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. After the bale has been carried away, the jacket of the filling bin is shifted downwards relatively to the jacket of the compression bin and reunited with the bottom of the filling bin.

The process for rendering wool sliver shrinkproof involves complete wetting of at least one laterally unguided wool sliver with a chlorinating liquor at ambient temperature wherein the liquor is applied to the sliver with a four- to sevenfold excess. The sliver is conducted immediately thereafter through a guide slot, together with the applied excess quantity of liquid; the complete wetting of the fibers of the sliver with the chlorinating liquor is effected in this guide slot by separating the wool sliver from possible air occlusions. Subsequently thereto, the sliver is accompanied by the liquor through a small-volume guide channel, to be squeezed out following the chlorine treatment. The apparatus has a pair of squeeze rolls, the cylinders of which are arranged to be spaced apart to form a guide slot and are rotatably mounted, these squeeze rolls being associated immediately thereabove with spray means to supply the chlorinating liquor necessary for complete wetting.
Abstract:
A method for wrapping a bale or the like with a wire or band held together by a tubular seal is described 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 the metal tube held in readiness; the wire feed is arrested by means of 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 the supply coil. The wrapping operation takes place fully automatically. For this purpose, an apparatus is provided which holds the respectively next needed metal tube exactly into the path of movement of the wire to be extended around the bale.
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:
A baling press for fibrous materials, such as textile fibers, is equipped with a baling box into which a baling ram is movable under hydraulic or pneumatic pressure. The baling box is supported on a base and has hinged walls which are hinged to one another and/or to the base. These hingeable box walls are locked to each other in the box closing position by a piston cylinder locking device in which the piston rod is provided at its free end with a locking member which cooperates with a respective locking element attached to the adjacent wall.
