Definitions

  • the invention relates to a filler piece for use in the pit of a printing unit cylinder in a web-fed rotary printing press, in particular an offset web-fed rotary printing press, in such a way that when adjacent pit openings overflow, the filler piece rolls on a similar filler piece arranged in the pit of a second cylinder.
  • a major advantage of the invention according to claim 1 is that by the design of the filler pieces according to the invention when rolling over adjacent pits, the filler pieces are in contact over their entire length and that the considerable contact forces are accordingly distributed so that the pressure per unit area is lower than at the known relatively short filler is.
  • a major advantage of the invention according to claim 2 is that quasi self-adjustment of the filler pieces is achieved, because due to the wear and thus height-related shortening of the filler pieces in the course of use, they no longer bend as much when they are rolled over, and thus virtually an “erection "of the filler pieces is to be expected, whereby the contact surfaces in the pit overflow become larger as a result of wear and tear and thus the contact pressure per unit area decreases, which in turn prevents further wear or reduces this.
  • Fig. 1 shows schematically two printing unit cylinders 1, 2, which are conventionally mounted in side walls (not shown), for example blanket cylinders of an offset web-fed rotary printing press with typically narrow cylinder channels 3, 4. If the printing unit cylinders 1, 2 are in operation with high force, for example of the order of magnitude one or two tons placed against each other, a bending line 5 or 6 results for each of the printing unit cylinders 1, 2 as a result of a rubber blanket adjustment via bearer ring.
  • the filler 7 has an inner, i.e. edge 9 near the pit floor, which is curved together with the pit floor 23 in accordance with the expected bending line 5 for the cylinder 1.
  • the outer, i.e. the edge 11 of the filler piece 7 remote from the pit floor, on the other hand, is planar or planar as seen in the axial direction of the cylinder 5.
  • the filler 8 is formed in the pit 4 and the pit bottom 24 of the printing cylinder 2, namely curved according to the expected bending line 6 on the inner edge 10 and flat on the outer edge 12, so that the edges 11, 12 preferably run in parallel.
  • the filler pieces 7, 8 are considerably more effective with regard to the damping or suppression of channel impacts, their service life being improved compared to shorter filler pieces, or cheaper or not so high-quality ones Materials are used.
  • the mutually curved edges 16, 18 of the filling pieces 13, 14 according to FIG. 2 have at their ends in practice approximately a maximum distance of 0.1 to 0.2 mm, i.e. 2 with regard to the curvature of the edges 16, 18 is extremely enhanced for the sake of clarity.
  • two or more segment-like cutouts 22 can also be used, which are shaped in such a way that they perform virtually the same function as a continuous filler piece 8.
  • this is useful e.g. fewer manufacturing problems, instead of several individual segments designed according to 22 with the same effect, preferably a continuous filler 8.
  • the filler pieces 13, 14 it is expedient, for example, to provide two brackets on the cylinders, so that the filler pieces in the center of the cylinder can possibly lift off somewhat from the pit floor in the relaxed state of the cylinder.
  • the filler pieces are fixed over the entire length of the cylinder, they are also bent in accordance with the bending of the printing unit cylinders, which is less problematic in the case of long printing unit cylinders, ie in the case of wide presses.
