Abstract (en)
[origin: EP1270780A2] The system to register a leno yarn beak at a loom leno selvage unit has at least two guide arms for at least two leno yarns (2,3), which are twisted together by the rotation of the arms. A monitor (13,14) registers the natural oscillation of the two arms (12). The yarn break monitor is located at the front shed of the loom, between the leno selvage unit (10) and the loom shafts. The oscillation is monitored without contact, using a magnetic field from the magnetically conductive arms and a field sensor. The sensor readings are processed by an evaluation unit, which compares signals for intact and broken yarns, and is connected to a signal transmitter. The arms are fitted with permanent magnets, and the sensor has an inductive action through a coil or a Hall sensor, or it has a capacitative operation.
