Definitions

  • the invention relates to a device for feeding an application medium onto a flat structure, the application medium being placed in front of an application device.
  • Such devices are known per se in stencil printing machines. These devices for supplying an application medium such as paint, color paste, color liquid or the like. are designed differently, depending on whether you want to work with a rotating belt template, with a rotating circular template or with a flat screen template.
  • Rotating stencils generally use ink supply pipes which are guided from one side bearing head to the opposite side bearing head of the stencil or the stencil guides, each ink supply pipe having outflow openings or nozzles which are directed upwards or downwards and are connected on one or both sides to supply hoses, through which the paint is pumped from a storage container into the feed pipe.
  • These known devices work with liquid agents, which spread themselves over the working width.
  • the present invention has for its object to provide a device for supplying a foam provided with an application medium, which places it evenly in front of an application device of any type, so that it from the application device through preferably the screen or a stencil onto the goods can be applied.
  • a uniform template for the application device is to be created, regardless of the width at which the application device works, for example also on a working width of five or more meters, and moreover sufficient of foam provided with liquor must be presented to the application device, since foam is voluminous and during printing or d . large quantities are consumed.
  • the difficulties of the foam application that the foam stays where it is placed, are to be eliminated.
  • the invention consists in that the application medium is supplied in a foamed form and at least one movable outflow device is provided as the feed device, which is connected or can be provided with a drive for its back and forth movement and the foam is preferably placed in an overlying sieve as Storage room serving space.
  • This has the advantage that at least one outflow device constantly runs back and forth in front of any application device and, since it is connected to adjustable and controllable inflow members, the amount of foam placed in the application device can be regulated.
  • the working width is very large and the unit of time , in which an outflow device runs from one side to the other, too large to place enough foam in front of the application device, especially when high Working speeds, for example when working with rotating screens or stencils, it is advantageous to arrange several outflow devices with feed rates that work partially or completely overlapping, so that sufficient material can be presented to the application device, which constantly consumes the dye-containing foam in large quantities which, as mentioned, does not flow as easily as normal fleets.
  • the object of the application is intended to dye, refine, coat or wash essentially flat goods.
  • the object of registration can also be used for "printing" in the sense of sampling.
  • the main component of the foam is liquefied again when it is pressed or sucked through the sieve. Both are done by the application device, which can be similar to a squeegee, or a suction device. The resulting amount of liquid is thus evenly distributed on or in the substrate. This entry or order takes place evenly over the entire work width. Working widths of over five meters are also considered.
  • Stencils can also be used as sieves, they can be patterned or not, they can be designed as simple sieves or sieve cylinders or sieve belts.
  • These sieves or the sieve-like intermediate supports lie on the flat structure and are optionally only perforated sheets, they can be used as a latticework, network, wire mesh, as a sieve drum, template or the like. be trained. The sieves can stand still and, if necessary, be dragged along with the goods or be separately driven. Among other things is, as already mentioned, also thought of stencils, which can be applied to the fleet in a pattern or in plain colors. Rotating screens or templates can also be used. Networks made of plastic or, for example, synthetic fibers, wire mesh, etc. can also be applied.
  • All of these sieves or sieve-like intermediate carriers cause the bubbles of the foam to burst, thus enabling a liquor accumulation in the area of the sieve and the sieve-like intermediate carrier or on the surface thereof, and thus enable a perfect application to the goods.
  • the application device and / or the suction device which support the transport of the foam through the sieve, would have to be moved.
  • Foamable plastic plastic with solvents
  • the plastic can also be applied in such a way that it is embedded in the paper or in the material, particularly if it is absorbent.
  • foam chalk It is also possible to foam chalk and apply it to paper or non-woven fabric or to other goods.
  • a latex coating e.g. on textiles. It is advantageous if the foam structure of the foam is retained as much as possible and the foam is solidified or subsequently polymerized in the usual way.
  • Partial surfaces can also be applied with paints or with plastic resins to a wide variety of fabrics.
  • FIG. 1 corresponds approximately to a printing station design according to DE-PS 2 258 892.
  • the application station 1 of this embodiment works with a screen 2 or a stencil or a screen belt, which is guided over rollers 10, 11 and 12, wherein the rollers 10 and 11 can be driven and the roller 12 can serve as a tensioning roller in a manner known per se.
