1,155,073. Finishing yarns. TEXTILE MACHINE WORKS. 9 Aug., 1966 [17 Aug., 1965], No. 35679/66. Heading D1F. In apparatus for bulking multifilament crimped yarn e.g. as produced by a knit, heat-set and deknit process; by a rubbing action which separates individual filaments of the crimps or corrugations from their nested relationship so that they project in different planes, yarn Y is pulled in a tortuous path between wear resistant e.g. ceramic cylinders 40 of at least two nested tiers thereof contained in a housing 21. A plate 42, which may be manipulated by a pin 43, acts through a layer 41 of compressible material such as sponge rubber to exert pressure adjustably determined by a locking screw 45 or a lever arm having a weight mounted for adjustment thereon, Fig. 5 (not shown). |
