1,152,682. Finishing and guiding yarns. DEERING MILLIKEN RESEARCH CORP. 28 Dec., 1965 [28 Dec., 1964], No. 17476/68. Divided out of 1,152,681. Headings DID and D1F. In apparatus for simulating false-twisting, heating and finally separating two thermoplastic yarns initially supplied in adjacent side-by-side relationship e.g. as described in the parent Specification, the angle of separation of the yarn is a function of, and varies inversely as, the length of the yarn path between the false-twisting and separating means: the provision of yarn guide pulleys on an adjustably movable arm or of an adjustable guide bar Figs. 13 and 14 (not shown) therefore enables a selective determination of such angle. |
