Abstract

Apparatus for open-end spinning of discrete fibers in a narrow gap between adjacent, air permeable surfaces of two tapered drums whose axes of revolution are at an acute angle and which rotate in the same direction, while drawing air through said surfaces along said gap, said tapered surfaces being frusto-conical or being a segment of a hyperboloid of revolution, and fiber feed means having a channel with an elongated, narrow mouth extending along said gap.
