Definitions

  • the invention relates to a device for changing the web position of a Printing material web according to the preamble of claim 1.
  • the invention has for its object a device for changing the Web position of a printing material web according to the preamble of claim 1 create that is inexpensive and with simple, space-saving technical means is feasible.
  • Fig. 1 shows one with two superimposed double printing units 1; 2 in horizontal cylinder arrangement equipped H-pressure unit 3.
  • Each Double printing unit 1; 2 consists of two printing units 4; 5 or 6; 7 with each an outside forme cylinder 8 to 11 and an inside Transfer cylinders 12 to 15. Between the transfer cylinders 12; 13 or 14; 15 of a double printing unit 1; 2 becomes one in indirect printing Printing material web 16; 17 in a pressure point at the same time on both sides with one Color occupied.
  • the double printing unit upstream functional groups the printing substrate web 16 in a before lower printing unit 4 freely sagging web loop shown in dashed lines 22, which only continues the double-sided color assignment of the Printing substrate web 17 in the lower double printing unit 1 Support element 23 rests. If the web loop 22 is fully formed, one of the printing material web 16 laterally articulated on the frame appearance 24 Dash-dotted representation transverse to the substrate web 16 in the web loop 22 pivoted so that the operation of the upper printing unit 6 can be done.
  • the appearance 24 - pivoted back for example, by a pressure-operated working cylinder and subsequently the web loop 22 by means of driving the Double printing unit 2 and this subordinate web-promoting Functional groups possibly in cooperation with the unwinder regressed.
  • a shown in dashed lines in Fig. 1 in front of the lower right printing unit 5, also lying on a support element 25, by means of a pivotable Appearance 26 for operating the upper right printing unit 7 accessible Web loop 27 is different from the web loop 22 by a web-promoting drive of the printing double printing unit 1 and this upstream functional groups - such as the unwinder and Infeed unit 18 - when the double printing unit 1 is at a standstill Functional groups generated, which in turn when the double printing unit 1 the web loop 27 can be driven to retract.
  • FIG. 2 shows one of two H printing units 28 arranged one above the other; 29 existing six-tower 30, in which for an occupancy of a printing substrate 31 on one side with two and the other side with four colors Printing material web in the lower left printing unit 32 directly from the forme cylinder is covered with color. Due to the overlying printing unit 33 concealing web guide is used for the operation of this printing unit 33 Printing material web 31 analogous to FIG. 1 in a web loop 34 downwards lowered, over which a step 35 is pivotally arranged.
  • Fig. 3 shows three a horizontally running printing material web 36 on both sides Double-color printing units 37, each covering three colors, arranged one behind the other; 38; 39 each with a vertical cylinder arrangement.
  • Regarding the drive of the Cylinder applies to what has already been said in relation to FIG. 1.
  • the upper printing unit 40 41 the one that hides it
  • trainees Web loop 44; 45 are lowered into which an appearance 46; 47 swiveling on Rack is installed.
