Definitions

  • the present invention relates to a plate cylinder according to the preamble of claim 1.
  • Printing plate cylinders are known from the prior art, which receive printing plates at their periphery.
  • the printing plates can be received directly on the circumference of the cylinder or at the periphery of a hollow cylindrical shell element, wherein the shell element is in turn received on a reduced diameter portion of the cylinder.
  • the Japanese Patent Application No. 2000-954 A describes such a printing plate cylinder having a cylinder body and an applied to a portion of the cylinder body with a smaller diameter shell member which is independently movable for adjusting the side and circumferential register of a pressure plate mounted on the shell member relative to a mounted on the other side of the printing plate cylinder on the cylinder body pressure plate ,
  • the jacket element has a uniform wall thickness.

  • a plate cylinder according to the invention with a cylinder body and at least one jacket element, which is displaceable on the cylinder body at least in the axial direction and has a channel for holding a pressure plate, is characterized in that the jacket element has an inwardly directed projection at least in the area of the channel, wherein the channel extends into the projection.
  • An advantage of the invention can be found in the fact that the arrangement of the channel in the projection of the jacket element, the wall thickness of the jacket member can be reduced, so that the diameter of the cylinder body simultaneously sections, especially in reinforcing ribs designed as projections, can be increased. This advantageously improves the flexural rigidity of the cylinder body.
  • the present invention provides sufficient space for the channel and clamping mechanism in the inwardly projecting projection, while at other locations advantageously low material thickness is possible. Since this also reduces the weight of the jacket element, the displacement of the jacket element during registering operations is advantageously facilitated.
  • the jacket element is preferably movable relative to the cylinder body at least partially in the circumferential direction, in particular to Registerstellvor réellen.
  • the jacket member may also have a plurality of inwardly directed projections.
  • the jacket member may have an additional channel circumferentially spaced from the channel which extends into another inward projection.
  • the projections are preferably arranged symmetrically in the circumferential direction (preferably at angles of 360 ° / n where n is an integer greater than 2) and in particular have substantially equal distances from one another.
  • the cylinder body preferably comprises at least one outwardly directed projection, which comes to lie in the circumferential direction at least partially adjacent to a projection of the jacket element.
  • projections of the cylinder body advantageously form between them a gap for a projection of the jacket element, wherein the intermediate space wider than the projection of the jacket element.
  • the cylinder body preferably carries a plurality of jacket elements in the axial direction, in particular a jacket element at one or both end sections.
  • the page register can be adjusted, in particular to compensate for the fan-out effect (width of the web when absorbing moisture).
  • a clamping device can be arranged in the channel.
  • the jacket member may have a wall thickness between the inwardly projecting projections, which is smaller than the corresponding dimension of a clamping device.
  • a plurality of pressure plates can be accommodated on the jacket element.
  • two pressure plates can be accommodated on a jacket element, wherein in turn at each end of the cylinder body a jacket element can be accommodated.
  • two pressure plates can be accommodated on the cylinder body, so that the cylinder carries a total of 6 pressure plates in the axial direction. It can be added in the circumferential direction 1 or 2 printing plates.
  • the jacket element can be designed as a sleeve.
  • Fig. 1 shows a printing cylinder, more precisely a plate cylinder or plate cylinder 10, z. B. for printing in a direct or indirect process on a substrate such as paper, which has a cylinder body 14 with two ends 12 and 22. The ends can be designed as a cylindrical pin.
  • a substantially hollow-cylindrical shell element 16 is arranged around the cylinder body 14.
  • the jacket element 16 is preferably sleeve-shaped.
  • the cylinder body 14 comprises, on a second portion facing the end 12, which does not receive a jacket element, as does the jacket element 16, on its outer surface an image area 24.
  • a print image to be printed is defined in the respective image area.
  • the two image areas 24 have a substantially equal circumference, d. H. the outer diameter of the cylinder body 14 in the region of the second portion and the outer diameter of the jacket element 16 in the region of the first portion are substantially equal.

  • Fig. 2 shows a cross section of the plate cylinder 10 shown in Fig. 1 along the line II-II.
  • the jacket member 16 is circumferentially disposed about the cylinder body 14, d. H. it comprises the cylinder body 14.
  • the jacket element 16 has an inner surface 56 arranged around the cylinder body 14.
  • the cylinder body 14 has outwardly directed projections or lugs 62 which form a clearance S between each other in the circumferential direction.
  • the inner surface 56 of the sheath member 16 has inwardly directed projections or lugs 52 which fit into the interstices S with sufficient clearance and thus free spaces 58, d. H. Define free spaces.
  • the gap S is wider in the circumferential direction than the projection 52, so that between a side 66 of the projection 62 and a side 72 of the projection 52 with a central arrangement of the projection 62 in the space S, a distance D, through which movement of the jacket member 16 in Circumferential direction for adjusting the circumferential register of the jacket member 16 is made possible.
  • the inner surface 56 of the shell member 16 and the cylinder body 14 contact each other in a contact region 53 which is fitted with a friction reducing material, e.g. PTFE, may be provided to facilitate the relative movement in the axial direction and in the circumferential direction.
  • a friction reducing material e.g. PTFE
  • the projections on the jacket element and on the cylinder body form axially extending ribs or webs, which advantageously lead to a reinforcement or stiffening of the respective component.
  • an axially extending channel 30 for receiving the plate edges of an image-bearing printing plate 40, such as a flexible offset printing plate.
  • an image-bearing printing plate 40 such as a flexible offset printing plate.

  • the jacket element 16 thus comprises regions 54 of reduced material thickness or thickness between the projections 52 (regions of high material thickness or thickness).
  • the projections 62 of the cylinder body come to lie between the projections 52 of the jacket element 14, ie radially relative to the regions 54.
  • the jacket element 16 and the cylinder body 14 thus form a serration. Since the cylinder body 14 has a larger diameter in the areas of the projections 62 than in the areas of the spaces S, such a cylinder body advantageously has a greater flexural rigidity than a cylinder body without projections 62. Improved flexural rigidity can reduce problems such as streaking in printing or prevent.
