Abstract:
A spinning machine comprising a draft device, a nozzle member having a hollow interior and containing a compressed air injector for producing a whirling air flow on a fiber bundle supplied from said draft device to produce spun yarn, and a spindle member including a a spindle having a yarn path formed therein though which said spun yarn is conducted, wherein a fiber bundle inlet of the yarn path in said spindle is diagnosed within the interior of said nozzle member in concentrically spaced relation thereto to define a passage for the discharge of air from the interior of said nozzle member, said spindle containing a spun yarn outlet having a smaller inner diameter than that of said spun yarn inlet, and said spindle member containing a rearward end spaced from said spun yarn outlet of said spindle for receiving spun yarn to be conducted through said spun yarn outlet of said spindle to the fiber bundle inlet thereof for piecing in said nozzle interior, an air supply hole for injecting air to induce an air flow into the rearward end of said spindle member for conducting said spun yarn for piecing,said spindle member containing a discharge region formed in an intermediate part of said yarn path between said rearward end and said spun yarn outlet of said spindle, said discharge region containing means for discharging from said yarn path to the exterior of said spindle member some of the air injected by said air supply hole.
