Definitions

  • the present invention essentially relates to an elastic and compressible printing element, this element constituting what is called a blanket and can be fixed on the surface of cylinders that are found in printing machines.
  • printing blankets currently used in printing machines essentially comprise a lithographic layer allowing the transfer of information from the blanket cylinder onto a strip of paper, and a compressible structure consisting of a layer of cellular rubber taken up sandwich between two fabric layers.
  • Document FR-A-2 461 596 has also proposed a blanket essentially comprising a lithographic layer, a layer of cellular rubber and a stabilization or base layer composed of several layers of tissue adhered with neoprene.
  • such a blanket is likely to generate high pressures in the interval between two cylinders carrying the blankets, while this should be avoided so as not to alter the structure of the blanket, and such a blanket can also present risks of shearing, that is to say of lateral displacement of the blanket material, which leads to the drawbacks mentioned above.
  • the present invention aims to remedy all the above drawbacks by providing a blanket which will have no tendency, when compressed, to cause lateral displacements of the material which constitutes it so that the print quality and the scrolling of the paper strip will remain satisfactory, and which will always exhibit neutral dynamic behavior under the effect of a compression force.
  • the subject of the invention is an elastic and compressible printing element of the type comprising a lithographic or printing layer with which is associated a compressible structure with three layers comprising a fabric layer interposed between two layers of cellular rubber. , characterized in that a layer of hard elastomer is interposed between the lithographic layer and the layer of cellular rubber closest to the lithographic layer and in that said layer of cellular rubber has a modulus of elasticity of between approximately 0, 2 and 50 megapascals (MPa) and which is higher than that lower and between approximately 0.1 and 25 MPa of the second layer of cellular rubber located on the other side of the fabric layer.
  • MPa megapascals
  • said second layer of lower modulus of elasticity is associated with a base layer of fabric or other reinforcing material.
  • the thickness of the fabric layer is between approximately 0.1 and 1 mm, and the thicknesses of the two layers of cellular rubber are each between 0.1 and 0.8 mm.
  • the thickness of the tissue layer is 0.35 mm
  • the thickness of the layer of cellular rubber with a lower modulus of elasticity is 0.5 mm
  • the layer of cellular rubber to higher modulus of elasticity is 0.45 mm.
  • the thickness of the abovementioned layer of hard elastomer is between approximately 0.5 and 0.05 mm. According to a preferred embodiment, this thickness is equal to 0.15 mm.
  • the elastic modulus of the cellular rubber layer located on the side of the lithographic layer is 10 MPa, while the elastic modulus of the other cellular rubber layer is 5 MPa .
  • the percentage by volume of the gas enclosed in the two layers of cellular rubber is between approximately 10 and 80%
  • the percentage by volume of the gas enclosed in the two layers of cellular rubber is equal to 30% for the layer of higher modulus of elasticity and 35% for the layer of modulus of elasticity more low.
  • the invention also relates to the cylinders equipped with a printing element forming a blanket meeting the above characteristics.
  • Figure 1 is an enlarged sectional view of a printing blanket according to the invention.
  • Figure 2 is an enlarged sectional view of another embodiment of the blanket according to this invention.
  • FIG. 3 schematically and partially illustrates two blankets according to this invention, in the compressed state, and carried respectively by two cylinders between which passes a strip of paper, the assembly being related to a reference system with axes of orthogonal coordinates where l he abscissa axis coincides with the direction of the paper strip and where the ordinate axis intersects the abscissa axis in the center of the compressed area of the two blankets.
  • FIG. 4 represents three curves illustrating, in millimeters, the lateral displacement of the material constituting the blanket on either side of the center O of the compression zone - deformation visible in FIG. 3, as a function of the distance, from this point 0 and along the abscissa axis OX in FIG. 3, these three curves corresponding respectively to a blanket as commonly used today and which will be called hereinafter blanket of the prior art, a blanket according to document FR-A-2 461 596, and a blanket according to the invention.
  • FIG. 5 also represents three curves illustrating the relative pressure in the interval between blankets, for the three blankets above, as a function of the position, on the axis of the abscissae OX, relative to the center O of the pressure zone .
  • an elastic and compressible element or printing blanket successively comprises an outer lithographic or printing layer 1, a layer of hard elastomer 2, a layer of cellular rubber 3, a layer of fabric or the like 4 and another layer 5 of cellular rubber.
  • the blanket also has a base layer 6 of fabric or other suitable reinforcing material.
  • the base layer 6 When fixing the blanket to a cylinder (not shown), the base layer 6 will be applied to the peripheral surface of this cylinder, while, in the case of the blanket of FIG. 1, the base layer applied to the cylinder consists of the layer of cellular rubber 5.
  • the layers of cellular rubber 3 and 5 can be identical or different in terms of their modulus of elasticity in particular.
  • the layer 3 located on the side of the lithographic layer 1 will have a higher modulus of elasticity in compression and between approximately 0.2 and 50 MPa, while the layer 5 forming the base layer (FIG. 1 ) or associated with base layer 6 (FIG. 2) will have a lower modulus of elasticity of between approximately 0.1 and 25 MPa.
  • the modulus of elasticity of the layer 3 can be equal to 10 MPa, and the modulus of elasticity in compression of the other layer 5 of cellular rubber can be equal to 5 MPa.
  • the difference in elastic modulus between the two layers of cellular rubber 3 and 5 can be obtained by varying the percentage by volume of the gas enclosed in the two layers, preferably in closed cells, as shown diagrammatically on the figures.
  • the percentage in question may be equal to 30% for layer 3 of higher elastic modulus, and to 35% for layer 5 of lower elastic modulus.
  • the thicknesses of the two cellular rubber layers 3 and 5 can each be between 0.1 and 0.8 mm. We can thus provide a thickness of 0.45 mm for layer 3 and a thickness of 0.5 mm for layer 5.
  • the thickness of the fabric layer or the like 4 sandwiched between the two layers of cellular rubber 3 and 5 may be between approximately 0.1 and 1 mm and for example be equal to 0.35 mm.
  • the thickness of the layer 2 of hard elastomer it will be between approximately 0.5 and 0.05 mm and will preferably be equal to 0.15 mm.
  • the first column indicates the thicknesses in millimeters of the layers.
  • the second column appear the successive layers of a blanket according to the invention and as shown in FIG. 2.
  • the third column appear the successive layers of a blanket according to the prior art, which comprises, as mentioned at the beginning from this description, a layer of cellular rubber interposed between two layers of tissue, while the blanket of the invention comprises, conversely, a layer of tissue interposed between two layers of cellular rubber.
  • the layers of the blanket appear according to document FR-A-2 461 596 which, it should be remembered, comprises only a single layer of cellular rubber and a base layer formed by several layers of fabric bonded with neoprene.
  • a hard elastomer layer is associated with the lithographic layer.
  • FIG. 4 represents the displacement of material or the shear C as a function of the distance D relative to the center O of the pressure zone, and this for the three blankets of the table above.
  • curve C1 which corresponds to the blanket of the invention is substantially flat, that is to say that practically no lateral movement of the blanket material according to the invention does not occurs, under compression, unlike the blanket of the prior art (curve C2) and the blanket according to document FR-A-2 461 596 (curve C3), which however has a less marked tendency to shear than the blanket according the prior art (curve C2).
  • the print quality and the movement of the strip of paper P passing between two blanket cylinders will be very greatly improved due to the absence of lateral displacement or surface shear.
  • the blankets of the invention will have a neutral dynamic behavior on rolling on the strip of paper P.
  • the blanket according to the invention is remarkable in particular from the point of view of the gain in compressibility and the absence of shearing, which has an advantageous effect on the quantity of printing of the paper, on the throughput or the movement of the paper, and on the longevity of the blanket, this essentially thanks to the provision in said blanket of a layer of fabric sandwiched between two layers of cellular rubber with identical or different modulus of elasticity.
