Abstract
An optical weft stop motion for looms with a U-shaped reed includes an optical emitter, an optical receiver, and a unitary optical conductive plate attachable disposed between the reed lamellae. The plate is provided with a recess which is substantially congruent with and adjacent to the recesses in the U-shaped reed. The optical conductive plate is provided with internal light reflecting side walls which guide the light in the shape of a beam from the emitter through the complete or almost the complete recess of the plate and reflect it further to the receiver.
