A booklet making apparatus includes a pressurizing member configured to oppose a first surface of a sheet bundle, a receiving member configured to oppose a second surface of the sheet bundle opposite to the first surface and nip the sheet bundle together with the pressurizing member, a moving portion configured to move the pressurizing member to a retracted position where the pressurizing member is retracted from the sheet bundle and a pressurizing position where the pressurizing member is in contact with the sheet bundle to pressurize the sheet bundle, a heating portion configured to heat the pressurizing member, and a sheet separation member configured to come into contact with the first surface of the sheet bundle and separate the sheet bundle from the pressurizing member in a process of the pressurizing member moving from the pressurizing position to the retracted position.

A booklet making apparatus includes a heat-and-pressure bonding portion including a pressurizing member, a receiving member, a moving portion configured to move the pressurizing member, and a heating portion configured to heat the pressurizing member. The booklet making apparatus is configured to nip, heat, and pressurize, between the pressurizing member and the receiving member, a plurality of sheets on at least one of which an adhesive layer is formed, and thus make a booklet. The booklet making apparatus further includes an elastic member. A deformation amount of the elastic member is constant while the moving portion moves from a first position to a second position. In a case where the moving portion moves from the second position to a third position, the deformation amount of the elastic member increases in accordance with a movement amount the moving portion.

An image forming system includes an image forming apparatus and a sheet processing apparatus having a stacking unit, a moving unit, and a thermal compression bonding unit. The stacking unit includes a stack of plural sheet having an adhesive layer for bonding the plural sheets together. The thermal compression bonding unit includes a heating member having a heat generation area. In a case where a length of the adhesive layer regarding a longer-side direction of the heating member is greater than a length of the heat generation area, an entire area of the adhesive layer on the plural sheets is heated and pressed by applying heat and pressure to the adhesive layer more than once while changing, via the moving unit, a relative position of the plural sheets having been conveyed onto the stacking unit and the heat generation area regarding the longer-side direction of the heating member.

A perfect-bound booklet includes a sheet set that is a stack of multiple sheets and multiple adhesive layers provided at an end of each sheet in the sheet set and interposed between the sheets and peelably bonding the sheets together, the multiple adhesive layers containing a thermoplastic adhesive agent, and the amount of the thermoplastic adhesive agent in the multiple adhesive layers changes from each of a first surface side and a second surface side of the booklet toward the middle of the booklet in the thickness direction.

Systems and methods are disclosed to produce a books in which interior staples are hidden. One disclosed example apparatus includes a sensor to detect a position of a book being produced on a binding line. The example book includes signatures coupled by a fastener. The fastener separates a first signature portion from a second signature portion of a first signature. The example apparatus also includes an adhesive dispenser to dispense adhesive to at least one of on or adjacent the fastener to couple the first signature portion and the second signature portion along a first fold adjacent the fastener. The example apparatus also includes a controller to cause the adhesive dispenser to dispense adhesive based on the position of the book detected by the sensor.

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.

A sheet post-processing apparatus includes a sheet folding unit and a binding processing unit. The sheet folding unit is located along a conveyance path of a sheet to be folded and performs folding processing on the sheet to form a folded body having a fold along a direction crossing a sheet conveyance direction. The binding processing unit is located downstream of the sheet folding unit in the sheet conveyance direction and performs binding processing on the folded body to bind a lateral side of the folded body.

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.

A sheet pasting and binding apparatus has a paste application unit, an acquisition unit, a detection unit, and a controller. The paste application unit can change an application amount for applying paste to fed sheets. The acquisition unit acquires the number of printing instructed sheets. The detection unit detects the remaining amount of the paste. The controller controls the paste application unit so that pasting and binding are performed using a second paste application amount which is smaller than a first paste application amount while the pasting and binding are performed using the first paste application amount which is specified in advance as the paste application amount for maintaining a binding force between the sheets, based on the reception number and the remaining paste amount.

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.
