ABSTRACT:
An open end spinning method includes the step of providing a spinning chamber with an annular slip wall. A sliver of fiber material is placed onto the annular slip wall that widens continuously in the direction of sliver introduction into the spinning chamber. The angle of the annular slip wall to a rotational axis of the spinning chamber is between 8.degree. and 12.degree.. A yarn is formed from the fiber material in the yarn formation zone which is located within the portion of the annular slip wall upstream of a widest diameter of the annular slip wall viewed in the direction of sliver introduction. The fiber material is removed as a yarn from the spinning chamber through a yarn removal channel, extending along the rotational axis of the spinning chamber, in the direction opposite the direction of sliver introduction.
