DISCHARGE CONTROL IN CENTRIFUGAL SPINNING APPARATUS OF MOLTEN PITCH AND APPARATUS THEREFOR

摘要

PURPOSE:To suppress bad influence of turbulent air generated around a disk and in the bottom part, fly spun yarns away and carry out drawing, by providing a gas jetting apparatus for blowing the spun yarns in a spinner disk for centrifugal spinning. CONSTITUTION:Air jetting ducts are provided on both upper and lower sides of a spinner disk 6 for centrifugal spinning having many orifices on the peripheral surface and guides for enveloping and jetting discharged fibers in gas streams in the discharge direction from both upper and lower sides of pitch fibers discharged through an orifice 8 are provided from the end parts of the ducts to the outside of the orifice 8.
