranged teeth, and a second tooth-shaped member that has plural arranged teeth, bites the first tooth-shaped member to clamp and bind sheets in cooperation with the first tooth-shaped member, and is tilted relative to the first tooth-shaped member from a beginning of biting to a completion of biting.
