Abstract
An inline winder is provided for taking-up a rapidly advancing filament, especially a glassy alloy filament of indefinite length at constant speed directly from a high speed continuous forming process without tension isolation. The winder is inherently load-following and thus eliminates the need for any complex feedback control system. The winder comprises a winding reel rotatively driven by a synchronous-hysteresis electrical motor and selection means for independently adjusting voltage and frequency input to the motor. The method of using the winder comprises preadjusting the frequency input to initially synchronize winder and filament speeds and preadjusting voltage input to select winding torque and initial winding tension. A transfer device is also disclosed wherein winding is transferred uninterruptedly from a wound, rotating reel to an empty, rotating wheel.
