摘要：
To improve the re-piecing operation, especially in terms of its success rate, at high spinning speeds, the free thread end cut to the length of a piecable end and retained after cutting the length is exposed to a turbulent air flow which causes it to execute whiplash-like oscillations. The surface of the thread end is thereby roughened. The thread end prepared in this way is subsequently transferred to the fiber-collecting surface of the open-end spinning apparatus. The roughening of the surface of the free thread end is accelerated when the end is whipped against an edge-like projection or a rough surface.
