Definitions

  • the invention relates to a sleeve, in particular a blanket sleeve, according to the preamble of patent claim 1.
  • Sleeves favor a quiet and shock-free unwinding of printing press cylinders due to the lack of interruption of otherwise commonly existing clamping channels on the circumference of the cylinder.
  • DE 199 50 643 A1 discloses a sleeve for an offset roller printing press, which has a total of four-layered construction.
  • the sleeve according to DE 199 50 643 A1 has an inner layer designed as a carrier layer and an outer layer designed as a cover layer for pressure transmission, wherein two further layers are present between the carrier layer and the cover layer.
  • the sleeve according to DE 199 50 643 A1 has a hollow cylindrical shape with a cylindrical inner surface and a cylindrical outer surface, wherein all layers of the sleeve have cylindrical inner surfaces and cylindrical outer surfaces.
  • EP 0 819 550 B1 discloses a sleeve for a printing press having a cylindrical outer surface and a conical inner surface. Accordingly, the sleeve according to EP 0 819 550 B1 does not have a hollow cylindrical shape.
  • the present invention is based on the problem to provide a novel sleeve, in particular a novel rubber blanket sleeve.
  • the inner layer formed as a carrier layer is curved convexly or concavely on the radially outer side, wherein a layer adjoining the carrier layer has, on a radially inner side, a curvature which is complementary to the curvature of the radially outer side of the carrier layer.
  • a multilayer sleeve for a printing press, which has an overall hollow cylindrical shape with a cylindrical inner surface and a cylindrical outer surface.
  • the carrier layer is cylindrical on its radially inner side and curved on its radially outer side either convex or concave.
  • a layer adjoining the carrier layer has on a radially inner side a curvature which is complementary to the curvature of the radially outer side of the carrier layer.
  • the present invention proposes a completely novel construction for a hollow-cylindrical sleeve, wherein opposite sides of adjoining layers of the sleeve have complementary curvatures, so that ultimately the outer contour of the sleeve does not deviate from a hollow cylindrical shape.
  • completely novel sleeve properties can be realized.
  • line force distributions of the outer, printing and web-guiding outer layers can be influenced.
  • Fig. 1 shows a first embodiment of a sleeve 10 according to the invention in longitudinal section, wherein a longitudinal central axis 11 of the sleeve 10 is shown in phantom in Fig. 1, and wherein the longitudinal center axis 11 of the sleeve corresponds to a sleeve positioned on a printing machine sleeve of the axis of rotation of the sleeve 10.
  • the sleeve 10 of the embodiment of FIG. 1 has a two-layered construction of an inner layer formed as a carrier layer 12 and an outer layer formed as a cover layer 13, wherein the cover layer 13 serves for pressure transmission.
  • the sleeve 10 has a hollow cylindrical shape with a cylindrical inner surface 14 and a cylindrical outer surface 15.
  • the outer surface 15 is used for pressure transmission.
  • a radially outer side 16 of the support layer 12 is convexly curved and a radially inner side 17 of the adjoining the support layer 12 cover layer 13 has a complementary curvature, that is concavely arched. Accordingly, the thickness of the carrier layer 12 and the cover layer 13 varies along the longitudinal central axis 11, but the thickness of the entire sleeve 10 remains unchanged.
  • FIG. 2 shows a second exemplary embodiment of a sleeve 18 according to the invention.
  • the sleeve 18 of FIG. 2 again has a longitudinal central axis 19 and a carrier layer 20 and a cover layer 21.
  • the sleeve 18 of FIG. 2 is accordingly like the sleeve 10 of FIG 1 has two layers and features a hollow cylindrical shape with a cylindrical inner surface 22 and a cylindrical outer surface 23.
  • a radially outer side 24 of the support layer 20 is concavely curved and a radially inner side 25 of the cover layer 21 convex.
  • the opposite sides 24 and 25 of the adjacent layers 20 and 21 have complementary curvatures.
  • FIGS. 1 and 2 two-layered sleeves 10 and 18 are shown.
  • 3 and 4 show sleeves according to the invention, which have a three-layer structure.
  • Fig. 3 shows a sleeve 26 having an inner layer 27, a cover layer 28 and a positioned between the inner layer 27 and the cover layer 28 intermediate layer 29.
  • the sleeve 26 in turn has a hollow cylindrical shape with a cylindrical inner surface 30 and a cylindrical outer surface 31, wherein the cylindrical outer surface 31 of the pressure transmission is used.
  • a radially outer side 32 of the carrier layer 27 is convexly curved and a thereto adjacent, radially inner side 33 of the intermediate layer 29 has a, complementary, namely concave curvature.
  • a radially outer side 34 of the intermediate layer 29 is curved convexly, and a thereto adjacent, radially inner side 35 of the outer cover layer 28 is concavely curved. Accordingly, the contiguous sides 34 and 35 of intermediate layer 29 and outer cover layer 28 also have complementary cambers.
  • the radially outer side 34 of the intermediate layer 29 as well as the radially inner side 35 of the cover layer 28 can also be contoured in a cylindrical manner. Furthermore, it is possible for the radially outer side 34 of the intermediate layer 29 to concave concave and the radially inner side 35 of the cover layer 28 to bulge convexly.
  • FIG. 4 shows a further exemplary embodiment of a sleeve 36 according to the invention.
  • the three-layer sleeve 36 of FIG. 4 in turn has an inner layer 37, a cover layer 38 and an intermediate layer 39 positioned between the inner layer 37 and the cover layer 38.
  • 4 again has an overall hollow cylindrical shape with a cylindrical inner surface 40 and a cylindrical outer surface 41.
  • a radially outer side 42 of the inner layer 34 is concavely curved and a radially inner side 43 of the intermediate layer 39 is convex, so that the opposite sides 42 and 43 of adjacent inner layer 37 and intermediate layer 39 have complementary arches.
  • a radially outer side 44 of the intermediate layer 39 is curved convexly and a radially inner side 35 of the cover layer 38 is concave, so that these adjoining sides 44 and 45 have complementary curvatures.
  • the number of layers of the sleeve and the specific curvatures of the adjacent, complementarily curved sides can be varied. All embodiments have in common that the radially outer sides 16, 24, 32 and 42 of the carrier layers 12, 20, 27 and 37 are curved either concave or convex, and that the adjacent side 17, 25, 33 and 43 of the adjacent Layer 13, 21, 29 and 39 is curved in a complementary manner.
  • the sleeves 10, 18, 26 and 36 have a hollow cylindrical shape with a cylindrical inner surface and cylindrical outer surface.
  • the carrier layers 12, 20, 27 and 37 of the sleeves according to the invention are preferably incompressible and metallic.
  • the covering layers 13, 21, 28 and 38 serving for pressure transmission are compressible and preferably designed as rubber layers.
