Embodiment Construction
[0022] The yarn guiding device consists of a yarn guiding device 1 arranged above the spindle, which has a twisting part 10, which contains a braking mechanism. The braking mechanism consists of a tappet 13 which has a core 13' extending coaxially with the axis of rotation around which the upper unfinished yarn F coming out from the spindle 3 to the outlet of the draw frame surrounds. On the core member 13', there are an upper edge 15 and a lower edge 15' on which the yarn F passed through the yarn-guiding device 1 rests and is brought into rotation when the twisting member 10 turns.
[0023] The part facing the spindle 3 on the twisting member 10 is used as a magnet, and forms a coupling magnet with the accessory 33 on the spindle 3 that is also equipped with a permanent magnet 31, so that the twisting member 10 rotates at the same speed as the spindle 3. The distance between the spindle fitting 33 and the twisting element 10 is determined by the necessary magnetic field to e...
