  • Publication number: 20100188468
    Abstract: An apparatus for imprinting a sheet web includes two cylinders that rotate with a circumferential speed that corresponds to the speed of the web and which support the web over a specified angle region. Contactless printing heads are arranged side by side and at a distance to the circumferential surface of the associated cylinder and positioned transverse to the rotational direction of the associated cylinder. The printing heads each have a face oriented tangential to the associated cylinder and a center line that is essentially radial to the circumferential surface of the associated cylinder. A guiding device includes first and second guide devices associated with the respective cylinders to guide the web. Each guide device includes at least one pressure roller that fits against the surface of the associated cylinder and an element arranged to pull the web tangentially from the circumferential surface of the associated cylinder along a tangential path section.

  • Patent number: 7059598
    Abstract: A conveying arrangement for sheet quires, includes at least two successively arranged conveying devices of which a front conveying device as seen in a conveying direction has a lower speed than a rear conveying device. At least one ionization device electrostatically charges the sheet quires. An area of the front conveying device includes a suction device for administering suction air to the sheet quires in at least one region of the sheet quires.

  • Patent number: 6945529
    Abstract: A conveying arrangement for sheet quires includes successively arranged conveying devices of which a downstream conveying device as seen in a conveying direction has a lower speed than an upstream conveying device and at least one ionization device for electrostatic charging of the sheet quires. The downstream conveying device includes a suction device for administering suction air to the sheet quires at stationary suction openings.
