摘要
A process and apparatus for laying optical fibers in the helical grooves of a core for an optical fiber telecommunication cable in which the rotatable bobbins carrying the optical fibers are held in axially fixed positions while the core with helical grooves and the fibers are fed to and through a rotatable fiber inserting device which has projections extending into the grooves which cause rotation of the device as the core is advanced. Between the bobbins and the fiber inserting device there is a supporting tube through which the core passes and the outer surface of which engages and supports the fibers. The downstream end of the tube terminates in advance of the fiber inserting device so that the fibers may enter the grooves in the core at the fiber inserting device.
