Definitions

  • WO 02/052083 it is known to store even three-dimensional finite goods such as intermediate or intermediate products between two nonwovens to connect by hydrodynamic needling the superficial webs by entangling the fibers to solidify and thereby enclose the goods.
  • the trapping can be done by a single intermittently controlled nozzles but also by a continuous curtain of water from a nozzle bar, which is partially effective by means of an all-round template. It is also thought to provide the nozzle bar with a nozzle strip which is only partially perforated to bring a pattern in the web.
  • the invention has for its object to find a method by which a single web containing an homogeneous mixture of possibly different fibers, but also alone z. B. may consist of cotton, so solidify that the central region remains voluminous, while the edge regions are fully solidified.
  • the full-surface pre-consolidation - as with the Nähwirkmaschine or with the water needling - can be done in a different machine park with subsequent winding of the now transportable fleece, but more advantageous is a continuous treatment to achieve the finished product in a system with adapted speeds of the individual machines.
  • the solidification of the fleece should therefore only take place at certain points. These locations are along spaced strips in both the transverse and longitudinal directions. When the fleece is subsequently cut along these strips, the result is a continuous, manipulable, finite fleece product whose edges are compacted all around, but whose middle region remains voluminous, as achieved in the pre-consolidation. Thus, fraying of a voluminous finite piece of nonwoven fabric during further treatment can be avoided.
  • the plant for the production of the web consists with respect to the solidification of a stencil drum or a stencil endless belt with spaced slots along the drum or an endless belt for the transverse strips with internally disposed nozzle beam and from a directly associated with the nonwoven further nozzle beam whose nozzle strip spaced apart rows of Has perforations for the longitudinal strips.
  • a nonwoven 1 coming from a carding or similar nonwoven laying machine which can be formed from the most diverse fibers, but here cotton is preferred, is laid on an endless belt 2, which transports the nonwoven through the solidifying system indicated in FIG.
  • the loose non-manipulatable nonwoven fabric is to be solidified over the entire surface in such a way that, while its volume decreases, its maximum retention remains.
  • a full-surface water needling can be used, but remains after solidification, the volume is not so optimal.
  • a stencil drum 4 in the interior of which a water bar 5 extends longitudinally, serves for this purpose.
  • the over the entire length of the water bar 5 against the template effluent water jets 6 are transmitted only along the slots 7 provided here and then meet the web 1 'for full solidification in the region of these slots 7.
  • the longitudinally of the stencil drum 4 respectively adjacent slots 7 produce For this purpose, they are separated in relation to the slot-shaped opening 7 of only a small web 8.
  • the slots can z. B. have a width A of 95 mm, while the web 8 between two slots 7 may have a width B of 5 mm.
  • the longitudinal strip production takes place in the example.
  • a normal water bar 10 is provided, the nozzle strip for generating the water jets 6 'is not perforated over its entire length, but according to FIG. 2 only in sections, so that over the surface of the web longitudinal strips 11 arise.
  • the longitudinal strips 11 are in their arrangement coordinated over the surface of the web to the interruptions of the transverse strips 9 in the region of the webs 8 in the template 4. It is expedient to produce the longitudinal strips 11 on the nonwoven 1 where no consolidation takes place during the stencil treatment.
  • the width C of the longitudinal strips 11 may cover the width B of the interruptions due to the webs 8.
  • the longitudinal strips have a width C of 10 mm, while the width B of the webs is 5 mm.
  • a karoförmige solidification which arises all around a region 12, which is not hit by the water jets.
  • the fleece can now be cut longitudinally and transversely, in the area of full solidification along the strips 9 and 11. This results in quadrilateral nonwoven products as shown in FIG. 4, which are fully solidified at the edges, the central region 12, however, is voluminous , Products of this kind are z. B. needed in the hygiene industry.
