A binding apparatus includes a pair of pressing members to sandwich and press a sheet bundle to bind the sheet bundle, a rotator to rotate to periodically separate and contact the pressing members with each other, a detector to detect whether the rotator is between a first position at which the pressing members are separated from each other and a second position downstream from the first position in a forward rotation direction of the rotator, and control circuitry. The second position is upstream in the forward rotation direction from a peak position at which a pressing force between the pressing members is maximum. The control circuitry is configured to rotate the rotator in a reverse direction to the forward rotation direction to move the rotator to the first position when the detector detects that the rotator is between the first position and the second position in the forward rotation direction.

An embossing apparatus which forms an emboss pattern on a sheet-type workpiece using a template sheet with the emboss pattern cut out therefrom, the embossing apparatus comprising: a mounting unit on which both a cutter member for cutting and an embossing pen for embossing are mounted simultaneously or one of the cutter member and the embossing pen is mounted alternatively; a holding member configured to hold the template sheet and the workpiece; a transfer mechanism configured to move the holding member and the mounting unit relative to each other; and a controller configured to control the transfer mechanism, the controller being configured to control the embossing apparatus to: specify the emboss pattern, cut the specified emboss pattern out of the template sheet held by the holding member using the cutter member mounted on the mounting unit by controlling the transfer mechanism, and press part of the workpiece which corresponds to a cutting region cut out, using the embossing pen mounted on the mounting unit by controlling the transfer mechanism, the workpiece being placed on the template sheet held by the holding member.

An image forming apparatus includes: a needleless binding device configured to form a recessed or raised impression as a needleless binding part by performing needleless binding on a bundle of sheets; an environment sensor; and a controller configured to perform, based on a value detected by the environment sensor, control to display a confirmation image requesting a user to make confirmation on the needleless binding prior to execution of the needleless binding.

The invention relates to an apparatus and method for cutting, printing or embossing a continuous sheet of material. The apparatus comprises a tool element, at least two anvils, which are co-operable with the tool element, and a phase adjustment device. The tool element is configured to have a constant surface speed during operation of the apparatus. The apparatus is adapted to receive the continuous sheet at a constant speed into the apparatus, and being adapted to output the continuous sheet at a constant speed from the apparatus. The phase adjustment device is operable to adjust a speed of the continuous sheet within the apparatus in order to adjust a phase of alternate parts of the continuous sheet to be cut, printed or embossed by each anvil as it co-operates with the tool element.

Rolls of an embosser laminator unit may be calibrated with an iterative process of moving axial ends of the roll a set incremental distance until contact between the rolls is made and then making a correction to the distance based upon the end of the roll making contact. The rolls may be move an initial position where the faces of the rolls are devoid of contact with each other. One or both of the rolls may be rotated. The distance between the ends of the rolls may be decreased until the faces of the rolls make contact with each other. The distance between the first ends of the rolls may be increased by an incremental amount, and a determination of contact between the faces of the rolls may be made by alternate movement of the rolls by the incremental amount and position prior to contact.

An embossing system including: an embossing unit with at least one embossing roller arranged to emboss a web of paper intended to be joined with a further web by gluing; and a gluing unit associated with the embossing unit, with a tank containing the glue used to perform the gluing and a glue dispensing device including a cliche roller adapted to distribute by contact the glue contained in the tank on one of the webs while the embossing is performed, the cliche roller rotating with a pre-fixed angular velocity around an axis parallel to said at least one embossing roller. The system further includes: a sensor to produce electrical signals having amplitude and/or frequency related to the vibrations at which the cliche roll is instantaneously subject.

An image forming apparatus includes: a needleless binding device configured to form a recessed or raised impression as a needleless binding part by performing needleless binding on a bundle of sheets; an environment sensor; and a controller configured to perform, based on a value detected by the environment sensor, control to display a confirmation image requesting a user to make confirmation on the needleless binding prior to execution of the needleless binding.

Calender for treating web materials, comprising a structure for supporting two heated rollers forming a nip, wherein each roller has surface reliefs (RR) and in an operational setting of the calender the reliefs of one roller are radially opposed to those of the other roller, each roller rotates with a predetermined angular speed around its axis, the rollers are heated by heating means, and each roller undergoes an axial elongation as a consequence of its heating. The calender comprises detection means (E1, E2; IS) adapted to detect the axial elongation of each roller and a programmable control unit (UCP) connected to the detection means and to the heating means. The control unit is programmed to determine the difference between the axial elongations of the rollers and emitting an alarm signal if the absolute value of this difference is greater than a limit value.

There is provided a sheet post-processing apparatus capable of performing eco-stapling processing to prevent a decrease in binding force by the thickness of a sheet with a simple arrangement by changing a stapling count depending on the grammage and size of a sheet and the number of sheets in consideration of the change in binding force caused by the sheet size.
