Abstract

A spinning assembly for a wrapped yarn spinning machine in which a staple sliver is guided by a delivery device into a hollow spindle which carries a co-rotating binding thread; the thread is wound around the staple sliver by the rotation of the hollow spindle. A stationary balloon limiter is provided in the vicinity of the binding thread and a screen is mounted in front of the delivery device, which screen comprises a passage for the staple sliver. This screen is constructed as a screen plate, mounted at an axial distance from the balloon limiter. This construction of the present invention has the advantage that an air stream is generated within the balloon limiter, which flows upward from below and leaves radially through the gap between the upper end of the uncovered balloon limiter and the screen plate. This air stream is directed counter to both the sliver and the binding thread entering the hollow spindle, so that no fiber fly can penetrate the interior of the hollow spindle.
