ABSTRACT:
A weft yarn break for a power loom has first and second sets of hoops. Each set of hoops has at least two hoops which are spaced apart and essentially parallel to each other. A mechanism drives at least one of the sets of hoops about a rotational axis so that the first and second set of hoops have a relative swivelling, motion. A transversing hoop is disposed in the running direction of the weft yarn and includes an inclined surface located across the running path or direction of the weft yarn. The weft yarn is shifted up and down the inclined run-up surface as the first and second set of hoops are swivelled relative to each other.
