Abstract:
A payout tube for insertion in a radial hole of a wound coil of filamentary material and said radial hole extending from the inner to the outer wind of said wound coil, said payout tube comprising:an entrance and an exit opening in coaxial and spaced relationship with one another: the size of said entrance opening is determined by the following: Yc=3.5 sin x/Dm where Dm is a diameter of the mandrel on which the coil of filamentary material is wound, x is the length along the circumference of the wind and Yc is the substantially sinusoidal FIG. 8 coil pattern;Ycâ€²=3.5 Dm Cos x/Dm At x=0; Ycâ€²=3.5/Dm; and the slope H of the coil pattern =Tanâˆ’1 [3.5/Dm]=23.629 degrees;the length L of the opening is determined as: L=PTO x Dm x pi/360 degrees; where PTO is the size of the entrance opening in degrees;the width of the payout tube is W=L Cos (H); the size of the exit opening is determined as being a fixed amount of degrees less than the entrance opening; and a flange member surrounding the exit opening for engaging a panel of a container retaining the wound coil.
