Abstract

1,178,397. False twisting. IMPERIAL CHEMICAL INDUSTRIES Ltd. 19 July, 1967 [29 July, 1966], No. 34231/66. Heading D1D. Filament yarns or tows 14 are false twisted by engagement with a rotating spiral surface 10, with the points of contact between the surface and the yarn or tow moving along at substantially the same speed as the yarn or tow. The diameter of the spiral surface may decrease outwardly from the centre as shown or be of constant size. A roller may press the yarn or tow against the spiral surface.
