Abstract
The present invention is drawn to fiber cleaning utilizing an alternating series of cleaning saw cylinders and doffing brush cylinders. The doffing brush cylinders transfer ginned fiber from an upstream cleaning saw cylinder to the next downstream cleaning saw cylinder in such a way that the flow of the fiber changes direction at the pinch point between the downstream cleaning saw cylinder and the doffing brush cylinder. Guiding means including control bars are provided to help guide the ginned fiber from the doffing brush cylinder to the next downstream cleaning saw cylinder at the pinch point. Flow deflecting means including air control bars are provided to deflect a substantial portion of the flow of entrained air from flowing around the doffing brush cylinder.
