Abstract: A switch-over processing method includes the steps of performing a first process on a sheet passing between a first cylinder and a second cylinder with a first mounted body being mounted on a circumferential surface of the second cylinder arranged to oppose the first cylinder, and performing a second process different from the first process on the sheet passing between the first cylinder and the second cylinder with a second mounted body being mounted on a circumferential surface of the second cylinder in place of the first mounted body. A switch-over processing apparatus is also disclosed.

Abstract: A sheet processing device includes a transport cylinder, processing cylinder, and blowing device. The transport cylinder holds and conveys a sheet. The processing cylinder opposes the transport cylinder, and processes the sheet conveyed by the transport cylinder. The blowing device blows air to the sheet conveyed by the transport cylinder on an upstream side in a sheet convey direction of a contact position where the sheet conveyed by the transport cylinder comes in contact with the processing cylinder.

Abstract: A processing device includes a transport cylinder, processing cylinder, and press roller. The transport cylinder includes a hold device which holds a sheet, and a plate support device which supports a plate to be mounted on an outer surface of the counter cylinder. The processing cylinder opposes the counter cylinder and processes the sheet. The press roller is supported to be movable between an operative position and retreat position. At the operative position, the press roller is close to the outer surface of the transport cylinder. At the retreat position, the press roller separates away from the outer surface of the transport cylinder, the plate being pressed against the outer surface of the transport cylinder by the press roller.
