Title: Two-for-one twister spindle drive
Inventor: ANTON PAWELETZ
IPC: H02K17/20
Filed: 1993-05-28
Abstract: The spindle for a two-for-one twister is a relatively low inertia spindle keyed to a squirrel cage rotor (3). It has a groove geometry where the web (11) to close the groove gives a timed saturation from the start of switching-on. When the nominal rotary speed is achieved, there is a low slip and a very stiff loading action.     Pref. the slow start-up and the stiff loading action is determined by the depth of the grooves (10) in the rotor (3). The speed/time characteristic of the activated spindle follows an S-shaped path. The ratio of the web (11) width (bs) to the mean tooth width (bz) of the grooves (10) in the rotor (3) is set for the best performance where the dynamic start-up characteristic is gentle and the loading characteristic of the induction motor (4) is very stiff. The larger cross section of the deep grooves (10) is within a ratio of 0.05-1.2. The yarn is fed from below into the rotating unit of the spindle. The yarn emerges radially from a rotating twisting plate to form a yarn balloon round a fixed bobbin to the twisting point with an inner bobbin yarn. The force on the yarn is smoothed by the rotation of the spindle and the axial draw tension.
