Definitions

  • the invention relates to methods and devices for preparing a forme cylinder and a forme cylinder according to the preamble of claims 1, 3, 5, 6 or 15.
  • DE 44 30 555 C1 and DE 38 37 909 C2 describe methods for imaging forme cylinders. Material from a transfer film is selectively applied directly to the surface of the forme cylinder at the ink-carrying points. Squeegees can be provided to remove this selectively applied material. A printing film as an intermediate carrier of the printed image is not provided.
  • the invention has for its object to provide methods and devices for printing preparation of a forme cylinder and a forme cylinder.
  • the printing form e.g. B. printing film or printing plate
  • the printing film is applied and imaged in the shortest possible time, since the imaging takes place already during the application process of the printing film.
  • the printing film is detached from the surface of the forme cylinder in a simple manner with at least one doctor blade.
  • doctoring is carried out by means of an axial reciprocating movement of the doctor device, possibly using heat.
  • a forme cylinder 01 for a rotary printing press has a feed and pressing unit 03 for printing formes 04, e.g. B. printing film 04, which is removable from a supply roll 06.
  • the printing film 04 is pulled off the supply roll 06 z. B. by means of a pair of pull rollers 07, a pressing unit 08, z. B.
  • a pressure roller 08 defines a beginning 09 and the subsequent printing film 04 on the outer surface 02 of the forme cylinder 01 during its rotational movement.
  • the printing film 04 is on its side facing the forme cylinder 01 with a z. B. provided self-adhesive adhesive layer.
  • a knock-off knife 11 ensures that the printing film 04 is separated in order to produce one end of the printing film 04 to be applied.
  • a plurality of printing film sides can be arranged one behind the other or next to one another both on the circumference and in the axial direction of the forme cylinder 01. It is also possible to apply a printing film 04 with a forme cylinder to the forme cylinder 01.
  • At least the outer surface 02 of the forme cylinder 01 can consist of smoothly polished ceramic material, plastic or also of rustproof metal.
  • the printing film 04 applied to the forme cylinder 01 is imaged by means of the imaging device 12, the printing film 04 is cleaned with a known cleaning device 13 likewise arranged on the circumference of the forme cylinder 01.
  • a squeegee device 14 which can be set on the lateral surface 02 of the forme cylinder 01 is provided, which with its working squeegee 16 at a negative angle, i.e. a H. against the direction of rotation A of the forme cylinder 01, can be adjusted to the forme cylinder 01.
  • the working squeegee 16 can advantageously be heated in the vicinity of its working edge 17. That can e.g. B. by means of an induction heating device 18 or by means of the frictional heat generated when doctoring the printing film 04.
  • doctor device 14 is arranged so that it can be moved back and forth in the axial direction of the forme cylinder 01 during the doctoring process.
  • This can be done by known means, e.g. B. a linear guide, which is connected to a cam mechanism, take place.
  • the outer surface 02 of the forme cylinder 01 can be cleaned by means of the cleaning device 13.
  • the feed and pressure unit 03, the cleaning device 13 and the doctor device 14 can each be activated and actuated either separately on the forme cylinder 01 or combined with other devices mentioned.
  • Printing film 04 is also to be understood as a sheet-shaped printing plate. Printing film 04 or printing plate carry the printed image and are attached to the outer surface of the forme cylinder 01 as a removable intermediate support for the printed image.
