ABSTRACT:
A winder is provided for winding synthetic filament into packages formed on a rotatable chuck which is directly driven by a drive motor. The speed of the drive motor, as represented by a suitable signal, is compared with a limit therefore, as represented by a second signal. The limit speed is reduced during formation of a package as an inverse function of the package diameter.
