DEVICE FOR DETECTING THE MOVEMENT AND / OR THE PRESENCE OF A STRIP FORMED OF TEXTILE FIBERS CONSTITUTED BY COTTON AND / OR CHEMICAL FIBERS, PARTICULARLY IN A DRAWING SECTION

摘要

A strip formed of textile fibers passes through a chamber (10 ') in a stretching section. The strip is associated with a detection device whose radiation path (L) is essentially perpendicular to the direction of movement of the strip. The strip is movable on a path in the chamber approximately perpendicular to its direction of circulation (B) and can be successively located inside or outside the radiation path (L). Application in particular to the manufacture of strips formed from textile fibers.
