Definitions

  • the invention relates to a device for the production of textiles, nonwovens, spunbonded nonwovens, paper materials and / or perforated films with at least one screen drum with openings for the removal of the liquid discharged from a water bar and located on the outside of the screen drum numerous outwardly directed elevations for the perforation of the web, one or more areas on the outside of the screen drum have no elevations but only openings.
  • the US 5115544 A shows only a method in which the patterns are pressed by means of elevations in the fleece. However, the elevations should not form the imprint in the fleece in the subject of the application, but merely surround the pattern to be formed on the sieve drum.
  • a process for producing a nonwoven fabric is also known (US Pat. DE69224769 ), in which a carrier tape (5) is used, at the forming Side a plurality of approaches (6, 6 ') is mounted.
  • the mentioned approaches (6, 6 ') have a larger and a smaller size. These are made of thermoplastic resin and welded to said forming sides of the tape.
  • a quantity of fiber (2) is applied to said band (5) provided with irregular patterns formed by said lugs (6, 61). Water or hot air is applied under high pressure to the stated amount of fiber in order to press them and to entangle the fibers. Subsequently, said amount of fiber (2) is pressed onto said lugs so as to form patterns on the web.
  • the invention has for its object to provide a device which makes it possible during the water needling at the same time to introduce perforation and patterns such as animal pictures or plant pictures or other geometrically demarcated figures in the fleece, without significantly affecting the solidification. Furthermore, this gives a closed area in the web with vents instead of openings that are distributed over the entire surface of the web. In the latter case, the strength or stiffness of a nonwoven fabric is not achieved to the desired extent.
  • the advantageous division of the nonwoven surface into areas with and without vents, the strength or rigidity of a nonwoven can be significantly improved, the pattern are designed in particular by vents.
  • the object has been achieved in that the areas which have the elevations and which serve to form a surface pattern in the fleece, such as animals, plants or geometric shapes, are arranged in a corresponding arrangement or grouping on the drum basket and the surface pattern to be formed on the outside surround or restrict the sieve drum.
  • the advantage of this device consists in particular in the fact that the patterns are introduced not only by the targeted perforation by elevations or mandrels, but that the patterns are formed at the points in the fleece to which only drainage holes and no elevations or spikes are.
  • the areas with elevations or mandrels cover a major part of the screen drum surface.
  • the ridges or spikes randomly disposed within their respective areas the greater part of the area of the web is uniformly solidified by the perforations formed in the web.
  • the areas formed as patterns are perforated.
  • the elevations are at least partially distributed irregularly on the outside of the screen drum or at different distances from each other and / or arranged at a uniform distance from each other.
  • At least openings for the passage of liquid discharged from the water bar are provided on the outside of the screening drum in areas in which elevations and / or in the areas in which no elevations are provided.
  • the elevations on the outside of the screen drum have the form of mandrels.
  • mandrels straight lines, wave structures or raster shapes can be generated, with the mandrels after the pattern formation can easily be pulled out of the nonwoven fabric again.
  • the elevations are conically tapering or tapered outward or cylindrical shape towards the outside.
  • elevations have a circular, oval or polygonal or square or oblong cross section.
  • elevations are arranged in the region of a basket drum shell with elevations at a distance between 1.5 mm and 20 mm, preferably 3 mm to 10 mm.
  • the elevations are advantageous for the elevations to cover a region of the drum shell between 20% and 50%, preferably between 25% and 30%.
  • the areas without elevations total make up an area of 1% to 50%, preferably between 20% and 50%, or between 25% and 30% of the total surface of the screening drum.
  • the regions which have elevations and which are used to form surface patterns in the fleece, such as animals, plants or geometric shapes are arranged in a corresponding arrangement or grouping on the sieve drum sheath.
  • the patterns in the web are produced in this embodiment of the invention by areas in the fleece, which are not perforated by the elevations on the basket drum shell.
  • the areas which have no elevations and the areas, the elevations for forming a surface pattern, such as animals, plants or geometric shapes are arranged in a corresponding arrangement or grouping.
  • the areas with elevations or mandrels cover a large part of the screen drum surface, cause in the web the desired solidification of the nonwoven fabric and at the same time contribute to the surface patterning of the nonwoven fabric.
  • the pattern produced in the fleece at least partially or predominantly lie in the plane of the web and the fleece has an at least approximately the same thickness, wherein the perforations introduced in the fleece are distributed so that one or more same or different shaped Illustrate surface patterns in the fleece.
  • the areas of the drum shell without Elevations and the areas with elevations each form a delimited area.
  • the areas of the drum shell are connected without elevations or surround the areas with increases or include.
  • the openings in the basket drum over the entire surface of the basket drum shell are evenly and / or unevenly distributed and have a diameter between 0.1 mm and 3 mm, preferably between 1 mm and 1.5 mm.
  • the areas with elevations or mandrels cover a predominant part of the screen drum surface, cause the desired solidification of the nonwoven fabric in the nonwoven and at the same time contribute to the surface patterning of the nonwoven fabric.
  • a screen drum which consists of a screen drum shell 2, which may consist of a plastic or metal and which is supported by means of support members 11 on a cylindrical or more strongly formed tube 13.
  • the screen drum shell 2 thus forms the surface of the screen drum 1.
  • the screen drum shell 2 has openings, drainage openings or micropores 4, which serve to remove the sprayed from the water bar 7 water of a water jet 6.
  • the tube 13 also serves as a suction tube to suck the sprayed onto the basket drum shell 2 and thus on fleece 5 water again. The removal of the water then takes place via an incorporated into the tube 13 suction slot 12, to which a vacuum is applied.
  • two or more water bars 7 may also be arranged in the region of the screening drum 1.
  • a pipe 13 is provided with correspondingly two or more suction slots 12.
  • the screen drum shell 2 numerous outwardly directed elevations 3, which serve the perforation of the web 5. These elevations or mandrels 3 leave small holes or perforations 14 in the fleece 5 during the hydrodynamic needling, which are substantially sharply demarcated and for this purpose are pressed into an already consolidated or partially consolidated nonwoven fabric 5.
  • the perforations 14 in the fleece approximately correspond to the cross section of the mandrels 3.
  • elevations 3 are arranged in the form of thorns close to each other.
  • the areas 9 with the spikes 3 represent closed or firmly delimited areas.
  • the spacing of the elevations or mandrels 3 relative to one another is uneven.
  • the elevations 3 on the outside of the screen drum 1 or on the screen drum shell 2 are after the in Fig. 3 illustrated embodiment arranged irregularly distributed. However, the elevations may be arranged according to an embodiment not shown in the drawing with a uniform distance from each other.
