Abstract
1,081,401. Yarn-forwarding rollers. IMPERIAL CHEMICAL INDUSTRIES Ltd. May 6, 1965 [May 20, 1964], No. 20718/64. Heading B5B. Yarn-forwarding apparatus contains a driven roll 7, the outside end section of which has a low-friction surface 10 and the remainder has a highfriction surface 9. Surface 10 may be polished and surface 9 matt. In stringing-up the apparatus, yarn 11 is caused to make wraps, sufficient in number to prevent slip, round the feed roll 1 and idler separator roll 2 with skewed axes, is wrapped once round snubbing-pin 3 and is then passed round guides 4 and 5, and hence to draw roll 7 and idler separator roll 8, round which it is caused to make a number of wraps. Roll 7 is driven with peripheral speed at least 3 times that of roll 1. Guide 5 is initially so positioned that the yarn is in contact with the low-friction surface 10. As there is considerable slip, the free end 12 of the yarn has a reduced tendency to become wrapped round roll 7. When the requisite number of wraps have been made guide 5 is moved to the alternative position, and the yarn under the action of guide 4, moves on to the high-friction surface 9, whereon it is accelerated to the peripheral speed of the roll. The yarn is taken off roll 7 via low-friction surface 10, thus reducing the possibility of a back-wrap. The apparatus may comprise two driven rolls, with corresponding high and low friction sections.
