Abstract
1,236,458. Draw twisting yarn. MASCHINENFABRIK RIETER A.G. 5 June, 1968 [5 June, 1967], No. 26745/68. Heading D1D. In a method of draw-twisting, the winding spindle and delivery mechanism are accelerated to production speeds in such a way that the ratio of spindle speed to delivery mechanism speed decreases. The ratio is reduced from a critical value corresponding to a critical number of turns per length in the yarn. The delivery mechanism is so accelerated over a period of the starting time that the yarn waste is reduced as compared with a method in which both production speeds are gained uniformly over the same time period. As shown in Fig. 4 the thread delivery speed VL and spindle speed Ns both increase over the period Ao such that VL/Ns is constant. After remaining constant till t 3 before NS/VL reaches the critical value K the delivery speed is again increased. After running at production speeds the apparatus is stopped in the reverse sequence. Comparative indications of wastage in prior out processes and the process of the invention are given in Figs. 2d, 4d respectively. In a modification (Fig. 6 not shown) the delivery mechanism may accelerate slowly before the ratio NS/VL is reduced. The apparatus may "creep" between stopping and starting periods. The spindle and delivery mechanism may be driven from individual motors or a common motor, and the initial acceleration of the delivery mechanism may be performed by a motor auxiliary to its individual motor.
