Abstract: The thread monitor serves to detect the passage in a textile machine of a thread (F) moving in a direction transverse to the thread length. The monitor contains a pivoting member (B) which can be actuated by the thread and a sensor (7) monitoring the actuation of this pivoting member. The pivoting member (B) is designed in such a way that, during the passage of the thread, the pivoting member (B) is deflected from its rest position and then returned into its rest position, the sensor (7) being designed for detecting this return. The pivoting member (B) is elastic and in one-piece and the sensor (7) is sensitive to pressure. The monitor may be used in thread storage means and thread-transfer devices, particularly those in weaving and in warp-thread preparation apparatus.

Abstract: The invention relates to a thread movement sensor comprising an arm with at least one thread guide. The invention solves the problem of sensitivity of the sensor to the vibrations of the machine by making a part of the arm an element of a magnetic circuit of coil, the latter being connected to the control circuit of a knitting machine.

Abstract: The apparatus is particularly adapted for detecting breakage, run-out or excessive slackening of running sliver strands passing from a creel to the drafting rolls of a textile drafting machine, and includes reed switches which are actuable by movement, into proximity therewith, of magnet-carrying members which normally are maintained distal from the switches by engagement with the sliver strands. The reed switches are protectively mounted and are so located with respect to the magnet-carrying members as to minimize the number of reed switches required for operation of the apparatus. The channelled mounting for the reed switches also provides separating vane guides for the adjacent running strands of sliver, the guide walls having rounded end protuberances to effect better separation; both the guide elements and magnet-carrying members being coated with a smooth plastic to obviate snagging of sliver.
