Abstract
In a reeling machine a multiplicity of yarns are pulled from respective supplies and wound up on a beam and each yarn is associated with a sensor which produces an output whose state indicates if the respective yarn is broken or not present. Each sensor is periodically scanned to read the state of its output and the reeling machine is stopped when one of the scanned outputs corresponds to a broken or not present condition of the respective yarn. An output is simultaneously generated indicating exactly which yarn is broken or not present. The sensor are connected to a matrix and the matrix is scanned to read the sensor outputs.
