Definitions

  • the invention relates to a forme cylinder of a web-fed printing press, to which at least one printing form is applied. Furthermore, the invention relates to methods for operating a web-fed printing press.
  • the printing plates are mainly disposable plates, which are usually made offpress in a platesetter.
  • Such disposable printing plates in which most of the printed image is baked, are usually used in very high print runs. After printing, these disposable printing plates are thrown away.
  • the DICOWEB digital printing machine
  • plate or plate cylinders in the printing unit, which instead of the printing plates use sleeves, ie sleeve-shaped printing plates and thus manage without conventional plate tension or clamping mechanisms.
  • the sleeves, the sleeve-shaped printing plates are pushed onto the plate or plate cylinder with the aid of an air cushion.
  • the printing plate costs are becoming an ever more dominant contribution to the production costs.
  • an imaging method is known, which makes it possible to produce printing plates for smaller print runs correspondingly less expensive. Because of the, the printing process downstream erase cycle, the possible print run height is limited. The manufacturing process of these printing plates can be done both Inpress and Offpress.
  • the inventors have set themselves the task to improve a web press regardless of whether it works with digital Inpefbercisung or conventional plate.
  • the inventors have recognized that it is possible to use both conventional printing plates and Sieeves on a modified forme cylinder of a printing press and thus to draw the suitable and cost-effective printing plate onto the forme cylinder or plate cylinder without major conversion measures, regardless of the number of copies.
  • the inventors propose to improve a forme cylinder of a web-fed printing press to which at least one printing plate is applied in such a way that the forme cylinder consists of at least one cylinder core and an adapter sleeve mounted thereon, wherein the adapter sleeve is designed such that can be attached to this either printing forms in the form of sleeves or printing plates.
  • the corresponding low-cost directly imaged sleeves can be used for imprint jobs, while the correspondingly inexpensive disposable plate is used for the high-circulation component.
  • the invention allows both the use of Sieeves either as endless sleeves or as sleeves with welded seam.
  • adapter sleeves can optionally be designed without a clamping channel or with at least one clamping channel.
  • this adapter sleeve is suitable for sleeves, in the version with at least one clamping channel this is preferably suitable for printing plates. It is advantageous if several such clamping channels are arranged in adapter sleeves with clamping channel. These can preferably be offset relative to one another with respect to the circumference of the adapter sleeve.
  • the offset of the clamping channels on the adapter sleeve circumference can be 90 °, 120 ° or even 180 °.
  • a 90 ° offset of the clamping channels to each other for example, four clamping channels along the forme cylinder circumference can be mounted on the cylinder.
  • less than four clamping channels or even more than four clamping channels with 90 ° offset can be mounted on the forme cylinder.
  • the adapter sleeve consists of a metal foam and / or a plastic foam.
  • the inventors also propose a new method for operating a web press.
  • the new method is characterized in that the forme cylinder consists of at least one cylinder core and an adapter sleeve, wherein on this cylinder core adapter sleeves are applied, which are designed such that in each case printing plates in the form of sleeves or printing plates can be attached, before depending on the height of the print run, either sleeves or printing plates are attached to the adapter sleeve.
  • the new method it is intended to image the printing forms either inside or outside the printing press. Especially the illustration of the printing forms within the printing press saves an enormous amount of time.
  • FIG. 1 shows a view of an end face of an adapter sleeve 4 with attached endless sleeve 1.
  • the adapter sleeve 4 is pushed with the inner diameter 4.3 on the cylinder core of the new forme cylinder.
  • the print format can be adjusted.
  • Both inner diameter 4.3 and outer diameter 4.4 of the adapter sleeve 4 are adaptable to the cylinder core and the printing format.
  • FIG. 2 shows the adapter sleeve 4 of Figure 1, in which a welded sleeve 2 is mounted.
  • the weld seam 2.1 of the sleeve is indicated by a dot.
  • the structure of the forme cylinder 3 consists of a cylinder core 3.1, on the outer surface of the adapter sleeve 4 is pushed.
  • the adapter sleeve 4 On the adapter sleeve 4, in turn, either a sleeve can be attached or the adapter sleeve 4 is designed such that one or more conventional printing plates can be attached.
  • the adapter sleeve for example, for receiving sleeves without clamping slot and for receiving pressure plates with plate clamping slot (s) be performed.
  • FIG. 4 shows an adapter sleeve 4.2 in which the pressure plates are tensioned with the aid of the centrifugal force which is generated during rotation of the forme cylinder.
  • the clamping wedge 4.5 on the side surfaces abut the folds of the pressure plate is pressed during rotation of the forme cylinder to the outer shell area and thus holds the pressure plate firmly.
  • FIG. 5 shows a view of an end face of an adapter sleeve 4.1 with clamping slot. In clamping slot on the top of the adapter sleeve 4.1, the printing plates 5 can be attached.
