DISPOSITIVO PARA AJUSTAR EN UNA POSICION PREDETERMINADA EL ROTOR DE UN HUSO DE HILAR O RETORCER, ESPECIALMENTE DE UN HUSO PARA DOBLE TORSION DE HILO.

摘要

In a textile yarn processing machine, such as a twister, spinning frame or the like, having a plurality of spindle assemblies and each spindle assembly including a driven rotating rotor mechanism; the improvement of selectively operable devices for re-positioning the spindle rotor mechanism to a predetermined threading position for threading up of the spindle assembly. The re-positioning devices include a nozzle for directing a jet of compressed air eccentrically and obliquely against the underside of the rotor mechanism for rotating the rotor mechanism to re-position the rotor mechanism. The spindle assembly further desirably includes air operated devices for threading the yarn through the spindle assembly and the re-positioning devices further preferably include devices for actuating the threading devices upon completion of the operation of the re-positioning devices.
