Abstract
1,137,870. Opening crimper filamentary tow. COURTAULDS Ltd. 26 April, 1966 [27 April, 1965], No. 17617/65. Heading D1F. In a continuous process for spreading crimped filaments of nylon, cellulose acetate or polyacrylonitrile, a tow 1 withdrawn from a container 2 passes over guides 3 and 4 and between bars 5, which lay it as a flat ribbon, between bars 6 (at right angles to bars 5) to define the edges of the ribbon and between closely spaced bars 7 (parallel to bars 5) which direct the tow to a stretching zone wherein the crimp is pulled straight without stretching the filaments 1a beyond their elastic limit. The zone is constituted by two pairs 8 and 9 of driven rollers the "fingers" i.e. circumferentially spaced longitudinal ribs or fingers, of each pair of which interengage thereby deforming and "beating" the filaments and, perhaps, promoting an electrostatic charge on the filaments which assists their subsequent separation. The filaments 1b then enter a relaxing zone, wherein the crimps reform thus causing the tow to spread, between rollers 9 and spaced, smoothe.g. rubber-, faced rollers 10 and 11 the former driven at the same peripheral speed as rollers 8 and the latter at approximately 3% increased speed. The width of the spread tow may be varied by adjustment of the relative speeds of the rollers.
