ABSTRACT:
In the manufacture of a fiber reinforced plastic armored cable, long reinforcing fibers are impregnated with an uncured thermosetting resin and formed into a predetermined shape to obtain a plurality of rod-like members with the thermosetting resin held uncured. Then the uncured rod-like members are passed through a die of a melt extruder, by which the rod-like members are each coated with a thermoplastic resin layer. The coated layers of the rod-like members are immediately cooled to simultaneously form a plurality of fiber reinforced plastic armoring strands with the thermosetting resin held uncured. The armoring strands thus obtained are wound around a cable which is fed while being rotated. The cable having wound thereon the strands is passed through a die portion of a melt extruder, by which the cable is sheathed with a thermoplastic resin layer which is immediately cooled and solidified. The sheathed cable is guided into a curing tank using a liquid as a heating medium to cure the thermosetting resin in the armoring strands. Thereafter, the sheathed cable is wound onto a drum via a rotary take-up device.
