Abstract
A filling-thread monitoring device for jet looms in which a filling thread is guided during its introduction into the shed of a loom in a first guide channel which is formed by spaced members and is partially open on its side, contains a first filling thread stop motion means for the giving off of a signal when the filling thread introduced does not reach its normal length and a second filling thread stop motion means spaced from the first stop motion means in order to give off a signal when the filling thread introduced exceeds its normal length by a predetermined amount. Between the two filling thread stop motion means, a guide member is arranged which extends over the space which is free of warp threads and has a second guide channel which lies in the extension of the first guide channel and is closed in the filling direction. No dust can deposit in this closed second guide channel so that erroneous signals of the second filling thread stop motion means, produced by accumulations of dust which have been blown away, do not occur.
