Abstract
A device is disclosed, as an attachment to a spinning, or a doubling frame, for stopping the rotation of the spindle and the sliver feed whenever a sliver or a thread breaks and for giving, at the same time, a warning signal (e.g. a luminous signal) to a watching operator. The device comprises a thread feeling whisker connected to a circuit which controls electromagnetic clutches connected to the spindle, and the spindle braking and stopping mechanism is connected by a flexible cable to a sliver-pinching press so that as soon as the spindle is being braked and stopped the sliver is pinched and sliver feed is discontinued. The electric circuit also comprises an indicator lamp.
