Abstract: Laboratory-scale dyeing of samples of lengths of material must correspond to the continuous process conditions as executed in practice in order to obtain comparable dyeing results. For this purpose, the provision is made of joining the sample piece into a tube and of pushing same onto a roll which revolves continuously during dyestuff application as well as during the steaming procedure. For performing this laboratory dyeing-steaming cycle, it is advantageous to arrange the dyeing roll on a rocking lever pivotable from i dyeing position below the dyestuff applicator into a steaming position below a steamer hood. The steamer hood, for steaming purposes, need merely be moved downwards to immerse the dyeing roller in total into the steam atmosphere.

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.

An adjustment unit which is connected to at least one sensing device, which holds, through the adjustment unit, the pressure disk against the end surface of the roller under a pressure force. The sensing device is constructed as an instrument for determining the bending, adjusted on the basis of the pressure force, of a carrier for the pressure disk and the pressure force is adjustable in dependence on the continuously determined bending of the carrier.

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.

A treatment chamber is formed between the sieve drum and one of the container walls and liquid is fed to this treatment chamber from a distributor duct located above the treatment chamber. The distributor duct includes a liquid discharge slot for feeding the liquid to the treatment chamber. A pump is provided for feeding liquid into the distributor duct and the liquid discharge slot is arranged to fed liquid uniformly across the operating width of the sieve drum.

Abstract: An improved process for the continuous dyeing of lengths of textile material that at least partly contain cellulose fibers by the Pad-Steam process wherein the textile material onto which dyestuff has been applied is impregnated with chemical reducing agents including an alkaline solution, is then transported into a steamer for dyestuff-fixation by steaming thereon, is then after-treated by the sequential steps of rinsing with a liquor to remove the reducing agents, oxidizing the dyestuff with a liquor, and soaping and again rinsing the material with a liquor, and then finally drying the material. The improvement in the process comprises effecting the after-treatment steps, at least partially, by forcing the appropriate liquors through the material, especially on the perforated surface of a suction drum.

Abstract: An apparatus for the wet treatment of fibrous materials includes a container filled with a treatment liquid, a liquid-permeable support for the material arranged with a supporting surface at least partially underneath a first liquid level within the container, and means for providing a second liquid level extending uniformly along the entire length of the immersed supporting surface and underneath said supporting surface of the support.

Abstract: A process for the continuous dyeing or printing of lengths of textile material, such as carpet panels having a portion which consists of shrinkable fibers that are set prior to the application of dyes or printing inks includes the step of forcing a hot liquid medium through the length of textile material.
