Abstract: 361,373. Twisting-apparatus for the production of fancy yarns. DUNLOP COTTON MILLS, Ltd., 32, Osnaburgh Street, London, ANDREW, T. E. and LANGSTRETH, M., of Dunlop Cotton Mills, Rochdale. Aug. 14, 1930, No. 24326. [Class 120 (ii).] A machine for twisting filaments of the kind in which two twists can be imparted for every revolution of the twisting spindle, by forming the filament into a loop and rotating one leg round the other, the spindle being apertured both lengthwise and sidewise, is adapted so that it may produce fancy yarns, covered yarns or covered wire, cable or other core, the component filaments in all instances lying irregularly, differentially or asymmetrically to each other. In the form shown in Fig. 1, the thread 2 passes from a bobbin 3 through the spindle 1 and is wound by a rotating disc in the usual way round a thread 4 drawn from a bobbin 5. In the apparatus shown in Fig. 2, a thread 2 passes through the longitudinal hole of the spindle and a thread 4, rotated by a disc passes in through the lateral hole and is wound round the first thread.. In this form, though the machine is of the double-twist type, only one twist per revolution is imparted. In the form shown in Fig. 3, threads 2, 4, from packages 3, 5, pass around spindles 14, 15 on gears 12, 13, the thread 2 passing through spindle 1 and being wound by a disc upon the thread 4. In this case one filament drives the other, the nature of the drive being determined by the relative sizes of the gears 12, 13 and spindles 14, 15. Spur gearing, friction gearing, and elliptic gearing may be employed. Fancy effects are produced by varying the speed of the filaments or by other suitable means. Specifications 338,570 and 338,606, [both in Class 120 (ii), Spinning, twisting &c.], are referred to.
