  • Each set of casting rollers 76 is arranged to curl or deform the corresponding wire 16 beyond its elastic limit to form a turn 18 around the mandrel 45.
  • the wire turns 18 have substantially no stress so that upon subsequent removal from the mandrel, the coil 15 will maintain its shape.

  • the interchangement of different diameter feed wheels 72 and change gears 85 provides for precisely controlling the feed of the wires 16 and for producing coils of different diameters and pitches.
  • the coil forming rotor 50 is driven by a variable speed electric motor 90 (FIG. 1) which has a shaft 91 connected by a pulley 92 and an endless flexible gear belt 93 to a pulley 94 (FIGS. 1 and 6) secured to the cylindrical hub 57 of the rotor 50.
  • An idler pulley 96 maintains a predetermined tension in the gear belt 93.
  • the double wire nonrotating helical coil is continuously produced or formed on the stationary mandrel 45 by rotation of the rotor 50 in the direction indicated by the arrow in FIG. 1. That is, after the supply rolls R of wire are mounted on the stationary support shaft 28,
  • the wires 16 are directed from the supply rolls R around the corresponding guide rollers 64 to the corresponding wire feed units 70.

  • the pull on the wires 16 causes the wire supply rolls to rotate on the shaft 28 at a speed or rate which is slightly greater than the rotational speed or rate of the rotor 50.
  • This additional rotational speed of the wire supply rolls R is due to the fact that with each revolution of the rotor 50, a length of wire 16 corresponding to the length of a helical turn 18, is unwound or pulled from each of the supply rolls R.'The tension in the wires 16 from the supply rolls R tothe wire feed wheels 72 is controlled by actuation of the brake cylinder 38.

  • the speed of the belts 102 is adjusted to change the pitch of the wire turns 18 of the nonrotating helical coil 15 as it is being produced by rotation of the rotor 50.
  • a change in the speed of the motor to increase or decrease the speed of forming the helical coil 15 automatically changes the speed of the coil feed belts 102 so that the preselected pitch of the wire turns 18 remains constant.
  • a helical coil forming machine constructed in accordance with the present invention, provides desirable features and advantages.
  • the machine provides for continuously and rapidly producing a multiple wire nonrotating helical coil from large supply rolls.
  • the machine is also adapted for producing a single wire helical coil, simply by feeding only one wire 16 into the rotor 50 and between one set of casting rollers 76.
