Abstract

1386679 Rotating spinneret COAL INDUSTRY (PATENTS) Ltd 1 June 1973 [2 June 1972] 25915/72 Heading B5B [Also in Division C1] Filaments, particularly filaments of pitch, are extruded through a spinneret so rotating that the filaments are twisted together to form a yarn. Spinneret tube 1 is closed at the bottom by plate 2 containing a plurality of orifices 3 parallel to the axis of the tube. Heater 9 heats the material 8 to be spun. Tube 1 is rotated by means of belt 5 acting on wheel 4. Gas pressure, to assist in the extrusion, is provided by connecting inlet 7 to a source of a suitable gas, for instance nitrogen.
