The line comprises a feed path (P) of the web material (N) and, along the feed path, a transverse cutter (5) for cutting scraps (FS) from the continuous web material (N). The line includes a system for removing scraps of web material cut by the cutter. The system for removing scraps is fitted with a scrap accumulator member (21). The accumulator member (21) is movable in a direction generally parallel to the feed path (P) of the web material between: a position for receiving scraps, wherein the distance between the accumulator member (21) and the cutter (5) is such that scraps (FS) generated by the cutter (5) are collected by the accumulator member (21); and a standby position, at a distance from the cutter (5) such that scraps (FS) generated by the cutter are collected in a space (D) between the cutter (5) and the accumulator member (21).

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 window treatment cutting tool may include a pair of cylindrical support tubes that are configured to support a roller tube assembly. The window treatment cutting tool may include a clamping assembly. The clamping assembly may be configured to abut the roller tube assembly to secure the roller tube assembly against the pair of cylindrical support tubes. The window treatment cutting tool may include a cutting arm assembly. The cutting arm assembly may include a blade support member and a blade attached to the blade support member. The blade support member may be configured to be biased toward the cylindrical support such that the blade contacts a flexible material of the roller tube assembly. The window treatment cutting tool may include an adapter that is configured to transfer rotation of a drill or hand crank to the one or more of the pair of cylindrical support tubes.

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.

A self-cleaning apparatus for sorting a mixture of materials is disclosed that comprises a material sorter and a gantry positioning system elevated above the material sorter. The gantry positioning system includes a longitudinal travel rail with a longitudinal travel rail carriage, a traverse travel rail connected to the longitudinal travel rail carriage running perpendicular to the longitudinal travel rail, a traverse travel rail carriage, and a vertical travel rail connected to the vertical travel rail carriage and running perpendicular to the traverse travel rail. A cutter and, optionally, a picker, are connected to the vertical travel rail. The gantry positioning system can move the cutter and picker in various directions to dislodge and remove material that may have accumulated on the sorter. Instead of a gantry positioning system, the apparatus may have a multi-axis arm.

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.
