  • Patent number: 8782861
    Abstract: The invention relates to an apparatus for compacting a material web made of fibers and/or filaments, comprising a first revolving endless belt which carries the material web and is tensioned around guide rollers, and a second endless belt which is tensioned around guide rollers and revolves counter to the first belt at the same speed, wherein the first and second endless belts form a conical compacting region in a first region in the conveying direction of the material web and run at an angle with respect to each other, whereby the material web located between the belts is increasingly pressed, wherein subsequent to the first region a first nozzle beam is disposed for a first fluid application onto the material web still located between the two endless belts, wherein the two belts in this region of the first fluid application are in each case guided to run in a tensioned manner in a straight direction.

  • Patent number: 8418330
    Abstract: The invention relates to a water bar comprising nozzle parts for a suction chamber to apply jets to fabrics, knitted fabric webs, or nonwoven fabrics copoosed of staple fibers, endless filaments, or cellulose fibers, also in several layers, or mixtures thereof, and a suction area which is located on the bottom side of the suction chamber and is used for sucking off spraying water. The aim of the invention is to largely prevent spraying water or spraying mist in the region of the water jet that is discharged from the water jet beam. Said aim is achieved by assigning an air supplying device to the water bar and/or the suction chamber, said air supplying device being provided with at least one outlet which is located in the region of the water bar and extends to the region of the nozzle ports of the water bar.

  • Patent number: 8220120
    Abstract: A fiber laminate is made by providing a core layer of absorptive fiber material between two outer carrier layers to form a three-layer laminate. This three-layer laminate is then directly juxtaposed with a rigid template formed with an array of throughgoing holes separated by webs. Water jets are then directed at the three-layer laminate juxtaposed with the template to drive the fibers of the core layer out from between the carrier layers at the webs and to hydroentangle the outer layers directly with each other at the webs while leaving the core layer generally intact between the webs at the holes.

  • Patent number: 8082638
    Abstract: The invention relates to an apparatus for producing textiles, nonwoven substances, spun-bonded fabrics or paper materials (5) with the aid of at least one screen drum (1) having openings (4) for transporting away the fluid (6) which is output from a water bar (7) and having numerous outwardly directed elevations (3) which are situated on the outside of the screen drum (1) for the perforation of the nonwoven (5). The invention is based on the object of providing an apparatus which makes it possible, during the water conversion and at the same time as the perforation, also to make patterns in the nonwoven without influencing the strengthening substantially in the process. The object has been achieved in that one or a plurality of regions (8) on the outer side of the screen drum (1) does/do not have any elevations (3) but only openings (4).

  • Publication number: 20110277284
    Abstract: The invention relates to a method for producing a wadding product, in particular for producing wadding pads for cosmetic purposes, comprising the following steps: preparing a preliminary non-woven mat which is made at least predominantly of cotton fibers, compacting said preliminary non-woven mat by using a plurality of hot high-pressure gas jets. For the apparatus it is provided that the device for compacting (2, 12?, 14, 15, 15?, 16, 16?) the preliminary non-woven mat (7) comprises a device for subjecting the preliminary non-woven mat (7) to hot gas at a high pressure.

  • Patent number: 7694539
    Abstract: A suction apparatus for a water beam that directs a liquid jet at a passing a fabric web workpiece has a suction chamber extending transversely adjacent the jet and having a perforated lower wall sloping downward away from an upper region close to the water beam and a lower region remote therefrom. Air is withdrawn from inside the chamber to aspirate spray from adjacent the jet through the perforated lower wall.

  • Publication number: 20100015875
    Abstract: The invention relates to a method for the production of a one-layered or multilayered nonwoven fabric, a machine for the production of such a nonwoven fabric, and a correspondingly produced nonwoven fabric. The task of improving such a method and a production apparatus underlies the invention to the effect that projecting loops and fibrils no longer stick out, and thus individual filaments can be prevented from pulling out during the use of the nonwoven fabric. According to the invention, this is achieved in that the nonwoven fabric is smoothed after water needling by the use of a calendar. The machine according to the invention is characterized by the fact that the machine has a spun bonded fabric, at least one subsequent needling device, a dryer connected thereto, and thereafter at least one calendar.
