Ring traveller monitor - has an inductive sensor and magnet to register the presence and to position the traveller for automatic yarn break repair

摘要

To give an automatic yarn repair action at the workstation of a ring spinner, the position of the ring traveller is monitored magnetically at the traveller through drive which operates the ring traveller and/or the held position of the traveller. The presence of the ring traveller is determined by recording the periodic passage of the traveller through a magnetic field, and the traveller is positioned by the application of magnetic force. ADVANTAGE - The system identifies the position of the ring traveller for the yarn repair to be effected without searching.
