A cutting apparatus includes a blade configured to cut a sheet that is conveyed along a sheet conveyance path, a scrap path through which scrap generated when the sheet is cut by the blade passes, a guide member configured to guide the sheet conveyed, and a blowing unit configured to blow air such that the air crosses the sheet conveyance path from a side opposite the scrap path with the sheet conveyance path therebetween, wherein the blowing unit blows air such that the air flows along the guide member positioned at a second position at which the scrap is allowed to enter the scrap path.

A cardboard box dividing device includes lower conveyors on which a plurality of connected cardboard box bodies are stacked and transported; a pressing device pressing, from above, the plurality of connected cardboard box bodies stacked on the lower conveyors; a cutting blade disposed along a width direction of the connected cardboard box body and dividing the plurality of connected cardboard box bodies stacked on the lower conveyors into a front part and a rear part; a lifting/lowering device relatively moving the plurality of connected cardboard box bodies on the lower conveyors and the cutting blade along an up-down direction; and a control device controlling the pressing device based on a lifting/lowering height of a loading upper conveyor at a time when a pressing reaction force at a time when the loading upper conveyor presses the plurality of stacked connected cardboard box bodies reaches a preset reference pressing reaction force.

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.

A print finishing machine has a die and a drive mechanism. The drive mechanism is driven by a motor and the drive mechanism is configured to drive a stack of sheets of material through the die in order to cut the stack according to the shape of the die.

A cardboard box dividing device and a cardboard box production device include: lower conveyors on which a plurality of connected cardboard box bodies are stacked and transported; upper conveyors disposed so as to face the lower conveyors from above and supporting upper portions of the plurality of stacked connected cardboard box bodies; a pressing device pressing, from above, the plurality of connected cardboard box bodies stacked on the lower conveyors; a cutting knife disposed along a width direction of the connected cardboard box body and dividing the plurality of connected cardboard box bodies stacked on the lower conveyors into a front part and a rear part; and a lifting/lowering device relatively moving the cutting knife and the plurality of connected cardboard box bodies on the lower conveyors along an up-down direction.
