Abstract (en)
Electronic warp stop motion device, of the type wherein the breaking of a warp yarn, causing the dropping of a corresponding lamina, interrupts a luminous beam between the sending part and the receiving part of one of a plurality of photoelectric cells, provided to each control a corresponding row of warp yarns, to have said breakages signalled and to stop the loom. The photoelectric cells of said device use beams of coherent light produced by a laser source.
