Abstract: A highly permeable drum for the wet or dry treatment of textile material, paper or other permeable materials of a certain width has an outer shell comprising narrow sheet metal strips and narrow webs, the extension in width of which is oriented in the radial direction. The sheet metal strips extend axially parallel. According to the further development of this basic structure, the sheet metal strips each consist of at least two strips of half thickness arranged proximate to each other. The juxtaposed sheet metal strips are arranged radially offset with respect to one another so that, at an outer periphery, only half of the total thickness of a sheet metal strip is provided, which arrangement substantially increases the air permeability of the drum.

Abstract: A fiber baling press consists of a rugged machine frame with a press ram in most cases movable from the top toward the bottom, a press box being movable underneath the ram. The press box consists of a press box casing which should be closed all around. This press box rests on a press box bottom plate which, in this case, for the pressing step, is simultaneously the lower press platen. The press ram as well as, in particular, the press box bottom plate are to be fashioned in the manner of a trough in order to impart to a piece of packaging material for the upper and lower sides of the bale of fiber a preliminary orientation directed toward the bale, after the press box casing has been pulled off the bale. A special advantage resides in making the bottom plate have a trough-like opening of the press box casing so that overflowing of the compacted fiber material over the four lateral flanges of the trough is avoided after withdrawing the press box casing. The piece of packaging material, e.g.

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.

Abstract: The permeable drum for the wet or dry treatment of textile material, paper, or other permeable materials of a certain width consists solely of narrow sheet metal strips or narrow webs. The sheet metal strips extend axially parallel, their extension in width being oriented in the radial direction. The webs are oriented in the peripheral direction and form parts of the connecting elements between the sheet metal strips, these connecting elements carrying the screen-type cover. The connecting elements, also serving as spacers, are formed of one piece and connect two neighboring sheet metal strips. Connection of the spacers with the sheet metal strips is achieved by headless screws. The proximate ends of the two screws succeeding each other in the peripheral direction are threaded into a nut which latter, in turn, can be encompassed by a fitting connecting element.

Abstract: A process for the transportation and subsequent final compression of, for example, synthetic fiber material from rough filling presses to a central press utilizes thin-walled filling bins for the initial precompression. In the rough presses, the fiber material is deposited into the thin-walled filling bins, the filling bins are then transported to the central press, transferred at that location one after the other into the compressing position of the central press, thereafter an additional compression bin is placed over the filling bin in such a way that the walls of the filling bin are in close contact with the inner surface of the walls of the compression bin, and finally the final compression step is performed. With a final compacting pressure being maintained unchanged, the filling bin as well as the walls of the compression bin are pulled off in the upward direction in order to make it possible to package and reinforce the finished bale.

Abstract: A device for wrapping a bale or the like with a wire or band held together by a tubular seal comprises an arrangement of units wherein wire is pushed through a metal tube held in readiness, then looped around the bale, and the free end of the wire is again moved through the metal tube. After the wire has been passed twice through feeding of the metal tube held in readiness; the wire is arrested by a limit switch; the portion of the wire end projecting out of the crimping jaws is bent around the metal tube; and tightening around the band is completed. Then the seal is produced by moving the crimping jaws toward each other and simultaneously severing the band from a supply coil. The wrapping operation takes place automatically by a holding device which holds the respectively next needed metal tube into the path of movement of the wire to be extended around the bale.

Abstract: A predrying tower serves for heat-treating a vertically conducted length of material. In addition to infrared heating rods arranged on each side of the length of material and over the treatment height of the drying tower, respectively one air supply box is arranged bilaterally of the length of material. The air supply box extends over the height and width of the drying tower, with air slots oriented to direct air toward the length of material. In order to obtain a circulating air system, the air is exhausted above the treatment zone over the width of the length of material and conducted to a fan arranged at the end face of the drying tower, this fan blowing the treatment air downwardly in an air recycle chamber arranged likewise at the end face of the drying tower. An air ramming or air collecting chamber is arranged on the underside of the drying tower over the operating width, wherein the accelerated air is laterally introduced and exits upwardly via a heating device into the air conducting box.

Abstract: A treatment apparatus for a textile material e.g. a wet tow, has a machine with guide rolls arranged in two rows for the meander-like guidance of the endless textile material. In order to obtain uniform material tension at each of the, for example, top guide rolls, these are not only electrically driven individually but also are subjected to a specific torque, determined by measuring the actual longitudinal tension in the length of material at, for example, the first and last guide rolls, by electronic comparison of the measured data, and by utilization of the positive or negative measuring result for controlling the torque of the incorrectly turning guide roll.

Abstract: A process for washing textile material wherein a non-foamed washing liquor, combined with a foam-producing chemical, is applied to a continuously fed textile material, the foam is produced on the textile material by effecting alternating compression and pressure relief of the textile surface while simultaneously loosening the dirt, and finally the foam, and thus the dirt dissolved in and taken up by the foam, is removed by suction.

Abstract: In an apparatus for the continuous washing of a length of textile material, the textile material runs over several guide rolls, at least one of which is arranged below the liquid level in the washing vessel. In order to be able to skip a washing device, in a continuous plant, so that the length of material does not enter the liquid and causes contamination therein, for example, the invention provides to mount the guide element to be movable out of the vessel. Therefore, the length of material still passes around all of the guide rolls of the washing device, but in this case outside of the liquid charged into the vessel.

Abstract: The invention relates to a process and apparatus for wrapping square bales, especially fiber bales, with the aid of strip-shaped baling material, preferably baling wire. It is known to compress fibers, after having been manufactured as raw material, into fiber bales and to hold the latter together with the aid of baling wire. In this process, several baling wires are placed in individual turns around the bale and joined at their ends. This type of wrapping is complicated and is to be simplified.The basic aspect of the invention resides in that the baling wire is placed continuously around the bale and that the wire turns extend, on at least two mutually opposed bale sides, in parallel to one another as well as in parallel to bale edges.
