Definitions

  • the present invention relates to a guide device for a sleeve. or printing cylinder, especially for flexographic printing as well than sleeves or cylinders fitted with this device.
  • the surface of the sleeves is corrected to give it a state of suitable finishing and especially so that the development, linked to the accuracy of the diameter, corresponds well to the development sought.
  • the photograph is attached to the sleeve using a double-sided adhesive.
  • Markers are integrated into the picture and come from manufacturing with it, benchmarks that should be made to coincide with those of the muff.
  • the present invention proposes to overcome these drawbacks by means an integrated device for guiding plate laying and cutting which is very practical for the user, which allows adjustments and cuts so much according to generators than according to circumferences, which is priced at is fully compatible with the price of supports, sleeves or cylinders, the amortization of which is almost immediate, which is neutral with respect to mechanical strength of the sleeve or cylinder, which is also self-compensated from a balancing point of view and applicable to all fiber-free products on the surface.
  • the integrated guide device for the laying and cutting using a cutting tool, a plate and / or double-sided adhesive interposed on a sleeve or on a printing cylinder, in particular in flexography, said sleeve or cylinder comprising an external coating capable of being machined in depth is characterized in that it comprises at least one guide longitudinal, along a generator, and / or a peripheral guide, along a circumference, formed within a matrix of very hard material, reported in the thickness of said outer coating.
  • the matrix of material high hardness is housed in a groove machined in the thickness of the coating outside.
  • the throat includes immobilization means in the thickness of the coating, for example a dovetail profile.
  • the guide has a section adapted to the profile of that of the cutting tool.
  • the matrix is made of material polymer loaded with metal and / or ceramic particles.
  • the invention also relates to the sleeve or cylinder equipped with this device.
  • the sleeve 10 comprises a single groove 12 longitudinal, two external peripheral grooves 14 and one groove 15 middle peripheral so as to limit the unnecessary space requirement of the drawing.
  • a plate 16 is attached to said sleeve, from the groove 15, middle peripheral.
  • the sleeve simply comprises an inner layer 18, in fibers embedded in resin, a thickness compensation layer 20 made of cellular material, a belt 22 of great rigidity and a covering 24 exterior resin finish allowing surfacing by grinding.
  • the device according to the invention is not limited to this type of embodiment of sleeve but more generally applicable to all sleeves or cylinders whose outer covering is free of fibers and capable of being machined.
  • the sleeve 10 is blank, out of manufacturing, prerectified.
  • a groove 26 with a tail profile is machined dovetail, in the preferred embodiment.
  • This groove 26 is of a depth less than the thickness of the siding.
  • the sleeve includes for example 4 grooves, equally spaced at 90 °, for obvious reasons of symmetry.
  • This groove 26 is then lined with a matrix 28 of material of the type polymer loaded, for example with metal and / or ceramic particles so as to give it a high hardness and to resist friction. This step corresponds to that of FIG. 3C.
  • the present invention proposes to add to the charged polymer, a lubricant such as graphite and / or molybdenum, these two examples cannot be considered as limiting.
  • This matrix is for example rectified, simultaneously with the rectification end of the sleeve, after polymerization, to avoid any protruding particles.
  • Each die is then machined in its middle part to form an integrated guide 30, the cross section of which corresponds to that of a blade cutter and whose depth is less than the thickness of the die 28 reported.
  • This machining is carried out using a diamond tool taking into account the hardness of the charged polymer matrix.
  • the dovetail profile provides better integration of the added matrix but is not a necessity because the polymer matrix has excellent adhesion with the other resins constituting the coatings, it suffices to choose the resins compatible with those coating, which is within the reach of ordinary skill in the art.
  • a cylinder made of metal for example of alloy aluminum
  • the alloy has a hardness which is often insufficient to allow guidance of a cutting tool and in addition the aluminum alloys easily mark under the blade effects.
  • the advantage of using a polymer material is the implementation easy in the groove and the final surface finish which can be corrected while offering significant hardness possibilities.
  • External peripheral grooves are commonly used for cutting of the double-sided adhesive which protrudes when the plate is positioned at starting from the middle groove, which is the most common case.
