An edge portion of a bound material is provided with first and second lines. The first and second lines are spaced at a small interval and arranged in parallel to each other. The first line is arranged outside of the second line of the bound material. A control unit controls first and second drive mechanisms in such a manner that the edge portion of the bound material is cut at the first line by a trim cutter, then the trim cutter or the table is moved at the small interval in a moving direction toward the second line, and then the edge portion of the bound material is cut at the second line by the trim cutter.

A device for manufacturing a book on demand, including a cover printing or receiving station designed to respectively print or receive a cover, a body printing or receiving station designed to respectively print or receive a body, a binding station designed to join together the body and the cover, a conveyor designed and/or programmed to convey the cover and/or the body between the different stations, the device is designed to deposit glue in a gluing region on the verso of the cover inside the binding station before the cover and the body are joined together by gluing, forming a book.

A three side trimmer has a trimming unit 1, an accumulating unit 3, a discharge unit 2 and a conveying mechanism 4 conveying trimmed booklets BK to the accumulating unit. The accumulating unit has a shelf 5 movable in a vertical direction, and a drive roller conveyor 7 on the shelf. The accumulating unit, in a mode, delivers the trimmed booklets to the discharge unit at every accumulation of a predetermined number of the trimmed booklets and, in another mode, accumulates the trimmed booklets without delivering.

Processing units 4 to 6 aligned along the transport path for a sheet bundle S are accommodated in a housing together with transport units 2 and 3. Windows 10a to 10c are provided in the housing front face, and variable-color lighting units 17 are arranged inside the housing. Light emitting surfaces (projection plates 18) of the variable-color lighting units are arranged facing the windows. Sensor units 13, 15a, and 15b that detect an anomaly of an operation of the transport unit and sensor units 14 and 16 that detect an anomaly of the operation of respective processing units are provided. A binding processing unit stops when an anomaly is detected by the sensor unit, when a system error occurs, or when an emergency stop instruction is input. The color of emission light from a light emitting surface changes to indicate the operation status of the binding processing system.

A trimmer comprises a trim knife for trimming the bound material, a blade receiving portion 19 for receiving a blade edge of the trim knife, and an adjustment mechanism 60 configured to adjust a position of the blade receiving portion 19 in such a manner that each of one side 191 and other side 192 of the blade receiving portion 19 moves by not only a same amount but also a different amount and in directions toward and away from the blade edge of the trim knife. Each of positions of the one side 191 and the other side 192 of the blade receiving portion 19 can be adjusted.

A device for carrying out cutting operations on at least one open format edge of a printed product, includes: a transport unit configured to transfer the printed product along a guide path from a first cutting location to a second cutting location and from the second cutting location to a third cutting location for an edge-related cutting operation, the transport unit having at least one gripper configured to grip the printed product by its spine to convey the printed product from one cutting location to the next in a suspended manner, and at at least one cutting location, at least one cutting tool configured to perform the edge-related cutting operation comprising a first edge-related cutting operation and optionally at least one second subsequent edge-related cutting operation.

It is an object to provide a trimmer that can trim a fore-edge portion of a bound material except a cover and that can be excellent in productivity and cost. A cover has flap portions adjacent to the fore-edge portion of the bound material, a trimmer includes: a trim cutter that trims the bound material; a blade receiving portion that receives an edge of the trim cutter; a base portion and a pressure portion that nip and position the bound material; and a pair of guide portions arranged for movement in a direction close to or away from the bound material, wherein the guide portions are inserted between the book block and the cover so as to peel the cover together with the flap portions up when the fore-edge portion of the bound material is trimmed by the trim cutter.
