Abstract
In an open end spinning unit having a stationary frame member and a spinning rotor rotatably supported by the frame member, and in which, during operation of the unit, a flow of gas occurs from the yarn removal opening and fiber inlet opening of the unit to a gas extraction opening thereof, the gas traversing a path surrounding the rotor, a gas flow controlling structure is disposed around the rotor to define a narrow gap with the exterior surface of a portion of the rotor, so that the space adjacent the remainder of the rotor is in communication with the gas flow path only via the narrow gap.
Claims5
In an open end spinning unit having a stationary frame member presenting a yarn opening, a fiber inlet opening and a gas extraction opening, and a spinning rotor rotatably supported by the frame member and enclosed by the frame member, the stationary frame member and the spinning rotor together defining a gas flow space via which gas flows from the yarn removal opening and the fiber inlet opening to the gas extraction opening during operation of the spinning unit, and further defining an annular space coextensive with a portion of the axial extent of the rotor, the improvement comprising gas flow controlling means fixed relative to said frame member, surrounding at least a portion of said rotor and defining a narrow gap with the outer surface of said rotor which provides the only communication between said gas flow space and said annular space for substantially eliminating the flow of gas streams into said annular space.
