Abstract
An opening or beater roller for open-end spinning machines, in which a cylindrical roller has a sawtooth wire wound helically onto its outer surface. The arrangement is such that a base region is widened in relation to the teeth. Base regions of adjacent turns of sawtooth wire are separated by a gap from one another, and the ratio of the height to the width of the base region is less than one.
