Start spinning arrangement for an open end friction spinning machine |
摘要 |
A process and apparatus is disclosed for improving the start-spinning of yarn on an open end friction spinning machine. To facilitate an exact alignment of the return yarn end to be pieced up with newly supplied incoming fibers, the respective spinning units are provided with a moveable cover part which in the open position exposes the yarn forming wedge slot between the friction rollers. Devices are provided for returning the yarn end and holding the same at a slight spacing from the friction rollers at the wedge slot and for sequentially timing the yarn draw off during start spinning with the activation of the fiber feed and the suction air flow related thereto.
