Definitions

  • the present invention relates to a cylinder in particular for printing and its manufacturing process.
  • the object of the invention is therefore to solve these problems by proposing a cylinder in particular for printing which is extremely resistant to deformation and as light as possible.
  • the subject of the invention is a cylinder, in particular a printing cylinder, characterized in that it comprises a first internal tubular sleeve adapted to cooperate with a support shaft and a second external tubular sleeve arranged around the first and coaxial with the latter, the outer surface of which is adapted to receive a working coating, the two sleeves being connected by at least one radial spacer, and in that the first and second internal and external tubular sleeves and said at least one radial spacer, are made of fiber-reinforced resin.
  • the first and second sleeves can be connected by several radial spacers.
  • the or each spacer is in one piece with the sleeves.
  • the invention also relates to a method of manufacturing a cylinder as described above, characterized in that fibers are wound around a first cylindrical cavity so as to form a first part of structure of fibers corresponding to the first internal sleeve, there is around a portion of this part of the structure, a second imprint delimiting at least one free space determining the thickness and the height of said at least one radial spacer, in which are wound fibers so as to form a second part of fiber structure corresponding to the spacer and the fibers are wound around this second imprint so as to form a third part of fiber structure corresponding to the second outer sleeve.
  • this cylinder 1 has a first internal tubular sleeve 2 adapted to cooperate with a shaft support and a second external tubular sleeve 3 disposed around the first sleeve and coaxial with it.
  • the external surface of the second external tubular sleeve 3 is adapted to receive a working covering and the sleeves 2 and 3 are connected by at least one radial spacer 4.
  • This spacer is advantageously of one piece with the sleeves and as shown in this figure, this spacer can be provided at one of the ends of the sleeves.
  • the cylinder according to the invention consists of resin reinforced with fibers, for example glass.
  • the glass fiber structure can be produced by filament winding, this process being illustrated in this figure 1.
  • This process consists in winding around a first tubular impression 5, fibers so as to form a first part of fiber structure corresponding to the first internal tubular sleeve 2, to arrange around a portion of this first part of fiber structure , a second cavity 6 comprising a tubular mandrel 7 and a stop ring 8, delimiting between them a free space determining the thickness and the height of the radial spacer.
  • a second cavity 6 comprising a tubular mandrel 7 and a stop ring 8 delimiting between them a free space determining the thickness and the height of the radial spacer.
  • We then wind fibers in this free space so as to form a second part of fiber structure corresponding to the spacer and finally we wind the around this mandrel 7 of the fibers so as to form a third part of the fiber structure corresponding to the second external tubular sleeve 3.
  • This fiber structure is then embedded in resin using known techniques, these fibers can be pre-impregnated with resin or not, then the resin is hardened in a manner known per se before the withdrawal of the mandrel.
  • a cylinder according to the invention may also include an internal tubular sleeve 9 and an external tubular sleeve 10 connected by a radial spacer 11 disposed in the plane of symmetry of the sleeves.
  • This spacer is always advantageously made in one piece with the sleeves, for example in fiber-reinforced resin.
  • the manufacturing method of this embodiment of the cylinder according to the invention consists in winding fibers around a first cylindrical cavity 12 so as to form the fiber structure of the first internal tubular sleeve 9, to be arranged around a portion from this first sleeve an imprint 13 comprising two mandrels 14 and 15 defining between them a free space determining the thickness and the height of the spacer, space in which fibers are wound so as to constitute the fiber structure of this spacer and finally to wind around these mandrels fibers so as to constitute the fiber structure of the second sleeve.
  • This fiber structure is embedded in resin, and this resin is then hardened, before the mandrels are removed.
  • FIG. 3 represents a third embodiment of a cy lindre according to the invention
  • this can also consist of a first internal tubular sleeve 16 around which is disposed a second external tubular sleeve 17 coaxial with the first, these sleeves being connected by several radial spacers, for example two 18 and 19 as shown in this figure.
  • These radial spacers can be arranged regularly along these sleeves so as to improve the mechanical strength of the cylinder.
  • the method of manufacturing this sleeve always consists in winding around a first cylindrical cavity 20 fibers so as to constitute the fiber structure of the first tubular sleeve 16, in having around this first structure a second cavity comprising two mandrels 21 and 22, delimiting between them a free space in which is placed a core 23 whose lateral faces delimit with the facing surfaces of the mandrels 21 and 22 respectively, two free spaces in which fibers are wound so as to constitute the fiber structures of the two spacers 18 and 19 and finally to wind fibers around the mandrels 21, 22 so as to constitute the fiber structure of the second external tubular sleeve 17.
  • the external and internal surfaces of the mandrels can be slightly conical so as to facilitate their removal from the cylinder after the resin has been hardened.
  • the or each free end of the cylinder for example 1 can also be provided with an end flange 24 thus blocking this end or each free end of the cylinder.
  • the cylinder according to the in-vention can be arranged around an expandable fixing shaft such as those manufactured for example by the company ACHARD-PICARD, REMY & Cie.
  • the ends of the internal sleeve are flared and adapted to cooperate with clamping corners on a support shaft.
  • This cylinder made in one piece for example by filament winding of glass fibers, or in other composite materials, can for different applications, be associated in its manufacture with other elements such as copper, aluminum, nickel or carbon.
  • a screened ink cylinder laser engraved, comprising glass fibers, a projection of ceramic on the external surface of the external sleeve and an etching of this ceramic layer.
  • a screened inking cylinder with traditional engraving comprising glass fibers on which copper is deposited which is engraved and then chromed.
  • a plate cylinder comprising glass fibers and a rubber coating if necessary.
  • a bubbler cylinder comprising glass fibers and a rubber coating.
  • a printing cylinder comprising glass fibers and an engraved and chromed copper coating.
  • a pressure cylinder comprising glass fibers and a rubber coating.
  • the cylinder according to the invention is therefore particularly well suited to the rotary printing sector, either in gravure printing or in flexography, for printing for example d food packaging. Indeed, these printing techniques require, for the different formats, a very frequent change of cylinders which are currently constructed of steel and which require for their handling motorized lifting means and a significant workforce.
  • the cylinder according to the invention a manufacturing cost much lower than those of the prior art, also has a much lower weight, which results in greater ease of operation for the establishment of this cylinder in the printing elements, greater ease of drive and therefore energy saving, the elimination in most cases of motorized lifting means specially adapted for this purpose, greater ease of storage, a possibility of re-use the cylinders and greater safety when handling them.
  • the cylinder according to the invention is fixed by corners on a drive shaft, these can cooperate with surfaces of complementary shape to the ends of the first internal sleeve.
  • the or each end flange is then fixed only on the outer sleeve so that only the inner sleeve tends to deform.
  • fibers of a material other than glass can also be used for the manufacture of a cylinder according to the invention.
  • the free spaces or cells defined between the sleeves and the spacers can be filled with an amorphous material of low density, such as for example an expanded material, making it possible to eliminate the phenomena of acoustic resonance and mechanical vibrations when the cylinder rotates. high speed.
  • an amorphous material of low density such as for example an expanded material
