ABSTRACT:
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.
