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.

A yarn producing apparatus produces CNT (carbon nanotube) yarn from CNT fibers while causing the CNT fibers to run. The yarn producing apparatus includes an aggregating unit that aggregates the CNT fibers, and a twisting and winding device that twists the CNT fibers aggregated by the aggregating unit. The aggregating unit includes an adjusting mechanism that adjusts the aggregation state of the CNT fibers.
