Abstract
A continuous process for manufacturing an optical cable element in which a central draw core is rotated with a periodically reversing direction of rotation. The draw core is then provided (i) with synthetic resin tubes in which one or more optical fibers are incorporated, or (ii) with an extruded synthetic resin sheath with grooves in which one or more optical fibers are laid. As a result of the rotation of the draw core, the grooves in the synthetic resin sheath or the synthetic resin tubes follow helical paths with periodically reversing directions of rotation.
