Abstract
An opening roller for an open-end spinning device is provided with a fitting of combing teeth. The fitting comprises zones with reduced, or entirely without, combing-out effect. The zones with reduced or entirely without combing-out effect are so designed and arranged relative to the combing teeth on the fitting that the fibers are combed out evenly of the sliver. A careful treatment of the fibers without a variation in yarn evenness is hereby achieved.
