| Method of producing a continuous flexible tubular conduit having a plurality of helically wound reinforcing-electrical wires is provided wherein the apparatus has means for forming a plurality of wires into a corresponding plurality of substantially identical continuous non-rotating helical coils without entanglement of such wires and an extruder head for extruding a polymeric tube around the coils with the coil turns coaxially aligned and alternately arranged to complete the tubular conduit. | ||||||

| A pair of large wire supply rolls are rotatably supported by a cantilevered tubular shaft, and corresponding wires extend from the rolls to a coil forming rotor which is also supported by a cantilevered tubular shaft aligned axially with the roll support shaft. Wire is withdrawn from the wire supply rolls by rotation of the rotor which includes precisely driven wheels for feeding the wires through corresponding sets of casting rollers to form a continuous double helix nonrotating coil. A non-rotating mandrel projects through the roll support shaft for supporting the helical coil as it is being formed and progresses axially between a set of endless belts which feed the continuous coil from the coil forming rotor and control the pitch of the wire turns of the coil. A disc brake system is mounted on the roll support shaft for breaking the rotation of the wire supply rolls to control the tension in the wires, and the roll support shaft is pivotable in a horizontal direction to facilitate loading of new wire supply rolls into the machine. The machine is also adapted to be used with only one wire supply roll when only a single helix nonrotating continuous coil is required.
