Abstract
This invention provides a rotor sealing device used on an open-end spinning apparatus having a spinning rotor which forms therein air-discharge apertures, the opening in said spinning rotor being openably closed by a body member which has a fibers delivery aperture formed therein; said rotor sealing device being characterized in that a sealing member is inserted into the space located between said rotor opening and said body member positioned in opposite relation thereto. This device, though being of such a simple construction, is capable of improving the effect of rotor inside sealing over devices heretofore.
