Abstract: A device for continuous treatment of sheet material or the the like includes a permeable drum for wet or dry treatment of textile material, paper or other permeably materials of a certain width having a normal perforated sheet metal drum jacket, upon which sheet metal strips extending longitudinally over the length of the drum are welded at a spacing from one another. The sheet metal strips improve the uniform ventilation of the material lying externally on the a screen mesh covering on the edges of the sheet metal strips and in addition increase the resistance of the drum to bulging.

Abstract: A permeable sheet-metal drum for the wet or dry treatment of textile material, paper or other permeable material of a certain width comprises a normal perforated sheet-metal drum body, on which, along the length of the drum body, projecting sheet-metal strips are attached at a distance from one another. The attachment is achieved by means of bolts or rivets which are inserted into a transverse flange of each metal strip which is perforated like the perforations of the drum and extends perpendicular to each of the sheet-metal strips. The sheet-metal strips increase the drum's resistance to denting and improve the uniform ventilation of the textile or like material lying externally on the edges of the sheet-metal strips on a screen mesh covering.

Abstract: A permeable drum for wet or dry treatment of textile material, paper or such permeable materials of a certain width comprises narrow sheet metal strips or narrow webs. The sheet metal strips extend in an axially parallel direction. Connector members between the sheet metal strips are aligned in the peripheral direction. The connector members, also serving as spacers, are of a one-piece design and connect to adjacent sheet metal strips. Secure connection of the spacers to the sheet metal strips is effected by screws. Radially inward beneath the inner edges of the strips is a sheet metal jacket, provided with apertures, having its axis arranged in parallel to a longitudinal axis of the permeable drum. This additional sheet metal jacket causes a certain dynamic pressure of the air flowing through the permeable drum, so that the treatment result is rendered more uniform. Furthermore, the precision of rotation of the permeable drum construction is increased.

Abstract: Textile webs that are to be dyed, printed, or otherwise finished must be fed to such a treatment process in a clean condition. For continuous cleaning without large apparatus and without environmental impact, the pile of the textile web is saturated with a liquid containing washing-active substances and compounds which are caused to foam under the effects of heat especially under steam. After steaming, the foam that is produced in the steam for cleaning is vacuumed away with the contaminants it contains.

Abstract: Only one of the two bobbins located side by side is wound at a time. When one bobbin is full, a thread guide must switch the thread to the adjacent empty bobbin. In order to keep the thread wound up on the full bobbin from unwinding, it is held by a pressure applying element such as a brush, against the immediately adjacent bobbin flanges until the loop between the bobbins is cut by a cutter.

Abstract: The process serves essentially for the thermal bonding of lightweight nonwovens. For this purpose, the nonwoven is heated up by means of air penetration on a sieve drum of a flow dryer to a high percentage of the bonding temperature, and immediately thereafter is embossed with internally heated rolls in the squeeze roll nip of a calender. The apparatus provided for conducting the process consists of a sieve drum device wherein the embossing calender is arranged.

Abstract: A lightweight container for storing synthetic fibers, liquids granular materials and the like above the level of the floor has a bottom wall and a plurality of upright side walls joined together and attached to the bottom wall. Each of the side walls is formed of sheet metal and is provided with horizontally arranged profiled portions extending in parallel to the bottom wall. In addition, the side walls have identical profiled portions which are spaced from the bottom wall in a corresponding arrangement so that the profiled portions mate or match around the periphery of the container.

Abstract: 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 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 continuous method for shrinkproofing tubular fabric, especially knitted and the like goods, is effected so that the fabric is spread when wet, then compressed lengthwise and then dried in a shrinkproof manner. This method provides for overstretching the fabric more than 130%, preferably even 160%, widthwise, overfeeding the fabric uniformly lengthwise while stretching and spreading the fabric, and immediately thereafter, in a relaxing fashion, drying the fabric continuously and in finished form with brief alternating movements under the influence of heat. During this heat treatment, the shrinkage potential produced is completely eliminated, with the meshes of the fabric moving into a stable position which no longer results in a change during domestic washing or tumble drying. It is important for the economics of the method for the fabric first to be pre-dried to about 20%, and then to be treated as described.

Abstract: An apparatus consisting of a stuffer box crimping device of a conventional type with a cooling device immediately following thereafter and designed as a sieve drum under a suction draft. The dense crimped parcel, conducted to the sieve drum surface from the crimping chamber optionally by way of a chute is seized by the cooling air, thereupon cooled, and continuously transported. The thus set crimped structure can then be deposited without problems onto an endless belt arranged at a spacing therefrom.

Abstract: According to the disclosed process, an endless fibrous material to be cut is wound in spiral form onto a rotatable cutter roll having radially outwardly oriented knives. A cutting force acts from the outside of the cutter roll radially inwardly, by way of a pressure roller contacting the wound material, for cutting, for example, synthetic fibers. In the process, at least two cutting forces are effective against the axis of the cutter roll, these forces being directed against each other. In the apparatus for conducting the process, two pressure rollers are articulated to each other by way of a double rocket arm. Consequently, the optimum cutting level, which will be different in individual cases, is automatically set. The effective cutting force for each roller is of equal strength.

Abstract: A cutting apparatus consists of two cutter cages arranged in direct superposition, with radially outwardly oriented cutters onto which a textile material to be cut is wound in spiral shape and is cut by a pressure roller effective from the outside radially inwardly. The two cutter cages are constituted by cutter supporting disks attached to a spoked wheel; these disks carry cutters which simultaneously equip the upper and lower cutter cages. By using such an apparatus, it is possible to cut simultaneously two continuous strands with only a single device. It is also possible to arrange more than only two cutter cages in superposition at one apparatus.
