Abstract:
The invention concerns a digital printing machine for sheet printing with a digital printing mechanism with free format in the peripheral direction, an intermediate cylinder which is connected downstream of the digital printing mechanism and is at least partially coated with an elastic material, and a counterpressure cylinder which is connected downstream of the intermediate cylinder, wherein the counterpressure cylinder has grippers holding the sheet and the intermediate cylinder periphery is provided with recesses for receiving the grippers.

Abstract:
A device for enhancing and processing printed cardboard, cardboard packaging, paperboard, paper or similar substrates (2), especially designed for a rotational stamping process, wherein the substrate (2) can be introduced in between two rotating processing cylinders (4, 5) in an advance direction (A) and is processed as it passes there through by tool parts (7, 8) acting in a working gap (6). The inventive device (1; 1′; 1″; 1′″) is provided with a processing cylinder (4) having at least one gripper (9) for register-controlled conveyance of the substrate (2).
Abstract:
A machine for sheet-fed rotary printing or sheet coating has a sheet gripper system, an upstream feed system, and an upstream feeder. A surface refinement station for the sheet is disposed downstream of the feeder and upstream of a transfer of the sheet to the sheet gripper system.
Abstract:
The invention concerns a digital printing machine for direct non-contact sheet printing with a digital printing mechanism with free format in the peripheral direction, and a sheet transport system which is connected downstream of the digital printing mechanism, wherein the sheet transport system has grippers at its periphery holding the sheet. Counterimpression cylinders can be integrated between the sections of transport belts for conventional printing.
Abstract:
A satellite printing machine for printing sheets includes a single central common counter-pressure cylinder and at least four satellite printing groups arranged in a peripherally distributed manner about the counter-pressure cylinder in a rotational direction thereof from a feed cylinder to an output cylinder. The counter-pressure cylinder is provided in the form of a rubber blanket cylinder. At least one additional satellite printing group cooperates with the counter-pressure cylinder for at least single-color back side printing, and is disposed in the rotational direction of the counter-pressure cylinder before the feed system and after the output cylinder.
