Abstract: A method for producing a spinning box frame for an open-end spinning machine wherein lateral elements (2, 3) of a spinning box frame (1) are connected with interposed bracing elements (4, 5, 6) by means of a welding process which substantially prevents the occurrence of heat distortion tensions. The bracing elements (4, 5, 6) are joined by means of a laser welding process, preferably with a CO.sub.2 laser, squarely on the interior wall (20) of the lateral elements (2, 3). The components (2 to 6) of the spinning box frame (1) are fixed in place in a welding device (26), which permits the exact positioning of the individual components during the laser welding process.

Abstract: A colored yarn is made in an inexpensive manner that allows a wide variety of different colors or hues within the product line, and also allows a wide variety of different effects to be produced including yarns with minimal leather effect, or yarns with a distinct and desired heather effect. A first coarse feeder yarn, e.g. a 1/1 semi worsted yarn, is ring or open end spun with about 2.5 turns per inch. The coarse feeder yarn is dyed, dried, and then cut and opened up into individual fibers about four inches long or less (preferably two inches long or less). The individual fibers are blended with differently colored or hued fibers produced in the same way, and/or with greige or colored staple fibers, to produce a blended composite of fibers. The blended composite is then spun, for example ring spun or open end spun, into a final colored yarn. Rayon fibers may especially effectively and uniquely be utilized, although almost any fiber or mix of fibers can be used.

An annular flange portion extends radially outwardly from the rear of the hub portion and has an inside surface for being positioned adjacent the end surface of the yarn carrier.

Abstract: Thread is wound between spin hooks (20) and anchor hooks (26) and around loop-pins (TP, BP) to form two thread groups, one extending between a first spin hook (20) and the anchor hook (26) and the other extending between the anchor hook (26) and the second spin hook (20). The spin hooks (20) are both rotated in the same direction, at the same speed, for separately twisting the two thread groups. Then, the two separately wound thread groups are moved laterally together and allowed to unwind and at the same time wind together in the opposite direction, to form a single fly fishing leader, or the like. The thread is wound to form twelve thread strands in a butt section of the leader, ten thread strands in a mid-section of the leader and eight thread strands in a tip section of the leader (FIG. 11). As a result, the leader that is formed tapers from the butt end to the tip end.

Abstract: A method for cotton purification is described, where the cotton is subject to a purification process in water. The process solution contains calcium hydroxide and a non-ionic detergent wetting agent. Following this processing the cotton is rendered hydrophilic. The cotton is carried in a net with simultaneous removal of the adsorbed processing solution. It is then washed and bleached with H.sub.2 O.sub.2 or ClONa in a two-stage process. The effluent water is processed by anaerobic digestion in the thermophilic region for the production of biogas. The effluent water from the anaerobic digestion process is further processed by aerobic biological treatment. The whole process operates with energy self-sufficiency without resulting in environment pollution. Finally, a high purity cotton is produced with high water absorptivity which is suitable for spinning for the production of quality cotton yarns suitable for weaving quality fabrics or dyeing.

Abstract: A method for manufacturing a twisted yarn includes the step of removing two rovings from two separate supplies and passing each roving through a separate drawing device. From each roving a separate spun yarn is produced by ring-spinning.

Both spun yarns are then guided together to a winding device positioned below the lower one of the hollow spindles. The hollow spindles are rotated as a function of the winding speed of the winding device such that a twist of the spun fibers is at least partially canceled.
