Abstract

986,245. Spinning yarns; twist-tubes. BRITISH NYLON SPINNERS Ltd. March 9, 1964 [March 22, 1963], No. 11379/63. Headings DID and D1F. In a process for imparting varying twist to a monofilament or multifilament or staple fibre yarn, the yarn is linearly advanced across and makes intermittent frictional i.e. rolling engagement with at least one twisting or rolling surface moving across the line of travel of the yarn. The process may be applied to yarn e.g. of nylon, immediately after it has been drawn and submitted to a heat relaxing treatment. The final twist in the yarn may alternate in S and Z directions or it may be unidirectional i.e. varying in value above and below a mean twist, and it ensures coherence of filaments during subsequent processes such as warping, winding, sizing, weaving, knitting or braiding. In the alternate-twisting apparatuses shown in Figs. 1-3, a running yarn Y is moved by a reciprocating guide 7, a rocking member 13 with guides 15,17 and 19, and swinging member 21 with guides 23 and 25, so as to contact alternately the opposed (twisting) surfaces of crossed sections of a travelling band 1, the oppositely moving peripheral surfaces of laterally off-set twist tubes 9 and 11, and opposite sides of the peripheral surface of each end of a twist tube 9. In the apparatuses of Figs. 4 and 5, a running yarn Y is moved by reciprocating guides 7 into and out of frictional engagement by one face of a travelling endless band 1. Specification 797,051 is referred to.
