摘要： An apparatus for assembling an optical cable comprises a spacer paying-out portion 7, a stationary ribbon supply unit 9, a gathering portion 14 and a taking-up portion 21. The spacer paying-out portion 7 supplies a spacer 2 having a spiral groove in the surface of a long spacer body from a supply reel 1 while revolving around a line axis X-X. The stationary ribbon supply unit 9 supplies a plurality of optical fiber ribbons 11. The gathering portion 14 forms the optical fiber ribbons 11 sent out of the stationary ribbon supply unit 9 into a cable core 15 by holding the optical fiber ribbons 11 within the spiral groove of the spacer 2 sent out of the spacer paying-out portion 7 and running forward while rotating on its center axis. The taking-up portion 21 winds the cable core 15 on a taking-up reel 20 while revolving around the line axis. A winding roller 8 (8′) having an rotational direction identical to an rotational direction of the supply reel 1 of the spacer 2 and used for winding the spacer 2 or the cable core 15 is installed adjacently before and after the gathering portion whereby to revolve the winding roller around the line axis in synchronization with the revolution of the spacer paying-out portion 7. Accordingly, it is possible to prevent a twisting of the spacer in the gathering portion resulting from a winding habit of the spacer during a step of assembling cables.

摘要： In a method of manufacturing a self-support optical cable, a support wire and an optical cable body arranged in parallel are fed with each other; a sheath into an eight figure shape is extruded by an extruder to collectively coat the outer circumferences of the support wire and the optical cable body with the sheath, and thereafter, the self-support optical cable is cooled before hardening while the cable passes through a plurality of guide wheels so that an excess length is given to the optical cable body. In this method, the guide wheels are disposed in a cooling water tank in a manner so that a guide wheel contacting with one side of the self-support optical cable with the sheath in a softened state and another guide wheel contacting with the other side of the self-support optical cable with the sheath in a softened state are disposed alternately in the feed-out direction, said excess length is controlled based on the tension of the support wire, or the tension of said optical cable body at an inlet portion of said extruder is reduced by a tension reducing device.
