ABSTRACT:
A weft feeler device for a loom comprising a movable assembly sychronously oscillatable with the loom and carrying a sliding unit on which is mounted a feeler, subjected to the retaining effect of a weft, and a screen. The assembly carries a photo-electric system comprising an optical beam generator and a photo-electric sensor. Upon breakage of a weft thread, the slidable unit is not retained and the screen occupies a position in which it blocks the optical beam.
