Abstract

1289683 Spinning yarns IMPERIAL CHEMICAL INDUSTRIES Ltd 23 Oct 1969 [8 Nov 1968 20 May 1969] 53061/68 and 25628/69 Headings DID and D1F A yarn is formed by drafting and spinning with the twist being prevented from running back to the drafting stage by passing it through a further stage in which it is subjected to zero draft and is "wholly supported" during its travel therethrough. The term "wholly supported" includes supporting the roving so that it is bridging a gap which is less than the effective staple length of the majority of fibres in the roving. As shown, a roving is drafted in two stages at x and y and is fed without draft around the surface of roller 6 to emerge from the nip between rollers 6 and 7. The roving is then twisted on a ring and traveller. The nip prevents the twist running back to the drafting stages. In alternative embodiments, the further stage is formed between two pairs of closely spaced rollers, (Fig. 2), or between aprons (Fig. 3).
