Measures for influencing the axial airflow in the spinning channel of a vortex spinning apparatus

摘要

In a textile spinning process a feed flow (28) of loose individual fibres (F) is drawn into a stationary spindle (27) passage and twisted to yarn, prior to emerging via a passage. The flow of air is esp. regulated and dosed such that no fluid escapes from the spindle passage inlet rim. The spindle passage and effluent air passage are linked such that fluid does not emerge from the spindle inlet to the effluent air passage. The balanced effect is achieved either by bleeding air from or admitting supplementary air into the spindle passage via link passages (40) between the spindle passage and air discharge passage. Also claimed is a commensurate spinning assembly.
