Abstract
A yarn monitoring device comprises in association with each doubling spindle (1) a sensing arm (7) monitoring the upwardly directed yarn run between yarn guide eye (3) and feed roller (V), which arm is mounted by means of a mounting bush (9) for limited swinging on a rocker shaft (6). The mounting bush (9) comprises a slot (12) extending in its circumferential direction, in which engages a stop pin (11) extending radial to the rocker shaft (6) and fixed relative thereto. In the slot (12) is a lining in the form of a substantially U-shaped clip (13) of spring steel, whose semi-circular connecting part (13b) lies at the end surface (12b) of the slot (12) directed away from the spindle and whose U-arms (13a) extend parallel to the side walls (12a) of the slot (12), abut thereagainst and are inwardly bent at their free ends (13c) so that they grip on to the stop pin (11) in the swung up position of the sensing arm (7).
