Definitions

  • the invention relates to a sleeve with a multilayer structure for printing presses with support rollers designed as air cylinders, in particular a sleeve for flexographic printing, with an inner tube made of reversibly stretchable plastic material, the inside diameter of which is smaller than the outside diameter of the support roller, with an elastically compressible, the radial expansion of the Inner tube in the sleeve assembly or disassembly receiving intermediate layer, and with an outer layer.
  • the invention also relates to a production method for such sleeves with the steps of producing a reversibly stretchable inner tube, applying a compressible intermediate layer on the outside of the inner tube and applying a single or multi-layer transition layer made of a pourable or foamable material of low density and / or applying an outer layer.
  • the reversibly stretchable inner tube usually consists of a relatively thin-walled plastic tube laminated with fiber inserts, which is directly surrounded by a thick-walled layer made of elastically compressible material, such as, in particular, a soft foam, which enables the inner tube to be expanded during assembly or disassembly of the sleeve or allows.
  • An outer layer can be applied directly to the elastically compressible layer, which has a surface suitable for holding the printing plates, printing plates or printing layer, or an incompressible intermediate layer, for example made of a low density potting compound or a hard foam, is arranged between the soft foam layer and the outer layer. through which the diameter of the sleeve in the radial direction can be increased by up to 100 mm without the weight of the sleeve increasing significantly.
  • the various print reports can be generated via the wall thickness of the sleeves used.
  • the variation in wall thicknesses in the radial direction is limited for printing sleeves, since with increasing sleeve thickness the deviations in diameter and concentricity increase and exact printing can no longer be guaranteed.
  • the printing industry has started to use adapter sleeves between the air cylinders and the sleeves, which are themselves provided with a compressible layer and can be pushed axially onto the air cylinder according to the air cushion principle.
  • the adapter sleeves are in turn provided on the outside with an air supply for the compressed air, around which the print motif or the printing cliché is then carried To be able to mount the sleeve on the pre-assembled unit of air cylinder and adapter sleeve.
  • the object of the invention is to provide sleeves for the printing industry which can be mounted on support rollers according to the air cushion principle and which do not show any vibration lines in the printed image even at high rotational speeds.

  • the invention is based on the finding that during the printing process with rapidly rotating support rollers and printing sleeves, the color particles adhering to the printing plates or to the printing layer, and the substrates to be printed, such as paper webs, foils, lien or the like brake the printing layer relative to the driven carrier roller.
  • This braking effect is caused by the inking unit transferring the ink particles, the surface properties of the substrate, by ink transfer rollers, doctor blades and the like. additionally reinforced.
  • the resistance opposing the rotation of the support roller and consequently the printing block increases quadratically with increasing speed of the support rollers.
  • the inventors of the present invention have now recognized that the compressible layer in the sleeve structure, owing to its material properties and because of its comparatively large radial distance from the printing cliché, can tend to yield due to the resistance forces and the braking torque introduced into the sleeve by them.
  • the yielding has an offset in the circumferential direction between the cliché and the inner tube which is firmly connected to the supporting roller.
  • the support structure provided according to the invention in the area of the compressible layer prevents this effect and at the same time ensures that if the supply pressure between the pressure cylinder and the supporting roller is too high, the repeat bridging produced with the incompressible casting compound or the rigid foam cannot yield radially into the compressible layer and can cause errors in the printed image.
  • the support structure integrated in the sleeve structure stabilizes the outer layer relative to the inner tube with partial bridging of the compressible intermediate layer in the direction of rotation, so that in the case of the sleeves according to the invention, rotational or torsional displacements in the compressible layer are prevented at the beginning.

  • the rings or radial struts can also be made of the same material as the outer layer and are preferably applied during casting, in particular rotational molding, or when the outer layer is applied. All of the aforementioned variation options ensure that the rings or radial struts penetrating the compressible layer are made in one piece with the next following layer are formed and at the same time are firmly connected to the inner tube.
  • the rings can also consist of metal, a thermoplastic or a thermoset.
  • the rings are expediently designed in several parts so that they can also be assembled if the compressible layer is first formed and subsequently replaced by e.g. turned incisions is interrupted.

Abstract

L'invention concerne un manchon à ensemble multicouches pour une machine à imprimée doté de cylindres porteurs utilisés en tant que cylindres à air, en particulier un manchon utilisé en flexographie. Ledit manchon comprend un tuyau interne (1) fabriqué dans un matériau plastique extensible, réversible, dont le diamètre interne est inférieur au diamètre extérieur du cylindre porteur. Ledit manchon comprend de plus une couche intermédiaire (2) élastique, compressible et qui reçoit l'extension radiale dudit tuyau interne lors du montage dudit manchon, ainsi qu'une couche extérieure (3). L'invention concerne un procédé de production desdits manchons. Le manchon de l'invention est caractérisé en ce qu'une structure de soutien (5) est intégrée dans l'ensemble manchon entre le tuyau interne et la couche extérieure. Ladite structure pénètre entièrement dans le sens radial la couche intermédiaire compressible (2) sur au moins une partie, et permet de stabiliser la couche extérieure (3) par rapport au tuyau interne (1) dans le sens de la circonférence et/ou dans le sens radial. Grâce au franchissement partiel de la couche intermédiaire compressible, cette dernière est déchargée des forces dans le sens de la rotation. De ce fait, on peut éviter l'apparition de rayures dues aux vibrations dans l'image d'impression.
