Embodiment Construction

[0024] In the aforementioned EP-A-0 841 424, in figure 1 describes a device in which the textile to be supplied with water jets is guided between two consecutive screens advancing conically toward each other, and whereby the water jets first have to penetrate said one screen in order to be needled. prick. Usually the textile is placed directly on the drum, as in EP-A-1 001 064 figure 2 As shown, and the nozzle bar is arranged directly on the textile with the sprayed water jet. The water-permeable roller according to the structure of the present invention is applicable to the above-mentioned two embodiments.

[0025] Screen drum 1 with perforations (perforations 2 in figure 2 shown in ) with its peripheral surface as a component that carries and conveys textiles forward. The perforations in the circumferential surface serve to discharge the water impinging the water jet radially, while the interior of the drum acts as a suction device. In order to be able to act evenly o...

Abstract

The invention relates to a previously known water-permeable drum for hydrodynamically needling webs of textile materials such as nonwovens, tissue, cloth, knitted fabrics, or similar in order to reinforce and structure said textile materials and / or refine the surface thereof. Said intrinsically stable drum is provided with apertures and a tubular sieve-type cloth or knitted fabric which is made ofmetal wires, is pulled across the outer circumference thereof, and is fixed to the face of the drum. In order to prevent creases from forming across the area of the sieve-type cloth when the drum isused according to the specifications, the sieve-type cloth or knitted fabric is provided with a coating that stabilizes the intersections of the wires. Said coating should be a galvanically applied coating, e.g. a nickel plating.

Description

technical field [0001] The invention relates to a water-permeable cylinder for the hydrodynamic needling of textile endless fabrics (textile Warenbahnen) such as non-woven fabrics, tissue paper, braids, knitted fabrics, etc., in order to achieve said endless For strengthening and / or surface quality improvement and structuring of fabrics, the drum consists of an open, inherently stable drum, on the outer circumference of which at least one hose-shaped screen weave made of wire threads is fitted (Siebgewebe) or screen knitted fabric (Siebgewirke) and fix the fabric at the end side on the drum. [0002] The invention also relates to a method for producing a water-permeable roller. Background technique [0003] A drum of this type is known from GBM 1 886 883 in the field of through-flow drying technology. The advantage of this construction is that since the textile to be treated does not lie against the perforated cylinder, this would lead to an uneven flow through of the endl...
