Abstract
Strand break detector for monitoring a number of straightened strands extending along a number of predetermined paths, with regard to a broken or missing strand. An optical transmitter with light-receiving means is arranged to supply, at relative motion between strands and transmitter transversely of the strands, a signal for each passing strand. A shield is arranged as a spacer in front of the light-receiving means and forms an inlet for light to the light-receiving means, and a slide surface for guiding the strands engaging the slide surface, past the light inlet at relative movement between the strands and the transmitter.
