ABSTRACT:
A method and apparatus is provided for treating the surfaces of a pair of rollers used in an open-end friction spinning unit containing a pair of friction rollers arranged in an operational position to form a wedge-shaped yarn-forming gap. The pair of friction rollers is treated prior to installation in a spinning unit by rotatably mounting the two friction rollers adjacent one another outside the spinning unit, causing the friction rollers to rotate on their longitudinal axes and simultaneously treating the surface of each friction roller with common treating element.
