摘要： A method of and an apparatus for pneumatically removing a fibrous ribbon or a severed yarn end from the spinning rotor of an open-end spinning machine in the event of an interruption in the spinning process having the steps of withdrawing the fibrous ribbon or severed yarn end from the spinning rotor by directing a first pressure air stream against the mouth of an air withdrawing duct, and scavenging the spinning rotor by directing a second pressure air stream against a collecting channel of the spinning rotor in order to remove any severed fibers and impurities.

摘要： Method of and apparatus for cooling the spinning units of open-end spinning machines driven by individual high speed electric motors. A cooling air flow is separated from the technological air flow, such cooling air flow being introduced into the housing of each unit in the space between the rotor of its motor and the spinning rotor connected thereto and dividing into two flows. One such flow travels between the stator and rotor of the motor; the other flow travels within the unit housing radially outwardly of the stator of the motor.
