Open-end spinning machine

Abstract

Open-end spinning unit having two housings connected to each other, a first housing containing a spinning rotor adapted to be supplied through a supply duct with separated fibers carried by an air stream while yarn is withdrawn therefrom through a take-off duct, the second housing containing a sliver supply roller and a combing-out cylinder followed by said fiber supply duct extending through a lid inserted into the spinning rotor and forming a part of said second housing, the spinning rotor being surrounded with an air collecting space adapted to collect the air to be withdrawn from the spinning rotor. The spinning rotor turns about a vertical axis of rotation and is driven by an individual motor through the axis of which the yarn take-off duct extends in an upward direction. The lower front part of the spinning rotor extends into a cavity provided in the top part of said second housing. The combing-out cylinder and the sliver supply roller have horizontal axes of rotation perpendicular to the longitudinal axis of the open-end spinning machine. The top of said cavity is covered by said first housing while the cavity forms said air collecting space, a central part of the bottom of said cavity being formed by said lid.
