摘要： A method of producing a synthetic resin rod (wire), comprising: an extruding step of extruding a synthetic resin rod; a pre-cooling step of spraying a cooling medium on the rod to pre-cool the rod extruded down to a temperature (T° C.) satisfying the following condition: T≦{(a softening point of the synthetic resin)+5} [° C.]; and a main cooling step of letting the rod thus pre-cooled pass through water to cool the rod.

摘要： In an optical cable according to the present invention, a grooved spacer has a plurality of grooves in its circumference, and the cutting direction of the grooves is inverted at predetermined periods. Optical fibers are received in the respective grooves. On the circumference of the grooved spacer, a linear member is provided around the grooved spacer along the longitudinal direction of the optical cable at a predetermined period. The linear member is fixed to the grooved spacer by welding or bonding in the portions where they touch the outer circumferences of the grooved spacer so as to restrain the optical fibers. The linear member restraining the optical fiber to be taken out are cut in positions above the groove in which the optical fiber is received so that the required optical fiber can be taken out.

摘要： An apparatus for, and method of manufacturing an optical fiber cable whereby stable transmission characteristics, such as length and tension, are maintained throughout a specified length of the cable. A slotted rod having spiral grooves formed longitudinally on the surface thereof is hauled by a hauling device, optical fibers or optical fiber ribbons are inserted into the spiral grooves, and a binding is applied onto the outer surface of the slotted rod to form the basis for an optical fiber cable stranding. The optical cable stranding with the optical fibers or the like inserted in the spiral grooves and with the binding applied thereon is wound around a guide wheel, thereby maintaining stable transmission characteristics throughout a specified length of the cable, and then further hauled. The guide wheel is rotatable about a rotary axis perpendicular to the hauling direction of the slotted rod.
