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.
Claims6
A weft feeler device for a loom comprising a movable assembly synchronously oscillatable with the loom and including a feeler subjected to the retaining effect of a weft, a photo-electric system comprising an optical beam generator and a photo-electric sensor, a slidable unit mounting said feeler on said assembly for sliding movement relative to said photo-electric system, and an intercepting screen mounted on said slidable unit for movement with the feeler to block passage of the beam when the feeler is not retained by the weft whereby a signal can then be generated, said assembly further comprising a body with two spaced extensions, one carrying the optical beam generator and the other the photo-electric sensor;
- said screen being a longitudinally oriented finned screen positioned to be inserted in the space between the two extensions to block the optical beam.
