The total height (H) is 2 to 3.5 mm, preferably 2.5 mm and the depth of the tooth undercut 1.1 to 1.7 mm, preferably 1.4 mm. The angle of the leading edge of the tooth is 5 to 24 [deg], preferably 10 [deg]. Two or three taker-in rollers of the same diameter can be employed with successive rollers having increasing leading angle, point density, tooth height, and/or speed.
