Definitions

  • the present invention relates to a device for the localized distribution of electrifiable materials, a printing installation equipped with at least one of these devices allowing continuous overprinting of patterns of non-fixed electrifiable materials, and the decorated supports obtained on this installation.
  • Devices for distributing electrifiable materials on any support previously covered with an adhesive layer intended to receive said materials are well known. These devices essentially consist of a vibrating screen, the lower grid of which, connected to a high-voltage generator, creates an electrostatic field thanks to which the electrizable materials, whether cut fibers or flocs, or any other particulate matter are directed perpendicular to the support to be decorated and are installed on the areas of said surface previously covered with adhesive.
  • Some of these devices are provided with fixed partitions making it possible to divide them into different compartments containing for example, in the case of flocking, cut fibers of different colors, which makes it possible to obtain, in a single operation, flocked effects of different colors.
  • the current processes for applying electrifiable materials require the following steps: electrostatic application of said materials to the adhesive-coated support, fixing most often by thermal means, of said materials on the support and cleaning by suction-threshing or electrostatic process. or by the two processes combined, electrifiable materials which are not fixed.
  • the current process of applying electrifiable materials has the disadvantage of dispersion: Indeed, electrifiable materials, generally distributed by a screen with a rectangular grid, due to the electrostatic phenomenon, a back and forth movement between the grid polarized and the article to be decorated which is fixed on a metal plate connected to earth. In the center of the grid, the electrifiable materials have a vertical back and forth movement. On the edges of the grid, they tend to go outwards under the influence of the lines of force of the magnetic field. Arrived outside, these electrifiable materials are attracted by any surrounding metallic mass, resulting in an annoying dispersion for screen printing operations which are carried out nearby.
  • the purpose of the present invention is to remedy this drawback, and to enable the continuous application, and on the same installation, of the application of electrifiable materials and the overprinting of the relief pattern thus obtained, without it it is necessary to proceed to the intermediate fixing step of the electrifiable materials.
  • the present invention makes it possible to avoid almost completely the dispersion of the electrifiable materials and allows the incorporation of a flocking cell in a mechanical screen printing system without disturbing the functions thereof and avoiding clogging of the printing frames by the electrifiable materials. in dispersion.
  • the invention firstly relates to a device for localized distribution of electrifiable materials of the type consisting of a vibrating screen, provided with partitions, the lower grid of which is connected to a high-voltage generator and the originality of which is that that said partitions are constituted by a series of independent removable cylindrical elements, made of non-conductive material, of parallel axes, of uniform or variable diameter, arranged perpendicular to the screen of the screen, and the maintenance of which in desired position is ensured by simple contact of said cylindrical elements along their generatrices, the outer row of said elements also being in contact along the generatrices of the elements with the internal walls of the screen.
  • the first of these covers connected to a supply hopper for electrifiable materials, is intended for be exposed a part of the cylindrical elements according to a surface essentially corresponding to that of the pattern which it is desired to apply, the other cylindrical elements being covered, while the second cover, complementary to the first and connected to a suction device, is provided to cover at least the part of the cylindrical elements previously discovered.
  • the introduction of electrifiable materials will be limited to only the cylindrical elements corresponding to the surface which it is desired to coat. This operation is carried out before the start of the application process of electrifiable materials and will only need to be renewed when the reservoir constituted by the tubes filled with electrifiable materials has emptied in the succession of application operations.
  • the reservoir constituted by the tubes filled with electrifiable materials will be protected against the action of the suction device by the second cover, leaving only the cylindrical elements hidden by the first cover exposed.
  • a judicious choice of cylindrical elements of different diameters is sufficient to adapt them to the opening made in the first cover, this opening corresponding substantially to the pattern that it is desired to obtain.
  • This device enables significant savings to be made in electrifiable materials compared to existing devices; when the device is powered up, almost all of the electrifiable materials will settle on the part of the support previously covered, according to the chosen pattern, with a layer of adhesive.
  • a localized distribution device is provided side by side provided with the second cover covering the surface corresponding to the pattern and connected to a first suction device, and a second similar device, but without distribution, and connected to a second suction device covering the surface corresponding to the pattern.
  • the pigging station immediately preceding the application device is of particular importance since it is it which conditions the supply of adhesive essential for fixing the electrifiable materials applied according to the distribution device located above.
  • the support it is indeed necessary to provide the support to be coated with a layer of adhesive which, while being well anchored in said support, has a uniformity and a thickness sufficient to ensure implantation and then fixing these electrifiable materials.
  • the invention therefore also relates to the scraping head which comprises two scrapers, working in opposite directions at an angle of approximately 70 ° relative to the scraping plane, one of these scrapers made of a material with a hardness of about 70 ° Shore, having a rounded lower end and the other doctor blade, made of a material with a hardness of about 60 ° Shore, having a lower bevel cut.
  • the adhesive is first applied in depth using the scraper with a rounded end and then the uniform coating is ensured using the other scraper at the end. bevel cut.
  • the invention also relates to the overprinted relief patterns obtained by using the printing installation comprising the device for localized distribution of electrifiable materials according to the invention.
  • FIGS. 1 to 3 2 represents the vibrating screen, 3 the grid, 4 the cylindrical elements, 5 the first cover connected to the feed hopper 6, and 7 the second cover connected to the suction hood 8.
  • the device according to the invention consists of a vibrating screen 2, the lower grid 3 of which is connected to a high-voltage generator (not shown). Inside the screen 2 and resting on the grid 3, are arranged the cylindrical elements 4, removable, independent, with parallel axes. These cylindrical elements are made of a non-conductive material such as, for example, polyvinyl chloride.
  • the elements 4 shown in the figures all have the same diameter, but they can of course have diameters different from each other. Maintaining them in the desired position is ensured by contact with neighboring elements along their generatrices.
  • the elements 4 forming the outer row of the assembly are also in contact with the inner walls of the screen 2 according to their generatrices.
  • Figure 2 shows the device of Figure 1 when it is used for loading electrifiable materials.
  • a cover 5 is placed, connected to the feed hopper 6.
  • the opening of the hopper 6 adapts to a cutout 9 made in the cover 5.
  • This cutout carried out essentially along the outline of the pattern which it is desired to cover with electrifiable materials leaves uncovered a corresponding number of cylindrical elements 4 and mask all others; the diameters of the various cylindrical elements left uncovered are chosen such that the cutout 9 of the cover 5 leaves uncovered only entire sections of cylindrical elements.
  • the support 10 was previously, as it is known per se, coated with an adhesive layer according to the same pattern and placed in a conventional manner, and not shown under the localized distribution device, in relation to the cutout 9 of the cover 5.
  • the grid 3 of the screen 2 is then tensioned in a conventional manner and the electrifiable materials contained in the cylindrical elements corresponding to the cutout 9 of the cover 5 are projected onto the part of the support 10, coated with adhesive according to the design of the motif.
  • FIGS 4 and 5 show the scraper head according to the invention to achieve this goal.
  • 11 generally designates the scraper head which comprises the two doctor blades 12 and 13.
  • the scraper head 11 of the rocking type is integral with the movable shaft 14, connected to conventional means (not shown) allowing its transverse movement in the scraper plane 15, back and forth, and the reversal of the position of the doctor blades relative to said doctor blade 15 at the end of the stroke.
  • the scraping head 11 in the shape of an inverted U comprises, on one of the branches of the U a first doctor blade 12 with rounded lower end, made of rubber or any other suitable material with a hardness of about 70 ° Shore and, on the other branch of the U, a second doctor blade 13 whose lower end is cut in a bevel, also made of rubber or any other suitable material but with a hardness of about 60 ° Shore.
  • doctor blades 12 and 13 The upper part of the doctor blades 12 and 13 is held, in a manner known per se between the jaws 16 and 17 which ensure perfect solidarity of the assembly.
  • the doctor 12 works, in the direction of the arrow F, achieving, thanks to its rounded end, a deep impregnation of the support; the doctor 12 works at an angle of about 70 ° relative to the doctor plane 15.
  • the scraper head 11 At the end of the race, the scraper head 11 having tilted, it is the scraper 13 which works, in the direction of the arrow F ′, achieving, thanks to its lower end at a bevel, good distribution and good coating of the adhesive; doctor blade 13 also works at an angle of about 70 ° with respect to doctor blade 15.
  • the scraping speed varies between 0.15 and 0.60 m / second.
  • two or four successive passages of the doctor blades are carried out.
  • the raising of this frame (not shown) to make room for the next frame is advantageously done by pivoting along a horizontal axis, which makes it possible to ensure the gradual detachment of the surface covered with adhesive.
  • the scraping station is mechanically and electrically synchronized with the other stations of a rotary vane printing machine or of an endless belt machine, by insertion in place of another station of the machine.
  • the three A4 stations, A5 and A6, preceding the print heads being equipped as follows: the first A4 station is constituted by the scraping head 11 making it possible to apply the adhesive to the support according to the pattern that the '' it is desired to obtain, the following station A5 is constituted by a localized distribution device according to the invention, previously filled with electrifiable materials according to the pattern to be produced using the first cover, then provided with the second cover and connected to a device aspiratkn, and the following station A6 of the same device but without distribution of electrifiable materials and connected to the extractor hood, the print heads B1, B2, B3, B4, B5 and B6 then allowing the desired drawing to
