Method and device for monitoring the rotation of ring travellers on a ring-spinning or ring-twisting machine

摘要

The invention relates to a method and a device for monitoring the rotation of ring travellers in a ring-spinning or ring-twisting machine, in which a signal is transmitted to a control unit by a sensor during the rotation of the ring traveller 3. In this case, the variation in a light beam directed onto the path of rotation of the ring traveller 3 brought about by the rotation of the ring traveller 3 is sensed. Light waveguides 5 can be arranged between the light source 6 and regions of the paths of rotation of the ring travellers 3 and the photosensors 7 in order to carry out this method. <IMAGE>
