An image forming device includes: an image former that forms an image for determining a cutting position, on a printing sheet; an image reader that reads the image formed on the printing sheet to acquire image data; and a controller that outputs data for determining a cutting position for a cutting batch which is a stack of at least two printing sheets. The controller obtains a position of the image according to the image data, calculates a representative value from the positions obtained respectively from a plurality of printing sheets in the cutting batch, and outputs data for determining the cutting position for the cutting batch according to the representative value.

A sheet processing system according to an embodiment includes a tray that supports a sheet on opposite sides of the sheet orthogonal to a conveyance direction of the sheet. The tray includes a first adjustable support and second adjustable support positioned opposite the first adjustable support in the direction orthogonal to the conveyance direction of the sheet. A skew sensor detects a skew angle of the sheet conveyed to the tray. A corner sensor detects positions of each corner on a front end in the downstream direction of the sheet conveyed to the tray. A controller controls movement of the first and second adjustable supports based on the detected skew angle and the detected positions of each corner on the front end of the sheet conveyed to the tray so that the sheet is conveyed to the tray without jamming.

Apparatus for use with a trimmer to produce a plurality of books having different trim sizes are described. In a described example, a trimmer for use with a bindery system includes a cutting surface and a first movable backstop adjacent the cutting surface to be engaged by a first book. Additionally, the trimmer includes a second movable backstop adjacent the cutting surface and spaced from the first movable backstop. The second movable backstop is to be engaged by a second book. Further, the trimmer includes a cutter movable relative to the cutting surface to cut a face of the first book to form a book having a first size and to cut a face of the second book to form a book having a second size different than the first size.

A mat board is provided and is formed of a body having outer peripheral edges and an inner window formed therein. The inner window is defined by a sloped side wall that extends peripherally around the inner window and extends from a top surface of the body to a bottom surface of the body. The sloped side wall has an exposed convex surface, wherein corners of the inner window have curvature in that the top surface of the body in each corner is curved.

Provided herein is a paper cutter, including: a paper cutter housing which includes an accommodating space for accommodating a roll of paper to be cut, where a side wall of the paper cutter housing further includes two parallel guide rails, a holding portion is arranged on an outer wall of the paper cutter housing, and a pressure direction of the holding portion is capable of being perpendicular to a plane formed by the two parallel guide rails; and a paper cutting device which is connected to the side wall of the paper cutter housing and includes a cutter assembly, where the cutter assembly includes an object picking member and a cutter, and a direction corresponding to a cutting edge of the cutter is opposite to a paper feeding direction of the paper to be cut.

A method for splitting a semi-finished product includes placement of the semi-finished product on a splitting template, and the splitting template includes at least one elevation. The method includes fixation of the semi-finished product on the splitting template, in which an area of the semi-finished product is arranged on the elevation. The method includes splitting of the semi-finished product, in which material is removed from the semi-finished product during splitting. The material removal in the area that is arranged on the elevation is greater than in an area that is not arranged on the elevation.

Provided herein is a paper cutter, including: a paper cutter housing which includes an accommodating space for accommodating a roll of paper to be cut, where a side wall of the paper cutter housing further includes two parallel guide rails, a holding portion is arranged on an outer wall of the paper cutter housing, and a pressure direction of the holding portion is capable of being perpendicular to a plane formed by the two parallel guide rails; and a paper cutting device which is connected to the side wall of the paper cutter housing and includes a cutter assembly, where the cutter assembly includes an object picking member and a cutter, and a direction corresponding to a cutting edge of the cutter is opposite to a paper feeding direction of the paper to be cut.

There is disclosed a cutting mechanism for severing elongate fibre reinforcement material in composite material lay-up equipment, the cutting mechanism comprising a cutting element and a counteracting element which cooperate to sever fibre reinforcement material extending through the nip between them, the cutting element being mounted on an elongate arm which is pivotable about a pivot axis A spaced from the nip, to displace the cutting element relatively to the counteracting element to perform a cutting stroke, the mechanism further comprising guide means arranged to guide the fibre reinforcement material through the nip in a feed direction transverse to the pivot axis A, and an actuation device for driving the elongate arm in a cutting stroke, the actuation device acting on the elongate arm at a position away from the cutting element. There is also provided composite material lay-up equipment comprising the cutting mechanism.

A printing apparatus includes a printing portion that performs printing on a medium, a cutting portion that is capable of moving in a movement direction and that has cutting blades that cut the medium and a housing unit that holds the cutting blades, and a contact portion provided at a position at which the contact portion comes into contact with the housing unit when the cutting portion moves in the movement direction.

A recording paper cutting device enables cutting of a boundary between a first area of a recording paper and a second area of the recording paper placed at an upstream side of the first area, so that the first area is separately discharged from the second area after the first area is printed. The recording paper cutting device includes first and second cutting parts. The first cutting part of the second cutting parts moves in an approaching or departing direction so that the boundary is cut. The first cutting part includes a first cutting surface inclined by a first angle in the departing direction from the second cutting part and a second cutting surface that extends from the first cutting surface and is inclined by a second angle, which is smaller than the first angle, in the departing direction from the second cutting part.
