Claims
- 1. A system for forming a wire pack including plurality of wires of equal predetermined length extending between spaced wire supports, said system comprising:
- a cylindrical roll mounted for rotation about an axis;
- means spaced from said roll for supporting a source of wire to be wrapped around the exterior of said roll and exerting thereon a force in a direction away from said roll;
- a guide intermediate said source and said roll for locating wire from said source relative to said roll;
- a pair of said wire supports arranged to be mounted on said roll in respective positions adjacent but circumferentially spaced from each other and extending axially of said roll in position for engaging wire wrapped around said roll; and
- means for engaging wire wrapped around said roll and positioning adjacent turns at regular intervals relative to each other,
- said roll including an axially-extending recess in the periphery thereof, and said supports being adapted to be mounted in said recess.
- 2. The system of claim 1 wherein each of said supports includes a base adapted to be mounted in said recess with the upper surface of said base substantially aligned with the intersection of the exterior surface of said roll with said side.
- 3. The system of claim 1 including means for translating said roll axially relative to said guide during rotation of said roll to maintain the path of wire from said guide to said roll substantially constant.
- 4. The system of claim 3 wherein said means for translating moves said roll axially a distance equal to a said regular interval per complete rotation of said roll.
- 5. The system of claim 1 wherein said means for supporting comprises a shaft for receiving a spool of wire, a drive for rotating said shaft, and a slip clutch assembly for permitting said spool to rotate relative to said shaft in a direction opposite the direction of rotation of said shaft while exerting on said spool a force tending to rotate said spool with said shaft.
- 6. The system of claim 1 wherein said means for engaging includes a plurality of regularly spaced recesses in the surface of said roll arranged spirally on the roll to receive and locate respective turns of said wire.
- 7. The system of claim 6 wherein the exterior of said roll is threaded, and said recesses comprise said threads.
- 8. The system of claim 7 wherein the pitch of said threads is less than about 0.02 in.
- 9. The system of claim 1 including means for locating said supports axially relative to said roll and fixing clamps onto said supports relative to said roll.
- 10. The system of claim 1 wherein said roll is cylindrical.
- 11. A system for forming a wire pack including plurality of wires of predetermined length, said system comprising:
- a roll mounted for rotation about an axis;
- means spaced from said roll for supporting a source of wire to be wrapped around the exterior of said roll and exerting thereon a force in a direction away from said roll;
- a pair of wire supports arranged to be mounted in respective positions spaced from each other and extending axially of said roll in position to engage wire wrapped around said roll; and;
- means for engaging wire wrapped around said roll and positioning adjacent turns at regular intervals relative to each other;
- said roll including an axially-extending recess in the periphery thereof,
- said supports being adapted to be mounted in said recess,
- each of said supports including a base adapted to be mounted in said recess with the upper surface of said base substantially aligned with the intersection of the exterior surface of said roll with said side, and
- each of said supports including a cover adapted to overlie the base thereof and means for attaching the cover and base thereof together tightly to clamp turns of wire therebetween.
- 12. The system of claim 11 wherein each of said bases is longer than the cover therefor, and each of said supports includes a first set of fasteners for attaching the cover thereof to the base thereof in a position leaving the opposite ends of the base thereof uncovered and a seecond set of fasteners extending through the exposed ends of the base thereof for securing the support to said roll.
