Abstract

1,235,682. Unravelling yarns. COURTAULDS Ltd. 22 Oct., 1968 [23 Oct., 1967], No. 48085/67. Heading D1W. Knitted fabric is unravelled in an apparatus comprising a casing 2 having an aperture 3 for entry of the yarn 14, a means 11 for maintaining a sub-atmospheric pressure in the casing and a pair of rollers 6, 7 forming a nip adjacent the aperture. At least one of the rollers is driven in a sense that its surface adjacent the other roller moves in a direction from the aperture into the casing. As shown, fabric to be unravelled is held on posts 13, or a clamp, and the end is fed into the aperture 3 with the rollers 6, 7 held apart. The rollers are then closed and the unravelled end passes into container 2 via guide 16. There may be a knife edge between the post 13 and the aperture 3. An air stream may be directed over the rollers at a point remote from the aperture and in a direction counter to their direction of rotation, see Fig. 2 not shown.
