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.

摘要： Torsional fixation portions holding an SZ slotted body having spiral grooves turning over alternately in the surface of its column body are provided to prevent the SZ slotted body from being distorted, and between the torsional fixation portions, a groove fixation device with one or more protrusion projecting into the spiral grooves of the SZ slotted body to prevent the grooves front turning in the sectionally circumferential direction in provided. The SZ slotted body is passed through the groove fixation device while the SZ slotted body advanced straight. Optical fibers are introduced and stored into the grooves of the SZ slotted body in the vicinity of the groove fixation device, and immediately a pressing winding consisting of yarn, tape or the like is given onto the SZ slotted body.
