Abstract
Method and apparatus for winding filamentary on a mandrel rotatable about a spindle axis of rotation and a traverse reciprocating with respect to the mandrel to wind the filamentary material in a figure 8 coil configuration with a payout hole extending radially from the inner to the outer wind of the coil; controlling the rotation of the mandrel about the spindle axis of rotation; controlling the reciprocating movement of the traverse with respect to the rotation of the mandrel to wind the filamentary material on the mandrel in the coil of a figure 8 configuration to form the radial payout hole having a substantially constant diameter.
Claims16
Apparatus for winding filamentary material, comprising:
- a mandrel rotatable about a spindle axis of rotation and a traverse reciprocating at a fixed distance with respect to said spindle axis to wind said filamentary material in a figure 8 coil configuration with a payout hole extending radially from the inner to the outer wind of said coil;
- means for controlling the rotation of said mandrel about said spindle axis of rotation;
- and
- means for controlling the reciprocating movement of said traverse with respect to the rotation of said mandrel to wind said filamentary material on said mandrel in said coil of a figure 8 configuration to form said radial payout hole having a substantially constant diameter.
