Abstract
1,146,480. Yarn false twists. MONSANTO CO. 17 June, 1966 [23 June, 1965], No. 27269/66. Heading D1D. A pneumatic false twisting device particularly for false twisting continuous filament which is subsequently formed into a non- woven structure comprises a tube 10 containing a tube 14 having on its outer surface a fin or rib 18 in screw-thread configuration an air inlet 24 being provided in tube 10 such that air is guided by the fin or rib 18 into a spiral path to false twist the filament passing through the 'bore of tube 14. The suction created at the lower end of tube 14 by the air draws the filament through the tube. The amount of false twist and the force applied to the yarn is regulated by changing the air flow or by changing the surface of tube 14 and its relationship with wall 20. In Fig. 3, not shown, the fins (36, 37) are of opposed pitch and the air is blown in at the midpoint of the device to travel outwardly in opposed spiral paths. The outer edge of the has engages the inner surface of tube 30. The filament is forwarded by roller means.
