Definitions

  • the invention relates to the rotary pressure, preferably the roller pressure. It can be used with advantage in particular for working with dampening solution pressure, preferably offset printing. A typical application is newspaper printing.
  • the fan-out effect and the associated problems with regard to the print quality are known.
  • the web under tension experiences a transverse expansion or broadening, which suffers especially in multi-color printing, the print quality.
  • the phenomenon is commonly encountered with anti-fan-out devices acting on the web, such as anti-fan-out scooters or rollers.
  • the DE 35 45 270 C1 , the DE 103 41 229 A1 and the WO 88/05022 A1 called.
  • the invention is based on the idea that a web should be cut longitudinally before printing in partial webs, since the problem of transverse strain in each of the partial webs can be met more easily than with a wider original web. Across the width of an example one- or two-page-wide sub-web, the transverse strain plays a much smaller role than in a four- or six-page-wide starting web, for example.
  • the partial webs are not easily conveyed through printing gaps and printed there, but it is acted on at least one of the partial webs that extends their path between the pressure gaps relative to the web path of the other or at least one other sub-web or shortened to compensate for different elongations, which experience the partial webs between the pressure gaps, ie to compensate.
  • more easily manageable partial webs are printed in relation to the transverse strain, and these partial webs are further compensated with respect to differences in longitudinal expansion. In this way, an improved printing result with respect to transverse strain and elongation variations is obtained.
  • a rotary printing press as the invention relates, accordingly comprises a cutting device for longitudinal cutting of the web in partial webs.
  • a cutting device for longitudinal cutting of the web in partial webs.
  • four-side-wide or six-side-wide webs which are preferred examples of parent webs, can be cut longitudinally, particularly into two-page-wide or one-page-wide sub-webs or combinations of such sub-webs.
  • the rotary printing machine further comprises at least two pairs of cylinders, namely a first pair of cylinders arranged on a web path of the web or sub-webs after the cutter and forming a first printing nip for the web or sub-webs, and another cylinder pair following on the web path the first pair of cylinders is arranged and forms a further pressure gap for the web or partial webs.
  • the web or the partial webs are preferably printed with two different colors.
  • the rotary printing press further comprises a arranged on the web path between the pairs of cylinders length expansion compensator which forms a wrapping axis for at least one of the partial webs and for compensating for differences in longitudinal elongation partial webs transverse to the Umschlingungsachse is movable, so that in dependence on the Length difference difference of the track path of the respective sub-web is extended or shortened compared to the web path to the at least one other sub-web or at least one of the several other sub-webs.
  • the elongation variation is compensated so that the partial webs are printed in register in the common further printing nip with respect to the circumferential register.
  • a length expansion compensator is basically sufficient for only one of the partial webs.
  • the length expansion compensator for n-1 partial webs ever one Forming belt, which is transversely movable relative to the other Umschlingungsachsen respectively.
  • the length expansion compensator forms a single transversely movable wrapping axis for each partial web which can be obtained from the original web by means of the cutting device.
  • the length expansion compensator comprises n mechanically compensator structures movable independently of one another, ie at least n-1 and more preferably n compensator structures, each of which forms one of the wrapping axes and which are mechanically independently adjustable.
  • the at least one compensator structure of the elongation expansion compensator or preferably a plurality of compensator structures is or are preferably each cylindrical with a peripheral surface parallel to the wrapping axis or to the respective wrapping axis.
  • the wrapping axis or several wrapping axes preferably points or points parallel to the axes of rotation of the cylinder pairs.
  • the easiest way to achieve that the partial webs are preferably not offset laterally as preferred by the length expansion compensator.
  • Such a length expansion compensator acts in the manner of a cutting register adjustment device, but lays back only small travel paths for the compensation of elongation variations in comparison to the travel paths of known cutting register adjustment.
  • the at least one compensator structure or the preferred plurality of compensator structures of the elongation expansion compensator is or are preferably each looped in the current production in all operating conditions of the or the sub-webs. In principle, however, it should not be ruled out that one or more compensator structures are or will be moved out of the loop in certain operating states.
  • the length expansion compensator preferably comprises a plurality of individually adjustable compensator structures
  • the compensator structures can be moved into a position in which all the circumferential axes of the elongation expansion compensator are in alignment with one another.
  • the compensator structures in this neutral position preferably form a uniform, particularly preferably cylindrical Peripheral surface, so that the compensator for example, a non-cut web can be used simply as a guide roller.

Since the web path between the printing units is noticeably longer than the web paths in each case within the printing units, the length expansion compensator is preferably arranged between the printing units.
  • the web is printed in more than two printing nips, in principle even several elongation expansion compensators can be arranged between the several printing nips, ie in each case one elongation expansion compensator between two printing nips next to the web path. If the partial webs are successively printed, for example, in four printing gaps, this means that a total of three elongation compensators can be provided, or even only two between different printing gaps. In the usual configurations of printing nips it is however, this is completely sufficient if only one longitudinal expansion compensator is provided for the partial webs to be printed together in several printing nips, in particular in the above-described examples for the arrangement of printing units and printing units composed of several printing units. As a printing unit, in each case arranged on one side of the web or partial webs cylinders and rollers are considered.

  • a gradual taper has the advantage that even with a comparatively small wrap angle of the sub-web guided under tension ensures compliance with the axial position and wrinkling is reliably prevented.

  • transition portions forming connecting portions may be rounded in the axial direction, in particular trumpet-shaped or arched bulging outward, preferably they are straight, ie they have in a longitudinal section of the guide means obliquely toward each other and close to each other an angle of slightly less than 180 °.
  • the inclination, whether rounded or straight, is chosen so that although a certain centering effect is achieved in the direction of the receding middle section for the guided sub-web, the sub-web, on the other hand, does not experience a lateral offset, the extent of which could be relevant with regard to the page register , In this sense, the management device keeps the guided sub-lane on track.
