ABSTRACT:
A stop spindle for textile machines, particularly spinning and twisting machines. A ferromagnetic clutch element, formed e.g. by a circular disc, is mounted axially displaceably between the whirl of the stop spindle and a brake lining behind which there is mounted an electromagnet. The brake lining is made of non-magnetic material and is mounted between the pole shoes of a permanent magnet. The electromagnet is energized by an electric pulse so as to create a magnetic field which is additive with respect to the magnetic field of the permanent magnet, whereby to start the driving of the spindle; the electromagnet is energized by an electric pulse so as to create a magnetic field which is substractive with respect to the magnetic field of the permanent magnet whereby to stop the driving of the spindle and to brake it.
