    Winders have a center roll (a bobbin, spool, reel, belt-winding shell, etc.) on which the material is wound up. Often there are metal bars that travel through the center of the roll and are shaped according to their intended purpose. A circular bar facilitates greater speed, while a square bar provides a greater potential for torque.
