Arrangement for open-end friction spinning |
摘要 |
An open-end friction spinning arrangement is disclosed with two adjacently arranged rollers driven in the same rotational direction in forming a wedge-shaped year forming gap with their cover surfaces. It is provided that a suction device generates an air current directed into the wedge-shaped gap. This suction device creates differential suction forces at different zones of the wedge-shaped gap. The suction device includes different length suction slots in the respective friction rollers. An air inlet device having varying cross-sections along the length of the yarn forming gap is provided to optimize the effect of the slots and the air inlet opening in the forming yarn.
