    • A rotor type open-end spinning unit in which in order to prevent blowing of air to the rear of an outlet of a fiber transporting channel formed in a spinning body and impingement of an air stream from the fiber transporting channel against the back face of a separator, the rear end of the outlet of the fiber transporting channel on the central side of a rotor is expanded forward of an imaginary line, connected between the rear end of the channel outlet furthest from the center of the rotor and the center of the rotor, and the angle .alpha. between the face of the fiber transporting channel confronting the combing roller and the plane intersecting the axis of the rotor at a right angle is made substantially equal to the taper angle .theta. of the back face of the separator.
    • 一种转子式开口纺纱单元,其中为了防止空气吹送到形成在纺纱机中的纤维传送通道的出口的后部,并且将空气流从纤维传送通道撞击到纺纱机的背面 分离器,转子中心侧的纤维传送通道出口的后端在假想线前方扩展,连接在离转子中心最远的通道出口的后端与转子中心之间 并且使与梳理辊相对的纤维传送通道的表面与与转子的轴线成直角相交的平面之间的角度α基本上等于分离器背面的锥角θ。

    • A spinning unit of an open-end spinning machine is disclosed which comprises a rotor having an inner wall, a bottom portion and an open end opposite to said bottom portion and arranged to rotate about a center axis perpendicular to said bottom portion; and a stationary closing member projecting into a spinning chamber of said rotor to thereby close the open end of said rotor and provided with a fiber supply duct which opens toward the inner wall of the rotor, and a yarn guide hole which opens in an end surface thereof opposite to the bottom portion of the rotor. The fiber supply duct is arranged in the closing member so that an inner wall of the fiber supply duct located on a side of the rotational center of the rotor is extended to be near to the rotational center of the rotor or to be over the rotational center of the rotor. The width of the fiber supply duct is established to be not larger than 90 percent of the diameter of the closing member.
    • 公开了一种开口纺纱机的纺纱单元,其包括具有内壁,底部和与所述底部相对的开口端的转子,并且布置成围绕垂直于所述底部的中心轴旋转; 以及固定的关闭构件,其突出到所述转子的旋转室中,从而封闭所述转子的开口端,并设置有朝向所述转子的内壁开口的纤维供给管,以及在所述转子的内表面开口的导纱孔 其与转子的底部相对。 纤维供给管配置在封闭部件中,使得位于转子的旋转中心侧的纤维供给管的内壁延伸到靠近转子的旋转中心或者在转动中心附近 的转子。 纤维供应管道的宽度被确定为不大于封闭件直径的90%。
