[Also in Groups XXII, XXIII and XXIV] A false twist spindle S is located to be driven between a pair of interengaging double flanged rollers 83, 85 and a driving roller 24, the roller 24 having a flexible tyre C such that expansion of the tyre due to centrifugal forces enables it to drive the spindle S. The driving roller 24 is mounted, together with a lower, drive transmitting roller 61, on a shaft 51 rotatable in a pivotable frame 33, the supporting spindle of which has, below its bearing sleeve 36, a lever 40 engaged by a spring 42 to press the roller 61 into contact with a primary driving belt 62. The twist spindle is axially located by flanges 91 thereon engaging between adjacent flanges of the rollers 83, 85 which have spindles 81, 82 mounted in a carriage 74, the carriage being urged towards the driving roller by a spring 97. In Figs. 3 and 4 (not shown), two carriages 33 may be mounted at a single location with the carriage supporting spindles arranged concentric. The centrifugally expanding tyre C which is preferably of a synthetic, rubber-like, plastic may take a variety of forms, see Figs. 2, 6, 7, 8 (not shown). The carriage 74 may be provided with an upper guard plate. Specifications 464,981, 519,995 and 789,626 are referred to. |
