Definitions

  • the invention relates to a device on cylinders or blanket-bearing cylinders of a rotary printing press, in particular sheet-fed offset press, for holding the ends of intermediate layers made of paper or cardboard in a tensioning channel comprising clamping means running parallel to the cylinder axis in the cylinder jacket.
  • intermediate layers made of paper or cardboard are used as part of the elevator of the cylinder carrying a blanket or a plate to adjust the diameter and the preload of the elevator.
  • the intermediate layer is inserted into the cylinder pit in the space between the pit wall and a tension rod and pressed against the pit wall by turning the eccentric tension rod.
  • the object of the invention is to provide a device of the type mentioned, which ensures simple operation with little design effort.
  • This object is achieved in that an angled part of the intermediate layer of magnetic film strips is held in contact with a metallic part of the tensioning channel.
  • an axially parallel tensioning channel 5 is incorporated into the cylinder jacket 1 of a rubber blanket cylinder 2, the elevator of which consists of the rubber blanket 3 and an intermediate layer 4, for receiving the holding devices for the elevator.
  • the front angled part 6 of the intermediate layer 4 is clamped between the magnetized side of a first magnetic film strip 7 and a magnetized side of a second, double-acting magnetic film strip 8.
  • the other magnetized side of the second magnetic film strip 8 holds the entire package of two magnetic film strips 7 and 8 and the intermediate layer 4 in contact with a side wall 9 of the tensioning channel 5.
  • the side wall 9 has a rectangular projection 10 in its upper part, which extends from the Leading edge 11 of the tensioning channel 5 extends over part of its depth 12 and forms with its lower edge 13 a stop for the upper edge of the second magnetic film strip 8.
  • the width 14 of the projection 10 is selected so that it corresponds to the thickness of the second magnetic film strip 8.
  • an axially parallel tensioning channel 17 is incorporated into the cylinder jacket 15 of a rubber blanket cylinder 16, which holds the holding devices of an elevator consisting of a rubber blanket 18 and an intermediate layer 19 records.
  • the side wall 20 of the tensioning channel 17 encloses a smaller angle than 90 ° with the tangent at its leading edge 21.
  • the front angled part 22 of the intermediate layer 19 is clamped between the magnetized side of a first magnetic foil strip 23 and a magnetized side of a second, double-acting magnetic foil strip 24. The entire package is held by the other magnetized side of the second magnetic film strip 24 on the side wall 20 of the tensioning channel 17.
  • the axially parallel alignment of the front edge of the intermediate layer 22 is achieved here by pushing the upper edge of the second magnetic film strip 24 flush against the leading edge 21 of the tensioning channel 17.
  • the depth 25 of the tensioning channel 17 is greater than the width of the magnetic foil strips 23 and 24.
  • an axially parallel tensioning channel 28 is incorporated into the cylinder jacket 26 of a rubber blanket cylinder 27, which serves to accommodate the holding devices for the elevator, consisting of rubber blanket 29 and intermediate layer 30.
  • the front part 32 of the intermediate layer 30, which is angled over the leading edge 31 of the tensioning channel 28, is held against a side wall 34 of the tensioning channel 28 by a simple magnetic foil strip 33.
  • the depth 35 of the tensioning channel 28 is selected so that it equals or slightly exceeds the width of the magnetic foil strip 33.
  • the front edge of the intermediate layer 30 and the lower edge of the magnetic foil strip 33 thus find a common stop on the bottom 36 of the tensioning channel 28.
  • All three exemplary embodiments have in common that only the front part 6, 22 or 32 of the intermediate layer 4, 19 or 30 is held in the tensioning channel 5, 17 or 28.
  • the other end, not shown, is freely movable and is pulled along when the rubber blanket 3, 18 or 29 is stretched and over the entry edge 11, 21 or 31 not shown opposite edge of the clamping channel 5, 17 or 28 clamped.
  • the double-acting magnetic film strips 8 and 24 are preferably produced by gluing two simple magnetic film strips on the back. It is advantageous if the U-magnets integrated in the magnetic foils run in the axial direction, that is to say parallel to the start edge of the print. This determination of the magnetic direction ensures an automatic parallel alignment of the film strips to one another when the intermediate layer is clamped when the first magnetic film is placed on the second.
  • the selected exemplary embodiments do not reflect the core idea of the invention in all possible forms. Other embodiments can also be derived by a different combination of the features shown. It is also conceivable that the magnetic film strips not only on the side wall of the tensioning channel, but also on other metallic parts arranged in it, such as. B. to attach to a clamping spindle or rail. Holding devices for rubber blankets are known to the person skilled in the art and have therefore not been shown.
