Definitions
- the present invention relates to a guide device for a printing sleeve or cylinder, in particular for flexographic printing, as well as the sleeves or cylinders equipped with this device.
- the surface of the sleeves is corrected to give it a suitable finish and above all so that the development, linked to the accuracy of the diameter, corresponds well to the development sought.
- the plate is attached to the sleeve using a double-sided adhesive. Marks are integrated into the plate and come from manufacturing with it, marks which should be made to coincide with those of the sleeve. Following the gluing of the plate on the sleeve, it is necessary to cut the double-sided adhesive which protrudes, this by performing a leveling of the best quality. Most of the time, this leveling is carried out manually by the operator, using a cutter blade, which has the immediate consequence of causing notches on the outer coating of the sleeve.
- the present invention proposes to overcome these disadvantages by means of an integrated device for guiding the laying of plates and cutting which is very practical for the user, which allows adjustments and cuts both according to generators and according to circumferences, which is of a cost price fully compatible with the price of supports, sleeves or cylinders, the amortization of which is almost immediate, which is neutral with respect to the mechanical resistance of the sleeve or cylinder, which is also self-compensated from the point of view of balancing and which is applicable to all products free of surface fibers.
- the integrated guide device for laying and cutting using a cutting tool, a plate on a sleeve or on a printing cylinder in particular in flexography, said sleeve or cylinder comprising an outer coating capable of being machined in depth is characterized in that it comprises at least one longitudinal guide, along a generator, and / or a peripheral guide, along a circumference, formed within a matrix of material of great hardness, reported in the thickness of said external coating.
- the matrix of very hard material is housed in a groove machined in the thickness of the external coating. More specifically, the groove comprises means for immobilizing the thickness of the coating, for example a dovetail profile.
- the guide has a section adapted to the profile of that of the cutting tool.
- the matrix is made of polymer material charged with metal and / or ceramic particles.
- the invention also relates to the sleeve or cylinder equipped with this device.
- FIG. 1 a perspective view of a sleeve fitted with the positioning and cutting guide device according to the present invention
- FIG. 2 a cross-sectional view of the sleeve shown in Figure 1, and - Figures 3A to 3D, a block diagram of the manufacture of such a sleeve.
- the sleeve 1 0 comprises a single longitudinal groove 1 2, two external peripheral grooves 1 4 and a central peripheral groove 1 5 so as to limit the unnecessary space requirement of the drawing.
- a plate 1 6 is reported on said sleeve, from the groove 1 5, middle peripheral.
- the sleeve simply comprises an inner layer 18 made of fibers embedded in resin, a thickness compensation layer 20 of cellular material, a belt 22 of high rigidity and an outer coating 24 of finishing resin allowing the surfacing by grinding.
- the device according to the invention is not limited to this type of sleeve embodiment but more generally applicable to all sleeves or cylinders whose outer coating is free of fibers and capable of being machined.
- the embodiment of the device is described with reference to the block diagram in FIGS. 3A to 3D.
- the sleeve 1 0 is blank, out of production, prerectified.
- a groove 26 with a dovetail profile is machined, in the preferred embodiment.
- This groove 26 is of a depth less than the thickness of the outer covering.
- the sleeve comprises for example 4 grooves, equally spaced at 90 °, for obvious reasons of symmetry.
- This groove 26 is then lined with a matrix 28 of polymer-type material loaded, for example with metal or ceramic particles so as to give it a high hardness and to resist friction. This step corresponds to that of FIG. 3C.
- the present invention proposes adding to the charged polymer, a lubricant such as graphite and / or molybdenum disulfide, these two examples cannot be considered as limiting.
- This matrix is for example rectified, simultaneously with the final rectification of the sleeve, after polymerization, to avoid any protruding particle.
- Each die is then machined in its middle part to form an integrated guide 30, the cross section of which corresponds to that of a cutter blade and the depth of which is less than the thickness of the added die 28.
- This machining is carried out using a diamond tool taking into account the hardness of the charged polymer matrix.
- the dovetail profile provides better integration of the added matrix but is not a necessity because the polymer matrix has excellent adhesion with the other resins constituting the coatings, it suffices to choose the resins compatible with those of the coating, which is within the reach of ordinary skill in the art.
- a cylinder made of metal for example aluminum alloy
- the advantage of using a polymer material is the easy implementation in the groove and the final surface condition which is capable of being rectified while offering significant hardness possibilities.
- the outer peripheral grooves are commonly used for cutting the overlapping double-sided adhesive, when the plate is positioned from the middle groove, which is the most common case.
