The deflection roller 2 is mounted in the yarn head rotor 1 by bearings 6 at both ends of the deflection roller 2, wherein the two ball bearings 6 are each enclosed by a housing 7 of the yarn head rotor 1, which is closed with a cover 8, and yarn guiding eyelets 9, guiding the inner and outer yarns 17, are arranged upstream of the deflection roller 2 in such a way that they supply both yarns of the deflection roller between the two ball bearings 6 to the yarn head rotor 1.

A method for starting a spindle of a cabling or two-for-one twisting machine, wherein a yarn reserve is formed on a take-up package, the machine has a workstation having a spindle pot for holding a first feed package and having a spindle rotor with a lateral outlet below the spindle pot, an outer yarn from one feed package is wound around an inner yarn from another feed package and the outer yarn is guided through the spindle shaft and its lateral outlet in a balloon orbiting the spindle pot to a yarn-guiding device above the spindle which merges the two yarn supplies, and a winding device in which the produced twist is wound onto the take-up package. A ratio of the take-up speed of the twist to the rotation speed of the spindle rotor is increased in comparison with the production data is used during creation of the yarn reserve.

A device and a method for detecting a distance from a balloon to an ingot tank is provided. The device comprises a set of photoelectric transmitting tube and photoelectric receiving tube which are arranged in a height range of a balloon, Wherein a light beam between the photoelectric transmitting tube and the photoelectric receiving tube is arranged to be tangent to an appropriate balloon, and is used for detecting whether the balloon is located at an appropriate position according to a number of pulses received by the photoelectric receiving tube in one period of rotation of the balloon.

A workstation (1) of a two-for-one twisting or cabling machine which comprises a rotatably mounted spindle (2) and a balloon-yarn-guide-eye (9) height-adjustable by means of a drive (18, 29) coupled to a control device (20) which controls the drive (18, 29) in such a manner that it displaces the balloon-yarn-guide-eye (9) between operating positions (AP.sub.1, AP.sub.2) dependent upon production parameters and a resting position (RS) advantageous in the case of production interruptions and transient operating phases associated with the latter. A device (21, 23, 24, 25) is present for detecting a measured value (i), which is made available to the control device (20) and which causes the control of the drive (18, 29) to change the position of the balloon-yarn-guide-eye (9).

Methods of using a two-for-one twister are described to twist at least three yarns in various ways to provide desirable yarn constructions. For some embodiments, at least two yarns can balloon about one or more bucket yarns. For some embodiments, bucket yarns can be provided in an innovative manner, whether side-by-side and/or a first bucket yarn feeding through a second supplied bucket yarn.

At least two pairs of magnets are arranged near one another on supports, the pairs of magnets and the supports form, when an item to be stabilized is in a required angular position, a closed magnetic circuit (except for the air gap), with magnets placed in such a direction that their north and south poles successively alternate with one another along the magnetic circuit, an item, sensitive to the magnetic field, is attached to the fixed part and placed inside the closed magnetic circuit, the sensitive item supplies a logic output state corresponding to the item to be stabilized in the required angular position when the detected field is less than a predetermined maximum threshold, and a logic state corresponding to the item to be stabilized not in the required angular position, when the detected field is greater than a minimum predetermined threshold.
