A flyer assembly including a spindle rotatable about an axis of rotation, an arm coupled to the spindle, a level wind device axially mounted to the arm, a first friction member disposed along a width of the level wind device and shaped into a convex curve defining the width of the level wind device, a second friction member offset from the first friction member, and a fulcrum having an eye or hook.

A flyer for spinning a fibrous roving onto a bobbin includes a housing defines a central hole passing therethrough. A center rod, supporting the bobbin, is rotated by a spinning system. A battery is contained in the flyer and powers an electric motor. A hollow level wind frame is affixed to the housing and defines an elongated slot passing therethrough. A level wind gear in the level wind frame is rotated by the electric motor. A level wind carriage system is driven by the level wind gear and oscillates repeatedly between a first end and a second end as the level wind gear is rotated, and includes a pawl engaged with the level wind gear. A guide is coupled to the pawl and passes through the elongated slot defined by the level wind frame. The fibrous roving passes through the guide.
