Abstract
The fiber collecting groove is located at the largest inside diameter of the rotor and is formed by two surfaces which define an angle of aperture .alpha. from 45.degree. to 90.degree.. The bottom of the groove is of a radius of from 0.1 to 0.5 millimeters. Also, the bisector of the angle of aperture .alpha. forms an angle .beta. with the plane of rotation of the groove of a value from 0.degree. to 45.degree. while the yarn take-off direction forms an angle with the plane of rotation of from 0.degree. to 25.degree.. Trash accumulations are reduced to a minimum without detrimentally effecting yarn quality.
