摘要： PURPOSE:To prevent any torsion of a flat type cable by embedding a reinforcing wire made of a parallel bundle filament, another reinforcing wire made of a braided filament and a third reinforcing wire made of these composite filament in a covering so as to be respectively extended along the longitudinal direction of the flat type cable. CONSTITUTION:A reinforcing wire 5A made of a parallel bundle filament 4 formed through the process of bundling plural element-wires 31 respectively in parallel with one another without intertwisting them, another reinforcing wire 5B made of a single or plural braid-covered braded filament 6 formed through the process of braiding plural element-wires 32 together and a third reinforcing wire 5C made of a composite filament 7 formed through the process of providing the braided filament 6 outside the parallel bundle filament 4 are embedded each in a covering 2 at its bisymmetric position at an appropriate distance from a central position X on the cross section of a flat type cable in such a condition as to be extended along the longitudinal direction of the cable. Or some -type one of the above-mentioned reinforcing wires 5A, 5B, 5C is embedded in the covering 2 at the center X of the cross section of the flat type cable at large in such a condition as to be extended along the longitudinal direction of the cable.

摘要： PURPOSE:To eliminate the fear of occurrence of any crack, breakage and disconnection due to residual strain by winding fiber reinforced plastic wires around the outer periphery of an electric cable core in a spiral after heating up to the fixed temperature at which the self-heating thereof is started to be hardened, thus obating the aromored cable wounded with the fiber reinforced plastic wires perfectly hardened by the self-heating. CONSTITUTION:Prior to the winding around the outer periphery of an electric cable core in a spiral, fiber reinforced plastic wires, which is not perfectly hardened, are heated up to the fixed temperature at which the self-heating is started to be hardened. Thereafter, the wires are wound around the outer periphery of the electric cable core in a spiral. With this arrangement, since there remains such a flexibility as being necessary for winding even if the hardening of the fiber reinforced plastic wires is progressed so that it is possible to perform the winding around the electric cable core with a sufficient winging force.

摘要： PURPOSE:To prevent the generation of cracks by a stress and resulting in a cutting off of the wire by heating a linear body at a hardenable temperature to promote to harden to almost a perfect hardening, and after that, winding the periphery of an elastic cable with the linear body up to a perfect hardening. CONSTITUTION:A reinforced plastic linear body 51 is conveyed through a preheating zone 14 to a heating zone 15 of a heating device 13, where it is heated by raising the temperature up to a hardening temperature, and the hardening is promoted near to a perfect hardening. The linear body 5 is advanced further, and stranded around an elastic cable 1 which has run through the center of a stranding device 10, at the position of a stranding mouth piece 18. The linear body 51 stranded to the periphery of the cable 1 after passing through the stranding mouth piece 18 is released from the ambiance of the hardenable temperature, and the hardening is promoted to make into a perfectly hardened reinforced plastic linear body 5. As a result, a reinforced plastic wire armored cable which has no fear of generating cracks resulting from the residual stress (bending deformation) can be obtained.

摘要： PURPOSE:To prevent the cable in the title from waving itself, even in the presence of any external force such as bending or twisting it, etc., by wrapping a tape made of a synthetic resin which melts at a temperature given at the time of making extrusion process to form a coating of sheath around a twisted wire core, then applying filled up extrusion to the sheath for coating the taped wire core. CONSTITUTION:A tape made of a synthetic resin which melts with heat given at the time of making extrusion process to form a coating of sheath 7, is wrapped around a twisted wire core 5 formed by twisting a plurality of insulated wire cores 2, 3, 4 so that a meltable taped layer 8 is formed. Meanwhile, a thermoplastic synthetic resin having its melting temperature of less than about 200 degrees Centigrade is used as the synthetic resin for forming the tape, and the thickness of the tape is specified to an extend from 20 to 150 micrometers. This meltable taped layer 8 melts and softens by the heat of a molten resin being formed into the sheath 7 when filled up extrusion is applied to form a coating of sheath 7, and the taped layer 8 which has melted and softened is further pressed into gaps between respective intertwisted portions of the insulated wire cores by the pressure of the molten resin. A filled up sheath type moving cable can be thus obtained with satisfactory resistance to any bending, which prevents the cable from waving itself even if bending or twisting force is exerted on it.

摘要： PURPOSE:To enable plastic wire outer sheath to be made efficiently and certainly by forming a reinforced plastic wire shaped body in a unhardening, half- hardening state into spiral form with a defined bore and heating it so as to be wound on to an electric cable. CONSTITUTION:A reinforced plastic wire shaped body W21 in a unhardening state or half-hardening state is formed into spiral form with a little smaller bore than the outer diameter of an electric cable W1. This reinforced plastic wire W22 of spiral form is heated to a defined temperature and is wound on to the electric cable W1. The spiral form plastic wire W22 is hardened by heat and is wound on to the electric cable W1 by defined fastening force in a state of that stress is hardly generated so that a reinforced plastic wire W is formed. The plastic wire shaped body W21 is heated independently for a short time, and thereby manufacturing efficiency is high.
