Abstract: A method for the manufacture of an elastic twisted yarn has at least one outer yarn wound or twisted around an expanded, elastic core yarn. In a first process step the outer yarn is wound around the core yarn with a winding speed providing less than the nominal twist of the finished twisted yarn. The thus formed intermediate yarn is wound up and then twisted in the same direction of rotation in a second process step. In the first process step the outer yarn is wound with the help of a double-pot spindle at a winding rate providing a twist of above 50% of the nominal twist without forming a balloon around the core yarn, and the second process step is carried out on a double-twist spindle.

Abstract: A hollow spindle, in particular for the manufacture of elastic twisted yarns, has a thread channel (9) extending coaxially with respect to the axis of the spindle (A), through which thread channel is axially moved a yarn (6), in particular an elastic core yarn. The thread channel (9) has ribs (10) on its inner surface (8a), which extend in peripheral direction or helically and project inwardly over the surface (8a), so that the yarn (6) running through the thread channel (9) rests only pointlike on the ribs, otherwise, however, is supported at a distance from the inner surface (8a).

Abstract: An integrated doubling and twisting method includes the step of arranging at least two supply bobbins coaxially above one another in a protective pot of a bobbin support. The at least two supply bobbins are connected to one another, and the bobbin support together with the at least two supply bobbins is rotated. The individual spun yarns from the bobbin supports are removed in the direction of the axis of rotation of the bobbin support. One of the individual spun yarns is removed in clockwise direction and another one of the individual yarns is removed in counterclockwise direction. This feature can also be applied to a method in which a balloon limiter is provided and the individual yarns are guided through a hollow spindle axle.

Abstract: A multi-twisting spindle has a hollow spindle axle defining the axial direction of the twisting spindle. A bobbin support including a support bottom and a protective pot is rotatably connected to the hollow spindle axle. A rotor disk is fixedly connected to the hollow spindle axle. A balloon limiter is connected to and rotates with the rotor disk. The protective pot is positioned radially inwardly in the balloon limiter. A gap is formed between the balloon limiter and the protective pot. The protective pot is driven in a rotational direction opposite to the rotational direction of the balloon limiter. The rotor disk has a yarn guide channel connected to the hollow spindle axle and extending radially outwardly away from the hollow spindle axle. A deflection channel is connected to the yarn guide channel and has an outlet that opens into the gap. A yarn catch ring is arranged axially spaced below the support bottom in a radially outer area of the support bottom.

Abstract: A method of building a yarn reserve at a balloon limiter for a yarn guided after emerging from a spindle rotor into a yarn guide channel includes the step of connecting a yarn guide eyelet to an upper end of a balloon limiter so as to be positioned at an angular distance relative to an exit location of the yarn at the spindle rotor. The angular distance is adjusted between 20.degree. and 120.degree. as a function of operating conditions. The yarn is guided for building a yarn reserve through the yarn guide eyelet. The multiple twisting spindle for performing the inventive method has a spindle rotor having an exit location for a yarn and a rotating balloon limiter surrounding the spindle rotor and having at an upper end thereof at least one yarn guide eyelet. The yarn guide eyelet is spaced at an angular distance relative to the exit location of the yarn at the spindle rotor.
