Definitions

  • the invention relates to a gravure cylinder, consisting of a core of a practically non-deformable material and a sleeve releasably connected to it, which can be pushed onto and removed from the core by means of a compressed air cushion, the core having at least one channel for guiding compressed air to its jacket surface has, the sleeve is composed of at least four concentric layers of different materials, of which the inner layer consists of a relatively thin, inherently stable, low-elastic material, the second, outward layer consists of a more elastic and slightly compressible material, the third Layer consists of a rigid and inherently stable material and the fourth, outer layer consists of a copper layer having the engraving, and wherein the cylinder with the same inner diameter of the sleeve by different thicknesses of the second and / or the third layer of the sleeve different Can have outer diameter.
  • This rotogravure cylinder has proven itself in terms of its manageability and the print quality that can be achieved, but it has proven itself emphasized that it still needs to be improved with regard to its operational properties, in particular for continuous use under high loads and for permissive use and processing in alternation with conventional gravure cylinders.
  • the new gravure cylinder is said to have improved resilience and durability.
  • the new rotogravure cylinder should be able to be used and machined without problems in alternation with conventional rotogravure cylinders.
  • the ribs on the outside of the first layer of the sleeve ensure that relative displacements or twists between the individual layers of the sleeve or within a position of the sleeve can practically no longer occur, since the ribs oppose such a displacement with a very high mechanical resistance.
  • the ribs are made of the same material and in one piece with the first layer of the sleeve.
  • the ribs For the shaping of the ribs, it is preferably provided that they each have two curved flanks which enclose an acute angle radially on the outside and which extend radially on the inside into the outer surface of the first layer. This results on the one hand in a high stability and shear strength of the ribs and on the other hand a secure frictional connection to the next position of the sleeve.
  • a further improvement of the force flow between the first and the second position of the sleeve can be achieved in that the ribs are arranged inclined or tilted in the direction of rotation of the cylinder.
  • the ribs are arranged in several groups of two, each with a pair of closely adjacent ribs.
  • This arrangement of the ribs has a particularly high mechanical stability and can advantageously be produced in a simple manner by pressing a round material rod into the not yet hardened material of the first layer, preferably glass fiber reinforced plastic, for each pair of ribs provided and removing it again after the plastic has hardened .
  • the number of ribs or pairs of ribs is preferably four to ten, these being evenly distributed over the circumference.
  • a further step in the direction of improved durability of the gravure cylinder is done in that the second layer of the sleeve is wound from a continuous strand of material made of rubber or polyurethane in the form of a spiral with slightly spaced spiral paths under elastic tension on the outside of the first layer of the sleeve .
  • the ribs press firmly into the inside of the strand of material, as a result of which a high degree of security against rotation is achieved.
  • the height of the ribs and the thickness of the strand of material are preferably selected so that the ribs are pressed into the outer surface of the strand of material forming the second layer of the sleeve. The ribs thus also contribute to securing against rotation between the second and third layers of the sleeve.
  • a pretension which has stretched the material strand of the second layer of the sleeve relative to the relaxed state to approximately twice its length has proven to be particularly favorable for the gravure cylinder.
  • a preload of this magnitude ensures, on the one hand, that the second layer of the sleeve is firmly seated on the first layer and, at the same time, ensures that the second layer of the sleeve, which is used for pulling and pulling the sleeve onto the core or from, is still sufficiently elastic and compressible Core is required.
  • a cover covering at least the circumferential gap between the spiral passages of the material strand preferably an adhesive strip
  • the adhesive strip can be provided with an adhesive layer both on the inside and on both sides. Its surface can also be provided with a friction-increasing structuring.
  • the intaglio cylinder preferably has an end-face metal ring at the ends of the sleeve, the inside diameter of which is slightly larger than the inside diameter of the first, inner layer of the sleeve, and the outside diameter of which is equal to the outside diameter the third layer of the sleeve and on which the ends of the copper layer are applied.
  • the two metal rings are preferably made of brass, copper, lead or lead alloy and are L-shaped in cross-section, the outside of one L-leg abutting the inside of the copper layer and the outside of the other L-leg forming part of the sleeve face. This provides a large current transmission area and a large line cross section.
  • the intaglio cylinder preferably has a sheet metal cylinder, preferably made of copper, the longitudinal diameter of which is embedded on the inside of the first layer in the front end areas, preferably the inside diameter of which is that of the inside Position corresponds and which is electrically connected to the adjacent metal ring.
  • a sheet metal cylinder preferably made of copper, the longitudinal diameter of which is embedded on the inside of the first layer in the front end areas, preferably the inside diameter of which is that of the inside Position corresponds and which is electrically connected to the adjacent metal ring.
  • the intaglio cylinder can have a circumferential locking mechanism formed from at least one groove and a spring and present on at least one end region of the core and sleeve .
  • a preferred embodiment of the lock is that it consists of two toothed rings on each end of the cylinder, one ring being connected to the core and having external teeth, one ring being connected to the sleeve and one internal toothing fitting into the external teeth the inner diameter of the toothed ring of the sleeve leading in advance when the sleeve is pulled onto the core is slightly larger than its inner diameter and the outer diameter of the toothed ring arranged at the opposite end of the core is slightly smaller than the outer diameter of the core.
  • the size ratios of the rings mentioned ensure that they do not in any way hinder the pulling and pulling of the sleeve onto the core or from the core.
  • the toothed rings present on the sleeve can be made in one piece with the metal rings on the end faces of the sleeve in order to simplify the manufacture of the cylinder.
  • the rotogravure cylinder according to the present invention can have both a cylindrical core and a conical core, as is known per se, the latter embodiment being preferred because of the easier pulling on and pulling off of the sleeve.
  • a cylindrical core and a conical core, as is known per se, the latter embodiment being preferred because of the easier pulling on and pulling off of the sleeve.
  • only the diameter of the metal rings and toothed rings need to be adjusted.
  • the transition from the taper of the inside of the sleeve to the completely cylindrical outer surface of the sleeve preferably takes place within the third layer of the sleeve, the thickness of which can be varied within wide limits.
  • the illustrated embodiment of the gravure cylinder 1 consists of a core 2 with a conical outer surface and a sleeve 3 mounted thereon with a suitably shaped, also conical inner surface and a cylindrical outer surface 30.
  • the conicity of the core 2 exaggerated for reasons of clearer visibility; in practice it is only about 0.1 - 0.2 mm per meter of core length.
  • an axle stub 24 or 25 is arranged for mounting the printing cylinder 1.
  • the length of the air channel 21 is approximately one third to half of the length of the core 2.
  • a radially extending air channel 22 extends from the end of the longitudinal channel 21 and ends freely on the outer surface 20 of the core 2.
  • the channels 21 and 22 serve to guide compressed air from the connection 23 between the outer surface 20 of the core 2 and the inside of a drawn sleeve 3. In this way, as is known per se, a compressed air cushion is formed between the core 2 and the sleeve 3, which causes a slight expansion of the sleeve 3, which allows the sleeve 3 to be pushed on and pulled off.
  • the viewer's gaze falls on the outer surface 20 of the core 2.
  • the first layer 4 of the sleeve 3 can be seen. This consists of glass fiber reinforced plastic and has a thickness of about 1 mm, for example.
  • a plurality of ribs 41 which extend in the longitudinal direction of the gravure cylinder 1 and are arranged in pairs, are arranged, which are made in one piece with the material of the layer 4.
  • the second layer 5 of the sleeve 3 is visible.
  • This consists of a continuous, in the form of a coil wound on the second layer 4 of the sleeve 3 strand of material 51, preferably rubber or polyurethane.
  • a circumferential gap 52 remains between the individual spiral turns of the material strand 51, which enables a certain compression of the material strand 51 in the radial direction.
  • the strand of material 51 is wound onto the layer 4 under such a pretension that the ribs 41 present on it are pressed through to the outside of the strand of material 51 of the second layer 5 of the sleeve 3.
  • third layer 6 of sleeve 3 which here consists of a glass fiber reinforced plastic and has a relatively large thickness.
  • sleeve 3 which here consists of a glass fiber reinforced plastic and has a relatively large thickness.
  • it ensures a transition from the taper of the two first layers 4 and 5 of the sleeve 3 to a cylindrical outer shape.
  • the strong conicity shown in Figure 1 is greatly exaggerated for reasons of illustration; in practice, a taper of about 0.1 - 0.2 mm per meter core length is sufficient.
  • the outer layer 7 of the sleeve 3 can be seen, which consists of a copper layer.
  • the application of the copper layer 7 to the preceding layer 6 of the sleeve 3 is preferably carried out in such a way that a copper base layer is first applied using the flame spraying method and that then another copper plating takes place galvanically.
  • a toothed ring 26 can finally be seen in FIG. 1, which forms part of a lock between the sleeve 3 and the core 2. The operation of this lock will be explained in more detail later.
  • Figure 2 shows the right end portion of the gravure cylinder 1 of Figure 1 in longitudinal section.
  • the inner part of the cylinder 1 is again formed by the core 2 with its front axle stub 25.
  • the conical outer surface 20 of the conical surface 20 also lies on the inside of the first layer 4 of the sleeve 3.
  • This is followed by the second layer 5 of the sleeve 3, which consists of the continuous strand of an elastic material.
  • the circumferential gap 52 can be seen between the individual coils of the material strand of the layer 5, which allows the material strand to expand laterally when the layer 5 is compressed in the radial direction. This will slightly widen the inside of the sleeve, i.e. H.
  • the inner layer 4 with elastic deformation of the layer 5 allows without affecting the outer layers 6 and 7 of the sleeve 3.
  • the third layer 6 of the sleeves 3 has a relatively large thickness and forms the transition between the conicity of the sleeve interior and the cylindrical shape of the sleeve exterior.
  • the copper layer 7, which forms the outer layer of the sleeve 3, has a constant thickness throughout. At the front end of the cylinder 1, the copper layer 7 is rounded, which results in a cylinder jacket surface 30 which corresponds to that of conventional gravure cylinders.
  • the sleeve 3 On its end face, the sleeve 3 has two additional components.
  • the first of these two parts is a metal ring 8 ⁇ , which is L-shaped in cross section.
  • the Outside 80 ⁇ of one L-leg extends in the longitudinal direction of the cylinder 1 and lies flat against the inside of the copper layer 7.

  • the sheet metal ring 9 ⁇ is slotted in at least one, preferably several places in the longitudinal direction of the cylinder in order to allow the sheet metal ring to move along when the inner layer 4 of the sleeve 3 is widened.
  • the metal ring 8 ⁇ is in a part of the inner end of the front L-leg in an electrically conductive connection with the outside of the sheet metal ring 9 ⁇ .

  • a toothed ring 27 can be seen at the right end of the core 2 in FIG. 2, which has external teeth and is inserted into the end face of the core 2.
  • the metal ring 8ring already mentioned has on its end region of the inner L-leg not abutting the sheet metal ring 9 ⁇ an internal toothing 82 ⁇ which is designed to match the external toothing of the toothed ring 27. This makes it possible that when the sleeve 3 is pushed onto the core 2, the toothed ring 27 and the toothing 82 Metall of the metal ring 8 ⁇ can interlock. This results in an effective locking between core 2 in the circumferential direction of gravure cylinder 1 and sleeve 3 causes.

  • the metal ring 8 has an internal toothing 82 which is designed to match the toothing of the toothed ring 26 and engages precisely in it.
  • FIGS. 1, 2 and 3 show that the two toothed rings 26 and 27 of the core 2 of the gravure cylinder 1 have different diameters.
  • the difference in diameter is not only determined by the conicity of the core, but goes beyond it.
