Title: Automatic spinning method for spun yarn of good quality and apparatus thereof
Inventor: NEGISHI EIZABUROU
IPC: D01H4/10
Filed: 1981-03-11
Abstract: PURPOSE:An apparatus, containing an outer rotor and an inner rotor, rotating differentially, and having a generating means for an air vortex, and designed to prepare thick spun yarns of high tenacity by forming a sliver collected in the outer rotor into a yarn with the air vortex. CONSTITUTION:An outer rotor 8 is rotated by a running belt 19, and a pulley 16 is simultaneously rotated at a little higher speed differentially to rotate an inner rotor 9 differentially. The internal air is thinned by the rotation of the outer rotor 8, and a fibrous group (F) is sucked from a feed means 1 and discharged to the disc surface (9b) of the outer rotor 9. The fibrous group (F) is then separated into single fibers (F1), which are received on the inner wall surface (8a) of the outer rotor 8 and collected to give a sliver (F2). On the other hand, compressed air fed from a feed pipe 20 into a hollow rotating shaft 15 forms an air vortex in a spinning chamber 10. Thus, the free ends of the respective fibers of the collected sliver (F2) are oriented in the central direction of a yarn to give the aimed spun yarn of high tenacity.
