ABSTRACT:
In monitoring a continuous sequence of work positions on a textile machine for thread breakage, a magnetic probe is driven along a path adjacent the ring traveler at each work position so as to generate a signal upon detection of the traveler as it rotates with the thread and provide no signal when the traveler ceases to rotate due to thread breakage. To simplify the electrical connection to the probe, the drive arrangement for the probe includes at least one conductive metallic drive band connected to the probe and to a driving source for moving the probe along the path past the work positions. A detector is then coupled to the drive band to detect the electrical signals carried thereby from the probe.
