reference however instead of brushes the air separator of the present invention utilizes a series of axially aligned channels 17 bearing substantially radially extending teeth 18 which pass near the cylindrical housing and combing cylinder 101 the surface of the high speed air separator creel 104 may be described as having peripherally equally spaced apart substantially axial rows of sharp teeth completely surrounding it the details of these teeth should further be described as axial channel saws whose legs project substantially radially outward or slightly forward leaning in the direction of rotation as shown in fig4 a and 4b cleaning cylinder 103 generally rotates in a clockwise direction such that the surface of cleaning cylinder 103 and combing cylinder 101 travel in the same direction at their closest point of approach all of the fiber passing through the machine must pass between cylinders 101 and 103 in this region referring to fig3 note that the size of the teeth 105 are exaggerated to show their profile the fine teeth 105 on the combing cylinder are aggressive when converging towards the cleaning cylinder 103 but are not aggressive when diverging therefrom that is to say the narrow sharp pointed closely or densely spaced uniquely shaped teeth on the combing cylinder 101 comb against the aggressive teeth of the cleaning cylinder 103 as their surfaces converge but yield substantially all the fibers to the aggressive cleaning cylinder 103 as their surfaces diverge in normal combing operation the slowly turning combing cylinder 101 only holds a small percentage of the incoming tufts letting the bulk of the tufts.
