Abstract: A screen drum design is known whose drum jacket consists of sheet metal strips running axially and whose width extends in the radial direction. These sheet metal strips must be permanently connected with the endwise bottoms to produce the drum jacket. According to the invention, this connection is made movable. For this purpose, an articulated ring (32) is used that consists of a number of connecting arms (13) mounted pivotably, said arms being connected with articulation at their free ends either with sheet metal strip structure (13, 14) or with bottoms (11, 12) that are located at a distance from the ends of sheet metal strips (13). In this way, movement is always possible between the drum jacket and bottoms (11, 12) to compensate for dimensional changes as a result of temperature fluctuations.

Abstract: The permeable drum for needling tissues, nonwovens, or other permeable materials of a certain width consists of a normally perforated sheet metal drum on which strips that are thin and extend axially over the length of the drum are arranged with small distances between them around the drum. The strips radially support a very thin sheet metal jacket with microfine perforations and produce a uniform flow of liquid through the material that rests externally against the sheet metal jacket. The strips can be joined together for example to form a honeycomb profile and thus uniformly transfer the hydrodynamic load developed during needling to the screen drum.

Abstract: A screen drum design is known whose drum jacket consists of axially extending sheet metal strips whose widths extend in the radial direction. These sheet metal strips must be permanently attached to the end bottoms to produce the drum jacket. According to the invention, this connection is made movable. For this purpose, a connecting element (17) is provided that consists of one or two connecting arms (18, 19) connected with one another so that they are pivotable with respect to one another, said arms being connected, with articulation at their free ends, with either sheet metal strips (13) or a centering ring (29) for the sheet metal strips, or with bottoms (11, 12) that are located at a distance from the ends of sheet metal strips (13) and/or centering ring (29). In this way, movement of the drum jacket relative to bottoms (11, 12) is always possible to compensate for dimensional changes resulting from temperature fluctuations.

Abstract: The nozzle beam on a device for producing liquid streams for stream interlacing of fibers, for example of a fiber web guided along the beam, consists of an upper part that extends over the working width of the fiber web and a lower part fastened thereto in a fluid-tight manner. On the nozzle beam, on its lower part, a nozzle sheet is mounted with the holes for the nozzles in a fluid-tight manner by means of a sealing O-ring. This O-ring can be replaced without disassembling the lower part from the upper part. In order for this to be readily possible, in the nozzle beam, over its entire length and width and opposite the bearing groove for the O-ring of the lower part, in the upper part of the nozzle beam, a repair groove is provided which is dimensioned vertically slightly larger than the thickness of the O-ring. By means of the repair groove, an elongate strip on which a replacement O-ring is mounted can easily be inserted.

Abstract: In dye applicators that operate by the pouring principle, it is known to store the liquid flowing over an overflow barrier in a liquid supply chamber located in front of it. To produce a dye applicator that can be adjusted to the desired working width, this liquid supply chamber is divided several times by a limiting wall and a liquid supply bore is associated with each of the liquid supply chambers thus formed. The liquid supplied through hoses to the individual supply chambers is distributed stepwise in such fashion that the respective supply openings are connected at both ends in the direction of the working width with first branch lines of the same length, at whose respective ends intermediate outflow openings are provided, to which second branch lines are connected in the same fashion on both sides in the direction of the working width, with said lines being shorter by half of the first branch lines and having a reduced cross section, with the outflow openings provided at the ends for example.

Abstract: A device for hydrodynamic entanglement operates to compact the fibers of a fiber web made of natural and/or manmade fibers. The device includes a first endless belt supporting the fiber web, the first endless belt being guided under tension and stretched between at least two rolls, including a reversing roll, and a second endless belt likewise stretched between at least two rolls, the second endless belt being located opposite the first endless belt and traveling in the same direction as the first endless belt, a tight side of the second endless belt being located opposite a tight side of the first endless belt. The second endless belt is driven to turn in the same direction as the first endless belt. The tight sides of the first and second endless belts are directed conically toward one another along their lengths, so that the fiber web lying on the tight side of the first endless belt is increasingly compressed between the advancing first and second endless belts.

Abstract: Fiber fleeces made entirely of pure artificial (polymeric) fibers or mixed with natural fibers have to be solidified after formation by carding, or laying only in the case of filament fleeces. In the fleece according to the invention, which is particularly bulky and thus needs to be solidified, neither lower-melting binding fibers nor chemical binding agents are used. Also, the mechanical needling process which uses needles is eliminated because this reduces the bulk too severely. The desired bulk is retained by producing solidification by a single water needling process (when performed on one side), with the desired water pressure being no higher than 60 bars, preferably 20-30 bars.

Abstract: In dye applicators that operate by the pouring principle, it is known to hold back liquid flowing over an overflow weir in a liquid supply chamber located upstream of the weir. To achieve a dye applicator that can be adjusted to a desired working width, this liquid supply chamber is subdivided several times by limiting walls, and a liquid inflow bore is associated with each of the partial liquid supply chambers thus formed. The flanks of the liquid supply chambers delimited by a parallel dam and opposite dam are designed to diverge and to create a plurality of separate liquid supply chambers that expands toward the overflow weir.

Abstract: To supply a liquid uniformly to a dye applicator, the liquid must be divided in a specific way before the liquid reaches a strip of the applicator. This is accomplished with a hollow plate which has a large number of tube fittings on its outer circumference for the through flow of precisely constant amounts of liquid. These fittings, for treating different working widths of the applicator, must be provided at least partially with valves to close them. In order to keep the distributing plate small in diameter and simultaneously to be able to close one through flow channel or another, special channels are provided in the plate that are easy to close and can be controlled exactly with respect to liquid flow.

Abstract: In a washing method, a web of textile goods is wetted with a washing-active liquid and the liquid is caused to foam by steam which is blown at high pressure into a back side of the web of goods with a pile on the front side. The steam is discharged from a nozzle slot that extends transversely across the web of goods. The nozzle directs the steam against the web and through it. The foam which then suddenly forms is then drawn off by a vacuum or suction together with the liquid still in the pile from the pile side of the web.

Abstract: Multiple needling with web guidance on alternate sides is achieved. Either an endless belt and/or a drum performs a carrying function, the belt or drum being arranged so that the fiber web can be associated meanderwise with the other side of a nozzle beam in each case. Transfer from one transport device or unit to another takes place by constant, positive, and non-stretching support of the fiber web, which is sensitive to being stretched.

Abstract: A device for application of a minimum quantity of fluid to a web of goods of a given width, wherein application takes place by means of an application beam in which the fluid is distributed uniformly over the working width through a plurality of fluid lines that branch in the manner of a tree trunk. The outlet openings of the lines terminate in a slot that is open facing the web, the length of the slot being delimited by two lengthwise edges. These edges press against a pressure roller located on the opposite side, i.e the back of the web. By means of these lengthwise edges, as the web passes though, its nap is compressed twice, once at the beginning of application with a first lengthwise edge, after which the nap stands up again in the slot and is saturated with the fluid, and again at the end of the application, after which the web is finally squeezed against the second lengthwise edge.

Abstract: Fiber fleeces made of synthetic fibers or of natural fibers are compacted after their formation, for example, by carding or by simply being laid down in endless fiber fleeces. In the fleece according to the invention, which is intended to be voluminous yet compact, neither low-melting binding fibers nor chemical binders are used for the purpose. The mechanical needling method, i.e. with needles, cannot be used, however, because the volume is reduced too sharply. The desired volume is retained and the double fleece desired for hygienic products, for example, is achieved by the fleece produced, for example, on a card machine or aerodynamically initially being laid down on a previously compacted fleece, such as spun fleece made of endless fibers for example, as the carrier fleece and then being compacted in a continuous processing method by water needling at a water pressure of at least 100 bars and, preferably 180 bars, and thus being simultaneously joined to the carrier fleece.

Abstract: A jet bar on a device for producing streams of liquid for jet interweaving of the fibers of a fiber web guided along the bar includes an upper part that extends over the operating width of the fiber web and a lower part fastened thereto in a liquid-tight manner. In the upper part and extending over its length, a pressure chamber is located which receives liquid that is under pressure, endwise for example. Parallel thereto, with an intermediate partition, a pressure distribution chamber is provided which is connected with the pressure chamber by throughflow holes for liquid extending through the intermediate partition. A jet sheet with holes for forming jets of liquid is mounted in a liquid-tight fashion on the lower part.

Abstract: A stuffer box crimping unit provided with a crimping chamber and two feed rolls associated with the chamber and located upstream thereof, has pressure disks associated on both sides in side walls of the crimping chamber at the level of the nip between the two feed rolls. These two disks are not only made from a material provided for wear, but also from a separate carrier disk made of appropriate material. The carrier disk is a wear element shaped like a lid and made of the nonferrous metal intended for wear in the direction facing the pressure roll nip. This wear element is readily replaced and there is no need any longer for regrinding the wear surfaces of pressure disks so that the disks can be reused.

Abstract: The position of the exhaust air flap of a through-flow dryer, for example, a screen drum dryer, is adjusted to determine the moisture content of the exhaust air. This is advantageously accomplished as a function of the desired drying temperature of the goods or their moisture content when the good leaves the dryer. Provision is made according to the invention to measure the temperature of the air after passing though the web, at least in the vicinity of the outlet of the dryer, to relate it to the temperature of the ambient air and thus to determine the temperature of the goods and hence their moisture content, since in the residual drying range, the moisture content of the goods is a function of the temperature of the goods. The exhaust air moisture content can then be regulated with this measured value.

Abstract: A method wherein a thin card web which contains meltable synthetic fibers as well as natural fibers is processed into a thicker web of fleece. The synthetic fibers are initially melted to prestrengthen the web. Then the web is saturated with the appropriate fluid finishing agent for making the web flame-resistant and the like and this web can then be readily dried on a screen drum dryer. It is at this point that the web layers are accumulated into a proper fleece in a cross layer unit which transfer the end product to a heat treatment assembly for heating to effect vulcanization, curing or setting of the synthetic fibers.
