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.

The trimmer includes: a pusher 2 that pushes the bound material 1; a pusher moving device that moves the pusher; a positioning part 111 that positions the bound material pushed by the pusher; an allowable position memory that memorizes an allowable position range relevant to the pusher; an allowable reaction force memory that memorizes an allowable reaction force range relevant to the pusher; and a determiner that determines whether a length of the bound material is normal or abnormal. The determiner determines that: the length L of the bound material is normal; or the length L of the bound material is abnormal.

A method is for operating a device for carrying out cutting operations on an open format edge of a printed product. The device is operatively connected to a feed apparatus for the first cutting operation and to a removal apparatus which operates after the final cutting operation. The printed product is transferred from a first cutting location, at which the cutting operation for a first format edge is carried out, to a second cutting location, at which the cutting operation for a second format edge takes place. Once the cutting operation is complete at the second cutting location, the printed product is transferred to a third cutting location, at which the cutting operation for a third format edge takes place. The printed product is transferred among the cutting locations by a transport unit that grips the printed product by the spine to convey the product in a suspended manner.

A device for carrying out cutting operations on an open format edge of a printed product is operatively connected to a feed apparatus for the first cutting operation and to a removal apparatus which operates after the final cutting operation. The device comprises a cutting apparatus configured to carry out each edge-based cutting operation. The printed product is moveable from a first cutting location, at which the cutting operation for a first format edge takes place, to a second cutting location, at which the cutting operation for a second format edge takes place, after which, the printed product is transferable to a third cutting location, at which the cutting operation for a third format edge takes place. The printed product is transferable by a transport unit having a device by which the printed product is gripped by the spine and is conveyable in a suspended manner.

A trimmer trims a bound material at end portions and/or corner portions of the bound material. The trimmer has a table (2), a pressing unit (4), a trimming mechanism (5) that has a trimming blade (52) and moves the trimming blade (52) to the trimming position, a rotation mechanism (3) that rotates the table (2), a rotation control unit that is operatively connected to the rotation mechanism (3) in such a way that a predetermined trimming line of the bound material positioned parallel to a longitudinal direction of the trimming blade (52), a moving mechanism (6) that moves the trimming mechanism (5) in a direction perpendicular to the longitudinal direction of the trimming blade (52), and a movement control unit that is operatively connected to the moving mechanism (6) so as to move the trimming mechanism and align the trimming line and the trimming position with each other.

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.

The trimmer includes: a pusher 2 that pushes the bound material 1; a pusher moving device that moves the pusher; a positioning part 111 that positions the bound material pushed by the pusher; an allowable position memory that memorizes an allowable position range relevant to the pusher; an allowable reaction force memory that memorizes an allowable reaction force range relevant to the pusher; and a determiner that determines whether a length of the bound material is normal or abnormal. The determiner determines that: the length L of the bound material is normal; or the length L of the bound material is abnormal.

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.
