Definitions

  • a device of this type is also for the heat treatment of flowing through Textile known from DE-GM 1 886 883.
  • a joist in the scripture proposed a mesh with a coarser wire diameter.
  • This additional Drum assignment has the advantage that that lying on the perforated drum Ventilation can be carried out more evenly than with immediate contact of the goods on the perforated tin drum.
  • the material to be treated lies due to the additional sieve mesh at a greater distance from the drum surface so that there are no dead areas, no flow through the surface of the property Areas result.
  • EP is also 0 223 614 B2.
  • the cover consists of a finely perforated cylindrical sheet metal cover.
  • the drum construction supporting the sheet there consists of a longitudinally perforated cylinder with between the rows of holes arranged, radially projecting, each tapering, axially aligned Ribs. The production of such a drum is very complex and expensive.
  • the invention has for its object a screen drum construction for Form water needles so that an even, finely divided Water permeability of the drum is generated, and at a low cost Manufacture of the drum no risk of changing the cylindrical orientation a thin drum covering. At the same time, it should also be guaranteed be that the discharge of the sprayed liquid due to the suction from the inside of the drum without sucking in false air from the edge areas the sealing lines of the suction device can be carried out
  • a device for the hydrodynamic consolidation of nonwovens, tissue or paper with one liquid treatment agent sprayed against the material from a large number of nozzles, Consists of one assigned to the nozzles, with negative pressure inside if necessary provided permeable sheet metal drum as a rigid support element for the good in needling water, which on its circumference with a liquid-permeable sheet that as a thin sheet with a microfine Perforation is formed, covered, and between the liquid-permeable Sheet and the sheet drum from an unstable stand alone Strips alone to increase the distance between the metal drum and the Sheet metal is provided, the strips each small and constant Distance evenly over the entire circumference of the permeable sheet metal drum are arranged and the permeable sheet metal drum on the radially inside lying edges of the strips and the liquid-permeable sheet on the radially outer edges of the strip directly abuts.
  • a major advantage of the construction of this water needling drum according to the invention is the good one and can also be used over a long period of time constant liquid permeability, even with a drum, which has a cylinder-like smooth surface.
  • the liquid jet coming from the nozzles does not become a spacer or just a little resistance. Due to the dense arrangement the strip remains cylindrical and the thin sheet metal jacket remains however, there is enough space between the strips that it may come out fibers detaching the nonwoven dressing do not clog the drum or only clog it very slowly, thus reduce their permeability. There is no risk of Jamming fibers in a previously used for spacing Wire mesh.
  • the drum is particularly suitable as a support drum when needling water from nonwovens, leaving a smooth surface of the needled fleece through the finely perforated cylinder jacket should.
  • the jacket can also be made of a structure that is particularly structured radially on the outside Sheet exist, depending on the surface of the fleece after water needling should receive.
  • the strips are arranged very close together, e.g. B. with only 3 mm distance.
  • the strips are also very thin, e.g. B. 1 - 2 mm in cross section.
  • the Stripes accordingly have a length of only 4 - 6 mm.
  • the strips are connect with each other. It is appropriate that a number of such strips forms a longitudinal stripe that extends over the entire length of the drum or extends circumferentially around the drum.
  • the longitudinal stripe is then wavy or formed in a zigzag shape so that areas are formed which are adjacent to one another Stripes touch each other. Then there are many on these surfaces to connect the longitudinal strips with each other, such as gluing or welding. This creates a z. B. honeycomb structure with very fine and short stripes.
  • the joist can also consist of strips aligned axially or even formed from alone or in combination with radially extending strips be.
  • the construction is to be selected depending on the application.
  • the endless belt 8 that wraps around the takeover roller 5 ensures also the transport of the needled fleece 2 from the takeover roller 5 to the following roller 5 ', which - also not shown here - nozzle bar 7 are assigned.
  • the takeover roller 5 is liquid-permeable, which is shown in Fig. 1 by the dashed line.
  • the through the Nozzle bars 6 and 7 liquid sprayed onto the fleece is passed through the roller 5, 5 'blown and from the inside also by a suction 9 generated there dissipated.
  • the needling rollers 5, 5 ' are each designed as a sheet drum.
  • she consist of a cylindrical curved forming the supporting structure Sheet 10, which is evenly distributed over the entire surface with a perforation 11 is provided.
  • a microfine perforation is provided radially on the outside over the sheet metal drum 10 Sheet 12 drawn on which the fleece 2 rests when needling. So that Permeability of the fine sheet 12 due to the impermeable webs between the holes of the metal drum 10 is not noticeably obstructed Spacing of the sheet 12 from the sheet drum 10 strips 13, which in Cross section are smaller than 2 mm and axially and radially around the drum 10 extend.
  • the strips 13 are a short distance from z. B. 1 - 10 mm, preferably 2 - 4 mm, arranged so close to each other that each other the sheet metal jacket 12, which is fine in cross section, as a covering between the strips 13 cannot bend.
  • a system for needling a fleece usually consists of several Drums 5, 5 'etc. with alternating loading of the fleece the water jets. Since the drum in the embodiment of FIG. 1 10 is wrapped by the endless belt 8 to bring the fleece up, should the construction with the microfine perforated sheet 12 and the invention Beam 13 z. B. are on the drum 5 ', etc.
  • the stripe structure of the drum 5 'thus consists of the radially aligned Strips 13, the radially aligned height of which can be seen from FIGS. 2-4.
  • the Strips 13 can also have a different cross section. You can join their radially outer circumference is rounded or tapered in order to resist the water jets as little as possible. So there is only the screen-shaped, microfine perforated sheet metal jacket 12 the radially outer edges of the strips 13.
  • the strips 13 lie with its radially inner edge directly on the sheet metal drum 10 on and are next to each other on the Sheet metal drum 10 arranged. So that distance and precise alignment the strip 13 is fixed across the width of the drum, those in Fig.
  • FIGS. 3 and 4 show honeycomb profiles.
  • the webs 13 can but also connected to each other to form a square. This is just a question the production.
  • the stiffeners do not run in the axial direction, but at an angle of less than 90 ° so that there is no line on the tissue appears parallel to the alignment of the nozzle bar 7.
  • the permeability of the covering 12 through the support structure of the Sheet metal drum 10 is not noticeably disabled, also serve in the embodiment 5 for keeping the covering away from the sheet metal drum 10 Sheet metal strips 13, which not only extend radially, but around the sheet metal drum 10 can loop around the drum 10 in the circumferential direction.
  • the Sheet metal strips 13 are so close to each other at a short distance arranged that the sheet metal jacket 12, which is fine in cross section, acts as a covering between can not bend the sheet metal strip 13.
  • the radial ones Stripes are shown on the left in Fig. 5. It makes just as much sense Bleaching strips 13 instead of exactly radial, now spiraling over the entire axial Length to loop around the drum as indicated on the right side of FIG. 5 is.
  • the material of the beam can be made of plastic such as aramid or also Be made of aluminum. In the case of aluminum, it is appropriate to use the profile to chrome-plate.
