Definitions

  • the present invention is therefore based on the object of shortening or almost eliminating the dry downtimes for the surface of the flat screen stencil in order to prevent clogging of the stencil screen and to keep it always moist.
  • the inventive device for performing the method consists of the features listed in the characterizing part of claim 2.
  • FIGS. 1 to 5 are combined all three doctor blades to a common squeegee device 123, and are movably supported in a known manner, when the screen printing stencil 4 g during the applying, svorganges resting or the squeegee device 123 is arranged stationary, when the Screen printing stencil 4 moves. With each squeegee process there is a back and forth movement of one of the two parts.
  • a pivot linkage 50 which can be moved with a movement cylinder 5 (power cylinder) and is designed in the manner of a parallelogram and which can be pivoted about a fixed pivot point 53 via a fixed lever arm 51, attacked by the piston rod 52 of the movement cylinder 5.
  • the squeegee 2 places most of the ink lying in area A back on the screen, namely from ink 17 stowed in area A, and guides it in the direction of arrow B, as shown in FIG Entire sieve up to the jammed ink 7 in area B.
  • This return takes place with the stencil sieve 40 not pushed through, which is also shown in FIG. 5. It is not possible to pressurize the screen when it is returned, since no color should get onto the web 6.
  • the respective printed sections are designated 8 in the drawings. The web will be after him Rietem printing operation of the continuously into corresponding R apportabterrorismen over the work table 9 each preferred or were bow in the print range set.
  • each squeegee is assigned a corresponding movement cylinder.
  • These motion cylinders work in the same rhythm as in the embodiment shown with a parallelogram.
  • the parallelogram arrangement is cheaper to manufacture and less prone to failure.
  • the post doctor blade 3 again lies in any vertical guide 133 and its height can be adjusted by means of a vertically operating movement mechanism, for example a movement cylinder 30.
  • color is not to be understood as restrictive, other application media can also be applied, for example a gloss or sugar liquefied by temperature, etc.
  • the web can consist of a wide variety of materials, e.g. Foils, paper, coated paper, textiles, metal, plastic, wood or the like. in web or piece form.
  • the web 6 can also be replaced by flat products which are guided one after the other under the screen printing stencil 4.
  • the idea is not limited to parallelogram-like movement rods of the main doctor blade and, if applicable, the pre-doctor blade.
  • the advantage of the pivot linkage 50 shown in the form of a parallelogram lies in the simple design. Six pivot points, each lying in pairs, enable the vertical guidance of all three squeegees, with the fixed points being somewhat off-center and all pairs of pivot points being at approximately the same distance from one another.
  • the fixed points 53 and 59 lie below the point of application of the movement device, preferably of the movement cylinder 5, which thus does not act on the articulated parallelogram or the pivot linkage 50 in the center but rather off-center.
