Abstract
An open-end spinning aggregate with a housing connected to a vacuum source, in which is arranged a spinning rotor provided with an open end-face, into which projects an insert leaving an annular gap and containing a central filament removal channel as well as a fiber feed channel whose orifice is disposed opposite a fiber-collecting surface of the spinning rotor which extends from the open end-face up to a fiber-collecting groove occupying the area of the largest diameter of the spinning rotor; ventilating bores are provided in the wall surface opposite the fiber-collecting surface with respect to the fiber-collecting groove whose axes extend at least approximately parallel to the axis of rotation of the spinning rotor.
