Abstract

A friction spinning unit employs two rotatable bodies to define the spinning gap, at least one of the bodies being in the form of a cone whose surface moves towards the friction spinning gap from the same side as that from which separated fibres are fed by a fibre feed means. This configuration of the bodies generates a self-conveying action which propels the bundle of fibres axially along the friction spinning gap so that the bundle itself enters twist-blocking means which facilitates the piecing action and dispenses with the need for a seed yarn to be returned to the friction spinning gap to piece up after a yarn break or after shutdown.
