PURPOSE:To improve the quality of package when winding a square end package with the speed higher than 4,500m/min. by varying the traversing speed with specific pattern in accordance to the winding time. CONSTITUTION:When winding a square end package with the speed higher than 4,500m/min. while traversing the string 1 to a bobbin 3, the traversing speed is varied gradually in the range of pattern angle of 3 deg.-10 deg. in accordance to the winding time of package to wind such that the variation pattern in the plane employing the winding time on the abscissa while the traverse speed on the ordinate will be repetition at least one time of second power distribution curve. The pattern angle is the angle to be made by the pattern 2 of string 1 and the line perpendicular with the longitudinal direction of the bobbin 3. Consequently the package quality under high speed winding can be improved. |
