Definitions

  • the subject of the present invention is a printing sleeve. intended to be mounted on cylinders flexographic printing machines.
  • flexographic printing machines that include either cylinders on which are directly fixed the printing plates, for example with adhesives double-sided, i.e. support cylinders on which are arranged on the plate sleeves, arranged coaxially at the support cylinder and designed to receive pictures printing.
  • This sleeve-bearing cylinder is provided, at its periphery, with through holes, which creates an air mattress as soon as the sleeve begins to be sufficiently threaded, in front thus facilitate the mounting of this sleeve.
  • the present invention aims to overcome the drawbacks of the prior art as just summarized, in allowing sleeves to be mounted relatively easy, allowing installation even on cylinders full or not equipped with air passage holes, by providing different variants for applications with flexographic printing machines whose mechanical characteristics are variable, leading to the manufacture of products with a lower cost price to those of the prior art, and by providing for the use of current materials, especially composite materials, so to realize, in addition to the other advantages, savings of weight.
  • the flexographic printing sleeve intended to be mounted on a support cylinder comprises two flanges arranged at the ends a rigid annular cylinder with an outer wall and an interior wall, designed to be coaxial with support cylinder, including the outer face of the outer wall is designed to support a printing plate and the inner wall is composed of a deformable wall elastically and radially, over at least part of its length, the inner face of this inner wall being arranged opposite the external face of the support cylinder, inner wall which forms with the outer wall a hermetic chamber, connected by a valve to a source of fluid, so as to deform the elastically deformable wall and press it on the outside of the cylinder support.
  • the elastically deformable wall has a diameter nominal interior greater than the outside diameter of the support cylinder and the fluid introduced into the chamber, after mounting is at a pressure higher than that of the atmospheric pressure
  • the sleeve includes an inflatable envelope, disposed in the hermetic chamber, equipped with a fluid connection nozzle so as to allow it to swell.
  • An improvement of the invention provides for having a bar fitted with sizes, arranged between the envelope and the inner face of the outer wall of the sleeve.
  • the elastically deformable wall has an inside diameter nominal lower than the outside diameter of the cylinder support and the fluid introduced into the chamber, before mounting, is at a pressure lower than that of the pressure atmospheric.
  • the sleeve is made in composite material.
  • This composite material comprises at least one layer of cellular honeycomb material with at least one layer of resin on the inside and at least one layer of resin on the outer face.
  • the layer of nest material of bees is shaped by wrapping with a section annular.
  • one flanges and the inner and outer walls of the sleeve chamber simultaneously came from manufacturing.
  • the present invention also relates to methods of mounting such chamber sleeves.
  • the support cylinder is referenced 10 and 12 the printing sleeve.
  • the support cylinder comprises axes in a known manner 14 allowing it to be mounted in a printing machine flexographic.
  • It includes an outer face 16 on which is mounted the sleeve, coaxially.
  • the sleeve comprises two walls, one 18, exterior and the other 20, interior.
  • Two flanges 22 and 24 are also arranged at the ends of this sleeve, between the outer wall and interior so as to delimit a chamber 26, annular.
  • One of the flanges in this case, the flange 22, is equipped with a fluid supply valve 28.
  • the outer wall 18 comprises, considered concentrically, an inner face 30 and an outer face 32.
  • the interior wall 20 comprises an outer face 34 and an inner face 36.
  • the inner wall being arranged coaxially to the support cylinder, the inside face is opposite and even in contact with the outside face of the support cylinder.
  • This wall is made of a material having elastic qualities which allow a certain expansion and / or some radial retraction, of the order of a few hundredths of a millimeter to give an order of greatness.
  • the interior wall 20 of the sleeve has a nominal diameter larger than that of the support cylinder 10.
  • the inner wall of the sleeve is pressed on the support cylinder by its inner face, which causes sufficient friction forces to ensure perfect immobilization of the sleeve on the cylinder support.
  • FIGS. 2A and 2B a variant has been shown. of realization, which uses the vacuum during assembly.
  • the inner wall of the sleeve has, this time, a diameter interior lower than that of the plate cylinder, except to the right of the flanges, and the fluid is in fact a socket vacuum which allows the interior of the room 26.
  • the assembly is in this case carried out in the manner next :
  • the sleeve chamber is depressed so that the inside diameter of the sleeve is greater than the diameter of the support cylinder then the sleeve is introduced coaxially around this cylinder.
  • the vacuum is broken in the room, which has for effect of allowing the inner wall to resume its nominal inside diameter which is smaller than that of cylinder, the difference being of the order of a few hundredths of a millimeter, which therefore generates forces pressing the sleeve onto the cylinder, thus avoiding any rotation of the sleeve relative to the cylinder.
  • the interior wall 20, elastically deformable, has a nominal internal diameter greater than that of the cylinder as in the example shown in Figures 1A and 1B.
  • the pressurized fluid When the pressurized fluid is introduced into the envelope, it swells and rests on the face exterior of the interior wall which plates the sleeve against the cylinder, thus avoiding any untimely rotation of the sleeve relative to the cylinder.
  • the outer face of the outer wall is designed to receive a plate and a means of fixing it photo on this side is to have sizes 40, i.e. a set of tips 42 which, in this mode of realization, are retractable, following a generator outside of the sleeve.
  • the sizes include a connecting bar 44, arranged in chamber 26 and more particularly between the envelope 38 and the inner face 30 of the outer wall.
  • Springs 46 in this embodiment, leaf springs, are interposed between the casing 38 and the inner face 30 of the outer wall.
  • the tips 42 pass through through holes formed in the outer wall 18.
  • a groove is machined in the flanges so as to guiding the ends of the bar 44 of the sizes 40.
  • the grooves avoid a too large a retraction in amplitude which could lead at an exit of the points out of the holes which serve as guidance.
  • Figure 5 shows schematically a set of four sleeves a , b , c and d arranged on the same support cylinder by means of the mounting device according to the invention.
  • the invention also relates to a sleeve suitable for this type of mounting and more particularly a sleeve composite.
  • the elasticity of the inner wall 20 must be very weak since it only takes a few hundredths of millimeters of play to allow coaxial mounting of the sleeve on a cylinder, the surfaces being ground.
  • the present invention proposes to produce a monolithic sleeve by wrapping at least one layer of honeycomb material with a binding polymer on a mandrel 47, mechanically expandable for removal of the workpiece, whose expanded outside diameter is exactly that of a support cylinder designed to receive the muff.
  • the polymer is studied to cause shrinkage of the sleeve of the order of a few hundredths of a millimeter after polymerization.
  • the sleeve can expand in the area elastic of these few hundredths when subjected to radial pressure.
  • the sleeve is made in one piece which includes one of the two flanges, in this case the flange 24, as well as the two outer 18 and inner 20 walls.
  • the inner wall 20, which must have a certain elasticity, has a thickness less than that of the wall exterior 18 which requires great rigidity.
  • FIG. 6A there is shown so complementary matrices 48 and 50.
  • Such a layer of a conductive coating can be deposited by electrolysis.
  • Such machines generally include a roller inking, dipping, pressed against the roller a scraper ensuring the removal of the ink by excess.
  • the sleeve according to the invention can be mounted on support cylinders for two applications flexography and heliography.
