Abstract:
Devices for water needling consists of a nozzle beam that is located transversely above the fiber web to be compacted. The water emerges in fine streams at high pressure from a plurality of nozzles and tangles the fibers to compact them, to change the surface, and to braid the fibers of the tissue or the like. Since this web must be guided past the nozzle beam, a lengthwise striping develops. In order to influence this advantageously, according to the invention the nozzle beam is caused by a vibrator to perform quite specific transverse oscillations. The resultant zigzag movement, with the generated groove depressions being located with their edges adjacent, produces a completely smooth surface without significant plastic elevations.
Abstract:
The invention describes a device for through-flow continuous processing of textiles, nonwovens, or paper in web form with a gaseous processing medium circulated in the device. The material rests on the outside of a permeable drum subjected to suction, said drum having bottoms on the ends, namely a sieve-type or perforated covering that rests on the drum structure. For this purpose, sheet metal strips firmly connected with the bottoms extend from one bottom to the other between the bottoms of the drum, with the widths of the strips extending in the radial direction. These sheet metal strips are secured over their entire radially aligned height firmly but releasably to the corresponding bottoms by means of the clamping structure.
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:
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:
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:
A device for applying a laminar flowing liquid film of considerable width, the film being uniformly thin over the working width, to a continuously advanced web of goods includes a liquid distribution device supplied with liquid fed by a pump and provided with a plurality of liquid distribution chambers and an associated guide surface from which the liquid film flows onto the web of goods. The liquid distribution chamber is connected by a supply line with the pump and the guide surface extend over a working width greater than the cross section the of supply line. Each liquid distribution chamber extend only over an exactly defined working width which is narrow by comparison with the width of the wider web of goods, and each chamber is connected with only one liquid supply line.
Abstract:
In the sieve drum device, a screen cover is not arranged, as customary, horizontally with sieve drums located, for example, in side-by-side relationship, but rather concentrically surrounds the respective sieve drum in the region covered by the material. In order to facilitate cleaning of the screen cover, the cover is swingable swung about a joint arranged on an axis in parallel to the sieve drum axis.
Abstract:
The piece of packaging material (e.g. a sheet or plastic placed on the topside of the fiber material to be compacted exhibits marginal zones projecting all around, which must be detached from the press ram after the compressing step and must be placed against the bale. For the automatic detachment of the sheet from the press ram, leaf springs are fastened for this purpose at the side faces of the press ram and urge, after withdrawal of the press box casing, these marginal zones away from the press ram. Subsequently, the press box casing located there above again travels downwardly to the bale, namely only up to the top rim of the latter, during which step the marginal zones of the sheet projecting from the bale in the upward direction are uniformly brought into contact with the bale.
