A recording medium processing apparatus includes first teeth that are used for binding processing of a recording medium bundle; second teeth that move toward the first teeth and press the recording medium bundle located between the first teeth and the second teeth; a position detection unit that detects a position of the second teeth; and a control unit that controls movement of the second teeth on the basis of the position detected by the position detection unit.

MACHINE AND METHOD FOR EMBOSSING PAPER WEB PRODUCTS
20230146893 · 2023-05-11 · ·

A machine for embossing, including at least one pair of embossing nips for plies of paper, at least one laminating nip to bond the plies of paper, a pair of embossing cylinders, each having on its surface a respective plurality of embossing protrusions, each defining a wrap angle for the at least one ply of paper, and defining therebetween a transfer nip, a pair of pressure cylinders, each associated with a respective one of the embossing cylinder, the embossing nip being defined between each pair formed of embossing cylinder and pressure cylinder, a laminating device for bonding the plies delivered from the transfer nip, at least one distribution device of material to facilitate ply-bonding arranged upstream of the laminating device, and at least one heating device for at least one of the embossing cylinders.

METHOD AND DEVICE FOR PRODUCING PARTIALLY EMBOSSED BLANKS

A method for producing partially embossed blanks is disclosed. The method is to provide a continuous web of an embossable material, and guide it between two cylinders which emboss its surface. The embossed web is fed to a stamping device to punch blanks from the web. One of the embossing cylinders has a marking which is readable by a first sensor. The first sensor reads the position of the marking and produces a signal which triggers a printing device to produce a print mark on the web identifying the position of the embossing. The print mark is read by a second sensor which produces a signal for controlling and adjusting a feeding distance by which feed rolls supply the web to the stamping device that punches blanks from the web in register with the partial embossing of the blank. A device for conducting the method is also disclosed.

Device for embossing and/or perforating foils for tobacco goods
09809927 · 2017-11-07 · ·

The device for embossing and perforating foils for tobacco goods includes: a pair of embossing rolls, one of the embossing rolls having teeth for perforating the foil, the counter roll to the embossing roll with the perforating teeth being a matrix roll which has recesses that correspond to the teeth on the patrix roll, both embossing rolls being arranged in a perforation device, and the device being designed in order to be operated directly or indirectly online in a machine for producing tobacco goods. The use of patrix-matrix embossing rolls allows for a large variety of perforations, the device having a control unit designed to control the exact position, size and arrangement of the perforations on the basis of the quality of the foil to be processed.

Embossing system
11084243 · 2021-08-10 · ·

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.

Binding apparatus and image forming system including same
11130308 · 2021-09-28 · ·

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.

Image forming apparatus

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.

Folding machine for forming folded paper handkerchiefs
10870252 · 2020-12-22 · ·

A folding machine for paper handkerchiefs is disclosed. The folding machine includes a longitudinal folding unit and a transverse folding unit, wherein the longitudinal folding unit executes a longitudinal folding procedure to a paper web to obtain a paper web with longitudinal folds, and the transverse folding unit receives the paper web with longitudinal folds from the longitudinal folding unit and cuts it into paper handkerchiefs before executing a transverse folding procedure to the paper handkerchiefs, thereby completing the folding process for paper handkerchiefs. After being folded longitudinally and transversely, the paper handkerchief is effectively reduced in size for packaging and is convenient for users to carry.
