Definitions
- the invention relates to a method for manufacturing a printing blanket obtained by assembling a plurality of layers and a blanket thus obtained.
- Blankets of this type are produced by coating successive layers of elastomers on fabric reinforcements. These layers are dried, assembled and vulcanized.
- the materials used and the methods of manufacturing these blankets involve the use of chemicals dangerous to man and the environment such as solvents, vulcanizing agents, plasticizers and decomposition products during vulcanization as well than carbon black. Indeed, these products contain in particular carcinogenic substances or supposed to be carcinogenic, such as plasticizers, carbon black and decomposition products, substances dangerous for reproduction and mutagenic substances such as in particular vulcanizing agents, allergenic substances , harmful and flammable like solvents and toxic and corrosive substances.
- the known blankets manufactured according to known methods keep a residual solvent level whatever the drying precautions taken by the manufacturers. These residual solvents can cause porosity and untimely sagging during storage and operation. It should be noted that sagging is one of the serious functional defects of blankets.
- the known blankets still have the disadvantage of developing vapors and odors which can inconvenience users. in case of confined storage.
- these blankets according to the state of the art can hardly be eliminated at the end of life, in particular because of their chlorine and sulfur content.
- the object of the invention is to provide a process and blankets obtained according to this process, which make it possible to eliminate the danger to the environment and to humans from the abovementioned manufacturing processes and blankets produced according to these processes.
- the method according to the invention is characterized in that the different layers are fixed to each other by means not involving the use of solvents, in particular by a treatment of the Corona type, of ionization or flaming.
- elastomers which do not contain thermal crosslinking agents and are of thermoplastic nature are used for the production of the layers.
- the production of the elastomer layers is carried out dry without the use of solvents, advantageously by extrusion.
- a layer of thermoplastic material of a predetermined length, is wound around a sleeve forming a support, after having bevelled the ends of this layer , by superimposing the beveled ends and creating a tubular structure by assembling the ends by appropriate heating, the tubular structure thus obtained being able to serve as a support for the production of another tubular layer.
- the lithographic layer of a sleeve-shaped blanket is crosslinked by radiation, then, if necessary rectified and sanded.
- a compressible tubular layer is produced by giving it the possibility of expansion during hot assembly of the ends, thanks to expandable microspheres, previously incorporated into the layer.
- FIGS. 1 to 6 are sectional views of six embodiments of a blanket according to the invention.
- FIG. 7 is a schematic view illustrating a method of producing a blanket according to the invention.
- a multilayer blanket according to the invention which does not constitute a danger to man and to the environment is advantageously produced by extrusion of successive layers of elastomers assembled with reinforcements and other layers of elastomers or polymers assembled in a shell downstream of one extruder.
- the fabrics used to assemble the layers are caused to adhere to the elastomer layers by treatment of the Corona type or by ionization or flame treatment to avoid the use of solvents.
- Adhesives without solvents of the pressure-sensitive type may also be used.
- the elastomer layers are produced by dry methods without the use of solvents and in particular by extrusion.
- the materials used have the ability to become fluid at high temperature and therefore allow the creation of good quality thin films, in particular by extrusion.
- tubular blankets comprising one or more compressible layers, one or more reinforcing layers, a lithographic layer, associated, where appropriate, with a support layer, with other functional layers or with layers of filling.
- the tubular structure can also be obtained by direct extrusion of one or more successive concentric layers on the sleeve having an internal support and in progress.
- the direct extrusion can be of the ribbon type or of the annular type. As a variant, co-extrusion is also possible.
- the invention is applicable to all blankets, the thickness of which must be uniform, regardless of the means used to produce a lithographic surface ensuring good print quality.
- the invention thus makes it possible to obtain, compared to the blanket without rectification, a gain in precision by a factor of 2, namely an overall thickness tolerance of +/- 0.01 mm against +/- 0.02 mm approximately from the state of the art.
- the invention also makes it possible to obtain a reduction in the total thickness of the blanket. Indeed, in separating the different functions to be performed by the blanket, and by conferring these functions on specific layers, an optimal blanket structure can be established by assembling layers of fabric, compressible layers and the lithographic layer. It has been found that the use of a beam or a woven wire or grid makes it possible to replace several fabrics and thus provides a reduction in thickness.
- the use of an aramid-type wire beam for example saves the relative thickness of at least one ply of fabric.
- the gain is at least 0.5 mm.
- the beam used in the context of the invention is itself thinner than the fabrics it replaces.
- the beam replaces reinforcing fabrics which contribute to the compressibility of the blanket, this compressibility is maintained despite the removal of the fabrics by rendering the polymer layer on the back, compressible accordingly.
- the invention makes it possible to produce a blanket of a practically uniform thickness of 1.00 to 1.30 mm while retaining the breaking strength of known blankets which, for the most part, have a thickness of 1.7 to 2 m.
- the invention allows the production of a blanket comprising, from inside to outside the following layers: a layer of slightly compressible polymer, an aramid beam or the equivalent in warp direction, a main compressible layer, a stabilization fabric with , for example, monofilaments in the weft and flexible warp direction and a lithographic layer.
- the stabilization fabric can be replaced by a layer of hard polymer possibly reinforced with fibers and, in a second variant, the compressible layer or layers can be made anisotropic by incorporating fibers oriented in the plane of the blanket.
- Figures 1 to 6 show the structure of six advantageous embodiments of a blanket according to the invention, having a reduced thickness.
- the blanket shown in FIG. 1 comprises, from the interior to the exterior, a layer of slightly compressible polymer 1, a compressible layer 3 in which the beam 2 is integrated, a stabilization fabric or reinforced hard layer 4, and a lithographic layer 5.
- the blanket has a thickness of approximately 1.2 mm.
- the compact polymer layer 6 is removed with respect to the blanket of FIG. 1, which makes it possible to reduce the thickness of the blanket to approximately 1.1 mm.
- FIG. 3 shows a blanket in which the beam 2 is integrated into the polymer layer 1 on the back of the blanket, the compact polymer layer 6 also being removed.
- the thickness of the blanket is approximately 1.2 mm.
- the blanket of Figure 4 corresponds to that of Figure 3, with the difference however that the beam 2 is integrated in the compressible layer in the upper part thereof.
- the thickness of the blanket is 1.1 mm.
- the blanket shown in Figure 5 has an even smaller thickness of about 1 mm thanks to the fact that the layers 1 of compressible polymer and layer 6 of compact polymer have been omitted, the assembly 2 being integrated into the compressible layer 3 at the top thereof.
- FIG. 8 shows a blanket comprising on the back a compressible layer 3 with the beam integrated in the upper part thereof, an anisotropic compressible layer 7 and a lithographic layer 5. The thickness of this blanket is also about 1 mm.
- fine particles for example glass microbeads or polymer or ceramic powders.
- glass microbeads good surface water spreading properties are obtained.
- the inlay of the particles can also be made on the surface of the back layer if it is made of a polymer material. This inlay makes it possible to advantageously reduce and the coefficient of friction of this surface. A low coefficient of friction is very useful to facilitate fixing to the cylinder of the printing machine.
- the encrusted particles are preferably spherical in nature and have diameters preferably between 1 and 100 microns.
- the roughness of the surface of the plunger cylinder is one of the parameters of the quantity of particles transported.
- the tank can be animated with a vibrating movement to guarantee a regular deposit on the surface of the plunger grille cylinder.
- a scraper device for the plunger cylinder can also be provided to measure the quantity of particles deposited and encrusted on the surface of the blanket.
- the inlay described here can be done on the surface of a polymer film previously extruded and, if necessary, rectified by simple reheating of the surface thereof by means known per se, such as ramps infrared, and passage of the blanket with its layer of polymer heated on the surface between the cylinders of the calender of FIG. 7.
- the invention also ensures a reduction in cost insofar as a thin blanket requires for its production a lesser quantity of material which is the most important item in the cost price.
- the invention allows a further reduction in the quantities of waste. In fact, thinner blankets mean less waste to be eliminated.
- by encrusting particles on the surface of the lithographic layer, or the layer on the back one can obtain a desired microheterogeneity of surface and / or reduce the friction of the blanket on the support.
- the invention makes it possible to produce "ecological" blankets, that is to say constituting no risk for man and for the environment.
