ABSTRACT:
In an optical fiber cabling line where a grooved ring is axially drawn at a translational speed, there is provided a device designed to insert optical fibers in helical grooves of the ring. The fibers are unwound, are drawn through a rotating plate and converge following cone generating lines towards the device. In order to avoid the use of fiber-guides coupled directly in rotation with the ring, the device comprises a quill rotationally stationary and coaxial with the ring for laying the fibers into the grooves of the ring, and means, such as two worm screws set orthogonally to the ring, arranged after the quill in the travel direction of the ring and mechanically uncoupled from the ring for thrusting the fibers to the bottoms of the grooves. The worm screw also contributes to align the fibers as they leave the plate, with the ring grooves within the quill.
