Abstract

PURPOSE:To obtain a continuous reinforced cable without increasing it outer diameter, by using a friction driving type extruding device to extrude Al or an Al alloy around at least an optical fiber cable and a reinforcing metallic wire and then drawing out both the fiber line and the Al or Al alloy. CONSTITUTION:For an extruding device, a supply pipe 10 is formed by the groove face 7 of a driving wheel 6 and the inner wall face 9 of a fixed shoe block 8, an extruding room 12 connects to the pipe 10 with a pipe extruding dice 13. At the same time, the core material inserting holes 14 and 14' pierce through the block 8 for insertion of the optical fiber cable and reinforcing metallic wire 3. The hollow mandrels 15 and 15' are connected to the tips of the holes 14 and 14' respectively. The Al 17 supplied to the pipe 10 is sent further into the pipe 10 by the revolution of the wheel 6, and an aluminum sheath 2 is extruded from the dice 13. At the same time, both the fiber cable 1 and the wire 3 are inserted and then drawn out at one time. Thus the sheath 2 is coated around the cable 1 and the wire 3 for an optical fiber cable 5'.
