Abstract
791,610. Crimping, guiding and tensioning threads. HEBERLEIN & CO., AKT-GES. Dec. 22, 1955 [Jan. 24, 1955], No. 36784/55. Classes 120(2) and 120(3) In the manufacture of crimped threads of synthetic material e.g. polyamides, polyvinyl, or polyesters, by temporarily twisting threads together to form a length of transiently twisted doubled yarn, subjecting such yarn to heat treatment, removing the temporary twist and then separating the threads, the uncrimped threads are fed obliquely to and converge at the length of doubled yarn under tensions that are individually controlled to equality, the angles between the convergent and divergent threads at their entry to and departure from the doubled yarn and the axis thereof are respectively equal, and the angles between planes containing the axis of the doubled yarn and adjacent converging and diverging threads are equal. As shown in Fig. 1, threads 1 and 2 travelling from bobbins 3 and 4 pass through separate thread-tension means 5 and 6, a guide 7, feed rollers 8 and a shield 9 (provided with two guide surfaces, one for each thread, in the form of openings), beyond which the threads converge to form a doubled yarn which passes through a tubular device 10 and is heated thereby (as by steaming under pressure), and thence through a false-twister 11 the doubled yarn passes over a guide pulley 12 and a jockey pulley 13 and the threads are separated by a rod 14, withdrawn by rollers 15, which rotate relative to the rollers 8 at the same or increased speed e.g. to stretch the threads by 0.5 per cent-20 per cent of their original lengths, and wound on a bobbin 16 (or separate bobbins). The length of doubled yarn between the twister 11 and the separation of the threads in relation to the number of turns temporarily imparted thereto may be such as to limit the twist remaining in any short lengths of threads at the point of separation to not more than 1 turn per cm. Figs. 3 and 5, and Figs. 4 and 6 respectively show guides for converging and separating three and four threads by provision of symmetrically arranged apertures and notches in shields 9. In the gate-type tensioner shown in Fig. 7, the thread is gripped between fork-like members 17 and 18 with a force determined by a weight 20 suspended from the member 17 and tending to rotate it about the axis 19.
