To provide a bobbin frame having large output density, allowing use of a relatively small and lighter driving device and maintaining a guarantee for sufficiently high stability of the driving device by arranging the driving device incorporated into the bobbin frame, applying a load to an electric motor of the driving device by a braking current for braking a twill winding bobbin, and improving the form of forming the braking moment in the inverse direction of a rated current by the braking current in the bobbin frame for a fiber machine for manufacturing the twill winding bobbin.

A cooling medium circulating passage 36 capable of deriving motor heat of the electric motor 35 is arranged inside the bobbin frame 18.
