| 20110078883 | SUCTION CHAMBER FOR A WATER BAR USED FOR APPLYING JETS TO FABRICS - 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 composed 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. | 04-07-2011 |
| 20100015875 | METHOD AND DEVICE FOR THE PRODUCTION OF A ONE-LAYERED OR MULTILAYERED NONWOVEN FABRIC - 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. | 01-21-2010 |
| 20080307619 | Device for Hydrodynamic Intertwining of Fibers in a Fiber Web - A device is known in which the bulky felt arriving on the top side of an endless belt for water felting is compacted between a felting drum and the belt and at the same time it is wetted by a first water curtain from a nozzle beam, whose water jets first pass through the endless belt and then the fiber web and finally the felting drum. Now, according to the invention, the unconsolidated felt is held against the bottom of an endless belt by means of induced suction and transported, and it is brought up tangentially to a needle felting drum, arranged beneath the endless belt. In this way, the handover of the fiber web from the endless belt to the needle felting drum is accomplished under the influence of gravity. | 12-18-2008 |
| 20080220161 | METHOD OF AND APPARATUS FOR MAKING A SPUNBOND - A spunbond web is made by extruding a multiplicity of hot thermoplastic filaments, passing the filaments along an upstream stretch of a path, cooling and stretching the filaments as they move along the upstream stretch of the path, and depositing the cooled and stretched filaments at a downstream end of the upstream stretch on a foraminous belt such that the filaments form a mat thereon. The belt is continuously displaced the belt so as to move the mat downstream along a downstream leg of the path. The mat on the belt, then consolidated with a high-pressure water-jet treatment, and further processed. | 09-11-2008 |
