Definitions

  • a UV dryer for use, these dryers depending on the arrangement of the pressure points, individually or in combination can be installed in a housing.
  • a UV dryer for use, these dryers depending on the arrangement of the pressure points, individually or in combination can be installed in a housing.
  • FIGS. 1 and 2 the two driers (11) and (12) for serial drying of two web sides of a web in separate casings, while the driers (13) and (14) in the application for parallel drying of two web sides of a web according to Figures 3 and 4 compact housed in a housing.
  • this is a proven and economical construction method.
  • FIGS. 1 and 2 is ever a printing tower 3 and 7, consisting of two satellite printing units 5 and 6 for 4/0 and 0/4 color printing shown.
  • the unwound from a roll changer 1 web B 1 passes a dryer 11 and after the 0 / 4- or re-printing by the printing unit 6 another dryer 11.
  • the dryer 11 are ever the same side of the web B 1 faces next to the printing tower 3 or 7 is another printing tower 4, which in the embodiments of the FIGS. 1 and 2 each executed the same.
  • a second web B 2 which unwinds from another reel splitter 2 , is printed in the lower satellite printing unit 5 in the 4/0 and in the upper satellite printing unit 6 in the 0/4 color print.
  • the web B 2 is an open paper with an adequate oil permeability through appropriate porosity and roughness, so that the web B 2 can dry by knocking off, ie in the cold set.
  • the printing tower 4 is a 4/4-color printing tower which is customary in newspaper printing.
  • the webs B 1 and B 2 are further processed in a known manner to a newspaper copy.
  • the webs B 1 and B 2 or partial webs obtained by longitudinal cutting of the webs B 1 and B 2 , wherein the sub-webs can be formed after or preferably already before printing are combined by turning operations in a turning region 15 to form one or more web strands and one or more Lekssfalz Roaden, preferably Leksfalztrichter, promoted and thereby folded, cut in a folder 16 transverse to the direction of web travel and folded and finally designed as a newspaper copies.
  • the cylinders of the printing units may in particular be 4- or 6-pages wide.
  • the web B 2 is of a paper quality known in newspaper offset printing
  • the web B 1 is a much smoother, preferably calendered, and gloss-coated paper web for high gloss printing.
  • the dryer 11 are in the embodiment of FIG. 1 arranged in the printing tower 3 between the printing units 5 and 6.
  • the web B 1 thus runs on a very short path from the lower printing unit 5 through the first dryer 11, then through the four printing nips of the printing unit 6 and from there on short paths back down and through the second dryer 11, the dryer 11 are with respect to the horizontal in complete or almost complete overlap to the printing units 5 and 6 arranged.
  • Behind the second dryer 11, the web B1 leaves the printing tower 3 and runs to the turning area 15.
  • the web B 1 as already mentioned behind the reel changer and before the printing unit 5 in a plurality of sub-webs, for example two or three partial webs are cut longitudinally, which run side by side the printing tower 3 with the integrated dryer system from the dryers 11.
  • the two dryers 11 are inclined to the vertical, so that the web B 1 or the partial webs previously formed therefrom passes through or passes through the dryers 11 in a straight path and in accordance with the inclination of the dryer 11 with an inclination to the vertical.
  • the web B 1 or the sub-webs are non-contactly dried by heat or preferably by a combined radiation and heat or even more preferably by pure radiation.
  • the first dryer 11 is preceded by a guide element, for example, a guide roller and a further guide element, for example, a guide roller downstream.
  • the guide elements are arranged on the non-printed in the printing unit 5 side of the web B 1 . Between the upstream and the downstream guide element no further, the web-contacting elements are arranged.
  • the second dryer 11, such a guide element is only downstream.
  • the web B 1 or the sub-webs formed therefrom are accordingly guided by the last printing nip of the printing unit 6 in a straight path without contact through the second dryer 11 and deflected via the downstream guide element.
  • the downstream guide element is arranged on the side of the web B 1 , which has already been dried in the first dryer 11.
  • the printing press of the FIG. 2 differs from the printing press of the FIG. 1 only by the arrangement of the dryer 11 and 12 left and right of the printing tower 7 and by the arrangement of otherwise identical dryer 11 and 12 on different sides of the web.
  • the dryers 11 and 12 are arranged directly next to the printing tower and preferably supported on the printing tower frame.
  • the printing tower 7 also forms in this sense a printing tower with integrated dryers.
  • the dryers 11 and 12 are aligned exactly vertically. Since the dryers 11 and 12 are moved in the horizontal direction from the overlap with the printing units 5 and 6, the printing tower 7 is lower than the printing tower 3, but on the other hand, wider and requires a longer path.
  • the web guide is the printing tower 3 of the embodiment of FIG. 1 optimal.
  • FIG. 3 shows a printing tower 10 in the so-called four-tower construction, in which the web B 1 in vertical web guide, before drying the left and right side of the web, two rubber rubber printing units 9 for each 2/2 pressure passes.
  • the web is deflected between the two printing units via at least one guide roller. Since this would lead to the touch of the freshly printed web page, the required web stabilization is achieved by a slight horizontal offset of the upper to the lower printing unit 9 in a modification.
  • FIG. 4 shows a correspondingly modified printing tower 17, in which the two rubber-rubber printing units 9, or more generally blanket-blanket units 9, to each other have a horizontal offset, which is preferably at least half a cylinder diameter and preferably at most twice the cylinder diameter of one of the blanket cylinder, if one measures the offset as a horizontal distance between the two next adjacent pressure columns of the printing units 9.
  • a horizontal offset which is preferably at least half a cylinder diameter and preferably at most twice the cylinder diameter of one of the blanket cylinder, if one measures the offset as a horizontal distance between the two next adjacent pressure columns of the printing units 9.
  • the two dryers 13 and 14 are combined into a sandwich arrangement and arranged opposite one another acting on each one of the two web sides.
  • the web B 1 or the sub-webs previously formed therefrom is or are conveyed without contact from the last printing nip of the printing tower 17 to a downstream guiding element, for example a guide roll, to the drying system 13, 14.
  • a downstream guiding element for example a guide roll
  • One of the two blanket cylinders, which form the last printing nip of the upper printing unit 9, and the relevant guide element form the guide for the web B 1 or the partial webs on the path section containing the dryer system 13, 14.
  • the drying system 13, 14 downstream guide element is arranged with a corresponding horizontal offset to the last printing nip.
  • the web B 1 or the partial webs already formed therefrom is or will therefore be conveyed with an inclination to the vertical by the dryer system 13, 14 consisting of the dryers 13 and 14.
  • the printing tower 17 allows a particularly simple, short path and the compact sandwich arrangement for the two dryers 13 and 14th
  • FIG. 5 shows a schematic representation of a copy of a newspaper copy, as it can be generated, for example, with a printing press according to the invention.
  • the booklet comprises a plurality of longitudinally folded sheets 20, 21, 22 and 23. At least one of the sheets was printed in one of the dryer-integrated printing towers and dried. At least one other of the sheets was printed in the at least one other printing tower and dried by beating. If only one of the sheets 20 to 23 in the printing tower with integrated dryer was printed and dried, it is preferably either the innermost sheet 2.3 or the outermost sheet 20.
  • the at least one actively dried sheet for example the sheet 23, is a high-gloss sheet and can in particular be printed in panorama format, ie provided with a printed image over the entire sheet width
  • the one or more in the cold-set method, ie dried by beating sheets or sheets is or are preferably (a) double page (s), ie he or she wear on both sides of the fold ever a printed image, as usual in newspaper printing.
  • a booklet produced entirely in higher quality or several such booklets may be part of a newspaper copy produced according to the invention.
  • the printing press according to the invention can also drive a newspaper production completely in the cold-set process and a magazine production completely with active drying, either in parallel or in succession. For parallel production, only the stations downstream of the printing, such as the turning device and the folding device, must be present accordingly.
  • the color layers to be "dried" are not polymerized by UV radiation but by polymerisation with electron radiation.
  • electrons are emitted from a tungsten filament in a vacuum and subtracted over a field of stress and nachbelectt.
  • the vacuum from the drying chamber at the electron exit window is separated by a thin titanium foil.
  • ESH dryers can also be built very compactly.
  • a particular disadvantage of ESH systems is the relatively high capital investment costs compared to UV systems, which means that the task of synthesizing relatively low color and investment costs is pending.
  • FIG. 9 For application of the ESH system variant for parallel drying of the front and back sides of a web according to FIG. 6 , show the FIG. 9 at the printing tower (17) a preferred web guide, which in principle the same way on the printing tower (10) of FIG. 3 is applicable.
  • the reference numeral (31) in FIG. 9 equals to FIG. 6 ,
  • FIG. 10 For application of the ESH system variant for parallel drying of the front and back sides of two webs according to FIG. 7 , show the Figure (10 ) a preferred web guide with two adjacent printing towers (17) or (10).
  • the reference numeral (32) in FIG. 10 equals to FIG. 7 ,
  • FIG. 8 For application of the ESH system variant for serial drying of the front and back sides of a web according to FIG. 8 , show the Figures 11 and 12 preferred web guiding variants on the printing tower (3), or with two juxtaposed satellite printing units (5) and (6).
  • the reference numeral (33) in Figures 11 and 12 equals to FIG. 8 ,
