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.

The disclosure describes a yarn twisting machine in which a hollow spindle rod is fixedly connected with a motor that drives the hollow spindle rod to rotate, a twisting disc and a yarn storage disc are fixedly connected with the hollow spindle rod and rotate along with the hollow spindle rod, the yarn storage disc is provided with yarn outlets, which communicate with inner yarn channels of the hollow spindle rod spindle tanks for accommodating inner yarn packages are connected with the hollow spindle rod through spindle rod bearings, and the spindle tanks are immobile.

An outer-yarn brake (14) for a cording or cabling machine with at least one workstation comprising a bobbin rack (2) for holding at least one feed bobbin (4), a spindle (12) for the rotation of a yarn (6) withdrawn from the feed bobbin (4) around a bobbin pot associated with the spindle (12), and a yarn-guide channel (10) for guiding the yarn (6) received via a free end-portion (8) of the yarn-guide channel (10) to the spindle (12). The outer-yarn brake (14) can be arranged in the yarn running direction of the withdrawn yarn (6) between the feed bobbin (4) and the yarn-guide channel (10) to guide through the withdrawn yarn (6) and comprises a clamping portion for defined braking of the running yarn (6). The outer-yarn brake (14) can be coupled to the free end-portion (8) in order to form a yarn input for the yarn-guide channel (10).

The present invention relates to an apparatus for manufacturing reinforcement meshes and spinning stations therefor. Reinforcement rods to be joined with the spinning wires are supplied by advancing means from the rear end of the apparatus, and a special mechanism prevents that the wire breaks during its encounter with the reinforcement rod.

A yarn twisting device includes a frame and following components on the frame: a hollow shaft, in which a passage is provided for a yarn passing therethrough; a drive mechanism configured to drive the hollow shaft for rotation; a winding mechanism driven by the hollow shaft for rotation to rewind the twisted yarn; a speed reducing mechanism for transmission coordination between the hollow shaft and winding mechanism. The twisting device is in simple structure and less twisting tension, which is available for continuous twisting of a single yarn and combined twisting of multiplied yarns.

A spool of yarn of natural, synthetic or artificial textile fibres, with the torsion value of the plied yarn (?) throughout the spool (1) being variable, and being associated with the instantaneous winding/unwinding diameter (DI) of the spool (1), equal to ? (tpm)=1/(DI*?) such that, on unwinding the yarn as twisted in a first direction N-S, the torsion value of the yarn, once unwound as twisted (?) is constant throughout the spool and is essentially equivalent to 0 tpm, and such that, on unwinding the yarn as twisted in a second direction S-N, opposite to the first direction, the torsion value of the yarn, once unwound as twisted (?), is variable throughout the spool and is equivalent to ? (tpm)=2/(DI*?). Process for the generation of the spool disclosed, and yarn twisting machine for the generation of the spool disclosed.
