Definitions

  • the invention relates to an apparatus for applying liquid or viscous materials to a web in connection with the employment of a roller squeegee.
  • the object of the invention is to eliminate the disadvantage mentioned above. This is attained through the arrangement of a blade squeegee upstream of the roller squeegee and by feeding the ink upstream of the blade squeegee.
  • a further advantage of the invention is manifested in its application to a cylindrical stencil screen-printing machine. Only a definite amount of ink still reaches the roller squeegee in this case specifically the amount which was pressed by the preceding blade squeegee into the openings of the stencil. The roller squeegee then presses the ink into such amount of material.
  • FIG. I is a cross-section illustrating the application of the invention to a cylindrical stencil screen-printing machine.
  • FIG. 2 is a cross-section illustrating the application of the invention in a non-stencil machine.
  • FIG. 3 is a cross'section illustrating a modification of the device of FIG. 1.
  • printing ink is supplied through an ink tube 5, passes out through openings 9 and forms an ink sump 4 upstram of a blade squeegee 3, as seen in the direction of rotation of a cylindrical stencil 1, which blade squeegee is attached to ink tube 5.
  • Blade squeegee 3 which advantageously contacts the stencil outside the area of contact of stencil l and a web of materials 6, wipes clean the inner side of stencil 1 and, at the same time, presses ink 4 into the openings of stencil 1.
  • Web 6 contacts a printing support 7 running over drivable rollers. The web takes along stencil 1 owing to the pressure exerted thereon by roller squeegee 2.
  • Roller squeegee 2 is forced against the inner surface of stencil l by pressure, in this case by means of a magnet bar 8 arranged under printing base 7, but the application of pressure could also be effected mechanically.
  • Stencil I thus set in rotation, conveys ink 4 situated in its openings to roller squeegee 2, which presses it into web 6.
  • FIG. 3 shows the contact of blade squeegee 3 with stencil 1 within the contact zone B.
  • the arrangement of FIG. 3 makes it possible to obtain certain printing effects, e.g., softer outlines of the pattern, while rather sharper outlines are obtained with the arrangement of FIG. 1.
  • squeegee 3 in the embodiment of FIG. 3 is held in a guide 13, which is attached to ink tube 5, and consists of magnetizable material.
  • the pressureapplication of blade-squeegee 3 and roller squeegee 2 is effected by means of a magnet system 12 arranged below printing base 7 and consisting of a magnet bar or a magnet roller.
  • the invention is not restricted to the employment in connection with screen-printing stencils, such as round, band and flat stencils.
  • the invention can also be employed with success in area 1 application of viscous materials to a web, as illustrated, for example, in FIG. 2.
  • the coating material e.g., an adhesive
  • the blade squeegee consists of a loop 3' of thin elastic material, e.g., nickel, and a magnetizable rod 10 inserted into loop 3'.
  • Rod 10 is pressed against web 6 by means of a magnet bar 8 arranged below printing base 7, so that the coating material is wiped off in a thin film onto the web.
  • the coating material which now adheres to the surface of.web 6 is then pressed deeper into the web by roller squeegee 2 that is pressed by magnet bar 8 against the web.
  • Loop 3' is attached with its upper end to a beam 11 that is held in a vertically adjustable position in a machine frame that is not illustrated in the drawings. Accordingly, by varying the distance between beam 11 and web 6, the coating material can be wiped to a greater or smaller extent by the blade squeegee and the thickness of the coating varied, or it is possible to obtain a coating of the desired thickness.
  • separate magnet bars 8 and 8' are provided for each of the blade squeegee and also for roller squeegee 2. However, it is also possible to provide only a short distance between the two squeegees and to apply pressure to the two squeegees by means of a single magnet bar.
  • the ratio of pressure of the blade squeegee and the roller squeegee depends in this case largely on the magnetic properties of the materials that are employed in roller squeegee 2 and rod 10 of the blade squeegee and on the cross sections selected.
  • a printing apparatus for applying a liquid or viscous printing material to a traveling web comprising:
  • a moving printing base supporting and transporting a web; a stencil screen mounted in contact with said web,
  • said screen having therein perforations; means for supplying said liquid or viscous printing material to a position on said stencil screen; blade squeegee means mounted to permanently contact said stencil screen for pressing said liquid or viscous printing material into but not through said perforations in said stencil screen; and
  • roller squeegee means permanently contacting said stencil screen at a position downstream of said blade squeegee means, as viewed in the direction of travel of said web, for pressing said liquid or viscous printing material positioned in said perforations through said perforations onto said web.
  • said stencil screen comprises a cylindrical stencil screen mounted for rotation in contact with said web, said blade squeegee means and said roller squeegee means being positioned to contact the interior of said screen.
  • said blade squeegee means and said roller squeegee means are formed of magnetizable material, and further comprising magnet means positioned on the side of said web opposite said blade squeegee means and said roller squeegee means'for causing said blade squeegee means and said roller squeegee means to be pressed toward said web.
