Abstract
Apparatus for inserting optical fibers into helical grooves in a plastic core advanced through a rotatable, rigid body which has conduits for guiding the fibers from bobbins mounted on a rotatable cage into the grooves, the ends of the conduits engaging the walls of the grooves which cause the body to rotate as the core is advanced, said apparatus having drive means for advancing the core separate from the drive means for the rotatable cage and having detecting and control means for detecting angular and direction of rotation differences between the cage and the rigid body and correcting such differences by control of the rotation of the cage by its drive means.
