ABSTRACT:
Yarn breakage stop motion device for textile machines, in particular for tufting machines, having a number of plates corresponding to the number of yarns to be monitored, utilize plates equipped on both ends with an eye each. One eye serves to guide a yarn to be monitored and the other eye supports the plate on a carrier axle. All plates together form in their entirety a register. A photocell acting on the drive mechanism of the textile machine is arranged such that the pivoting of one or more plates will be detected by the photocell. A plurality of spacer rings are held clampingly against each other on the carrier axle, with each of the spacer rings having on one side an annular shoulder surrounding the carrier axle and the eye serving to support the plate being provided with an aperture, so that the diameter of the eye corresponds to the external diameter of the annular shoulder and the width of the eye aperture to the diameter of the internal opening of the spacer ring or the diameter of the carrier axle.
