An image forming apparatus includes an image forming portion, a fixing portion configured to perform a fixing process in which the fixing portion fixes the image and the powder adhesive to the sheet, and a bonding portion configured to perform a bonding process in which the bonding portion bonds the plurality of sheets to each other with the powder adhesive by using the heating member to heat and press the plurality of sheets, wherein P1<P2 is satisfied, where P1 (MPa) is a peak value of pressure received by the sheet in the fixing process, and P2 (MPa) is a peak value of pressure received by the sheet in the bonding process.

A brochure is made by folding a single sheet of paper along a plurality of parallel longitudinal fold lines to make an interim piece. The interim piece is conveyed in the direction of the longitudinal fold lines, and folded in a right-angle direction transverse to the first direction, along transverse fold lines perpendicular to the longitudinal fold lines. A pouch is placed inside of the interim piece without adhesive, as the interim piece is folded, and the interim piece is sealed to complete the brochure. The pouch is preferably placed over one of the transverse fold lines. A label can be applied to the brochure if desired.

A method for processing a sheet for bookbinding includes operations. A cut is formed that divides a thickness of the sheet in a binding-side side surface of the sheet. A portion of a connection piece that is attached to the sheet is inserted into the cut as an inserted portion, and functions as a hinge in a book-bound state. The portion of the connection piece inserted into the cut is joined to the sheet.

A method for bringing together a wrapper and a plurality of inserts can be used to form an advertising means compilation. In a region of a compilation section, the wrapper and the inserts are deposited on one another individually and in succession on a conveying element which is moved in a direction of transport. A leading edge of the wrapper is deposited offset relative to leading edges of the inserts so as to form an excess length of the wrapper. The inserts are deposited on one another, forming a stack, such that the leading edges of the inserts form a common fold edge. The excess length of the wrapper, which lies flat on the conveying element or on the stack of inserts, is folded around the fold edge and, at least in part, around the stack of inserts so as to form the advertising means compilation.

A system for personalized printing, paper and paperboard processing, and binding to enable automatic management of simple, special, and mixed operations of paper and paperboard processing and binding, has the particular feature of being of a modular type and hence with high flexibility of use and operation in so far as into the system there may be inserted manufacturing machines or processing stations that can be allocated therein according to the desired modalities, number, and operating sequence, with the additional possibility of their being replaced with further machines different therefrom so as to obtain a system for personalized printing, paper and paperboard processing, and binding that is completely personalizable, with the maximum flexibility of use and operation according to the needs at the moment of production.

Disclosed is a binding folder for binding a bundle of leaves, whereby this binding folder essentially includes a spine for enclosing an edge of the bundle of leaves and two cover sheets attached to the spine, at least one of which is made of a synthetic material. At least one cover sheet is provided with a top sheet against the side of the cover sheet oriented towards the inside of the binding folder, whereby this top sheet is attached to the cover sheet and/or spine in a removable way.

A first press unit 2 presses each of a plurality of signatures S along a fold f, the signatures being supplied one at a time with the fold facing forward. The unit is arranged a signature conveyance unit 3 that conveys each signature received from the first press unit while controlling the attitude to make the fold orthogonal to the conveyance direction. The unit is arranged a gluing unit 4 that applies glue to both lateral edges of a top surface of each signature received from the signature conveyance unit. The unit is arranged an accumulation unit 5 that sequentially stacks the signatures received from the gluing unit on one another while jogging the stacked signatures to form a book block B. The unit is arranged a second press unit 6 that discharges the book block received from the accumulation unit after pressing the same along the folds.

Provided is a lay-flat book block production apparatus. The apparatus comprises a glue dispenser, the glue dispenser to transition between an active state in which glue is to be provided to one side of the web which is to be guided past the glue dispenser and an inactive state in which glue is not to be provided to the web which is to be guided past the glue dispenser. The apparatus further comprises a folding unit, wherein the folding unit is to fold the web along a plurality of crease lines wherein each of a plurality of flat portions of a side of the folded web faces another of the plurality of flat portions of a same side.

The invention is directed to a method for producing printed products, in particular softcover books, with integrated cover, where method includes at least the steps: printing of paper web or individually supplied paper sheets, preferably by means of digital printing; single or multiple folding and cutting of paper web to form signatures or else single or multiple folding of paper sheets to form signatures; stacking of signatures to form signature stack with at least one top and one bottom signature; folding open top sheet of top signature or else bottom sheet of bottom signature and applying an adhesive layer in at least area of folded-open sheet, which is intended to include at least spine and/or an area of signature stack adjacent to spine; and turning over sheet folded open and provided with adhesive layer around spine of signature stack, so that cover for printed product is formed.
