Abstract
An apparatus for winding filamentary material includes a mandrel rotatable about a spindle axis of rotation and a traverse reciprocating at a distance with respect to the spindle axis to wind the filamentary material in a figure-eight coil configuration with a payout hole extending radially from the inner to the outer wind of the coil. The apparatus includes a measurement device for measuring the diameter of the coil as it is being wound around the mandrel, and a controller for controlling the reciprocating movement of the traverse with respect to the rotation of the mandrel based on the measured diameter of the coil. The measurement device may include a first sensor configured to measure a length of filamentary material wound about the mandrel and a second sensor configured to measure an angular displacement of said mandrel during the winding of the length of filamentary material about said mandrel.
