Open-end fiber veil spinning apparatus and method

摘要

In a process for open-end spinning at least one sliver is opened to single fibers, which form a fiber veil. The single fibers are fed to a rotating collecting surface which is driven transversely to their travel direction, and are withdrawn from the collecting surface in the form of a yarn with twist along a yarn formation line before the completion of one single revolution of the collecting surface. The single fibers are never slowed down at any point in the sliver-to-yarn process. Immediately after their separation from the sliver, the single fibers are subjected to an exactly predetermined, mechanically controlled speed.
