Definitions

  • the invention relates to a device for applying media to flat structures by means of an application device, the application device being assigned a limited space which receives the application medium and extends over the working width, and a feed device for the application medium is provided.
  • the present invention relates in particular to the application of liquid, pasty or viscous media to surface products, preferably to webs, e.g. Textile goods or goods made of fibrous material, carpets with pile, paper, cardboard and the like, whereby chemicals, finishing or washing liquors etc. also colors, color pastes and the like. can be applied, preferably in foamed form.
  • webs e.g. Textile goods or goods made of fibrous material, carpets with pile, paper, cardboard and the like, whereby chemicals, finishing or washing liquors etc. also colors, color pastes and the like.
  • the storage of the foam plays an important role in relation to the relatively large consumption. It must be ensured that the foam supplied first is also consumed first, since foam has the property of causing the bubbles to burst, so that a liquefaction effect occurs which can be disadvantageous if it occurs too early.
  • the present invention is therefore based on the object to provide a device by which it is ensured that the inflow of the medium corresponds exactly to the amount consumed, without excessively high flow speeds occurring or the material to be applied not being transported uniformly to the application level.
  • stockpiling plays a role, which ensures that material is always available.
  • the constant inflow over an entire working range is important, or both.
  • the invention thus consists in that the like or above a sieve. arranged, limited space has a filling area with a feed device for the preferably foamed application medium j and a feed channel to the application level or to the application device, the gap width of which can be selected.
  • the arrangement of a filling area above a feed channel ensures that the feed channel is constantly filled with the medium, evenly and. consequently a sufficient amount of medium, namely freshly supplied medium, is constantly available at the order level.
  • a wall part of the limited space above a sieve or the like adapts in its shape to the application device or adapts approximately and runs parallel or essentially parallel to it, so that a feed channel is present, the gap width of which remains the same over the height of the inlet.
  • This design creates a feed channel above the sieve, in which the application device, e.g. a squeegee, squeegee or the like. lies and in which on the other hand the wall part forms one of the channel walls.
  • the channel is of course closed at the ends.
  • a wall can also simply be provided as the application device, so that the device works as a slot doctor.
  • a sieve or a sieve-shaped intermediate carrier for example also a sieve template, a band template which is guided over rollers, or a round template, a sieve cylinder or the like.
  • This sieve can be used as a perforated sheet, as a latticework, network, wire mesh, as a sieve drum or the like. be trained. It can stand still or, if necessary, be dragged along with the goods or be arranged separately driven.
  • stencils are also envisaged that can apply the liquor or the medium or the foamed medium in a pattern or plain, that is to say in areas, preferably also rotating sieves or stencils.
  • a network made of plastic or synthetic fibers, a wire mesh, etc. can also be placed on the screen.
  • the screens or screen-like intermediate supports cause the bubbles of the foam to burst, thus enabling a liquor accumulation in the area of the screen and the screen-like intermediate support or on its surface and thus enable a perfect order on the goods.
  • the application device which can be designed like a squeegee and / or a suction box, would have to support the transport of the medium or the foam through the sieve. In the latter case, the applicator will make a reciprocating movement, for example, on the flat planar screen template to the A uftragsmedium eg foam or the like through the stencil onto the web. bring to.
  • chalk can be foamed and on paper, a fleece and the like. to be brought.
  • the plastic can also be applied in such a way that it is embedded in the paper, especially if it is absorbent.
  • gloss materials in particular foams provided with gloss material and the like. applied or foams that contain other chemicals to achieve a pattern effect.
  • the stencils can also be colored if they are used evenly without a pattern.
  • a sample order can also be made.
  • screen printing machines a number of printing units are often arranged one behind the other, which apply different colors, which is also possible with the subject of the invention.
  • any flat goods e.g. dyed, finished, coated or washed.
  • the application medium preferably foam, which flows into the application level in the supply area, which can also be referred to as a channel, the gap width of which can be selected.
  • the gap can also be adjustable.
  • the application medium preferably foam
  • the substrate is adequately absorbed with the liquor, namely the application medium, so that, for example, Florware is soaked into the ground or penetrated by the medium, for example, is dyed, washed or printed, while on the other hand in the case of smooth goods, for example when dyeing or printing textiles with a relatively small percentage of openings in the stencil, the feed area must be set relatively narrow in its gap width.
  • the device according to the invention for applying media to flat products initially consists of a machine frame 1 with at least one application unit 10, which works with a screen, for example a screen belt 2. It can be a mesh belt, andschablone a B to a screen cylinder, a circular rotating mask, be a flat planar template or any sieve, whereby when using templates patterned these or unpatterned can be used.
  • An application device 3, possibly a doctor blade and / or a suction box 30, is located on or in the screen 2, the application device 3, 30 being assigned a limited space 4 which receives the application medium and extends over the working width.
  • this limited space has an upper filling area 40 and a narrower feed channel 41.

  • the side bearing heads can also be connected to one another by further cross members.
  • the upper filling area 40 is connected to a fastening strip 140, so that the lower part 142 of the front wall 42 can be fixed in an adjustable manner thereon.
  • the side walls 47 can be designed like a plate.
  • the rear wall 43 is pulled down to the lower run of the screen belt 2 and even forms the doctor-like application device 3 with its lower end, or a strip doctor is attached to it.
  • the front wall 42 and its lower part 142 are similar to those in FIG. 1, but the application device is designed as a doctor blade, on the holder 33 of which the rear wall 43 is built.
  • the narrowed supply channel 41 can be adjusted in its gap a, which is indicated in FIG. 3.
  • the gap setting can be changed by pivoting, in that the squeegee as application device 3 at a different angle to the un lower strand of the sieve belt is set.
