Abstract

An open-end rotor spinning apparatus is provided which includes a spinning rotor element for forming yarn including an open side. A cover element is provided for covering the open side of the spinning rotor element. A projection element is disposed at the cover element and projects into the side of the spinning rotor element. A fiber feeding duct is disposed in the projection element. A yarn withdrawal duct is also disposed in the projection element and provides a pathway for formed yarn being withdrawn from the spinning rotor element. A yarn withdrawal nozzle element projects from the yarn withdrawal duct element into the spinning rotor element open side. Holding elements are provided other than the yarn withdrawal duct element which hold the yarn withdrawal nozzle element on the projection element.
