Abstract: A payout tube for insertion in a radial hole of a wound coil of filamentary material and extending from the inner to the outer wind of the wound coil, the payout tube having entrance and exit openings in coaxial and spaced relationship with one another. The size of the entrance opening is determined by the following equation: Yc=3.5 sin×/Dm, where Dm is the diameter of the mandrel, X is the length along the circumference of the wind and Yc is the coil pattern. Yc′=3.5/Dm Cos×/Dm at x=0; Yc′=3.5/Dm, and the slope H of the coil pattern=Tan−1[3.5/Dm]=23.629 degrees. The length L of the payout hole is determined as: L=O×Dm×pie/360 degrees; where O is the payout hole opening; the width of the payout hole is W=L cos(H).
