PURPOSE: To maintain the parallelism of two rollers of a fluid false twisting and untwisting device at a high degree of accuracy, and to improve the operability, by engaging top rollers attached to a bracket, which is fixed to the nozzle block swingably, with the bottom rollers detachably.
CONSTITUTION: The box-shaped bracket 14 is fixed and engaged with the nozzle block 6 swingably about the fulcrum 13. The fulcrum 14B of the bracket 14 is engaged with the T-shaped arm 15 and the swing arm 16 worked by a spring. The downstream opening of the top ane the bottom apron bands 5D and 4D is retained by the tension coil spring 17 and the stopper 14C attached to the bracket 14. Staple fibers are fed and transferred by the pressing and turning forces of the bottom and the top rollers 4A and 5A, twisted by the fluid false twisting nozzle 7, and untwisted to wrap skin fibers around the zero twist core bundle.
EFFECT: Ready removal of fibers lapped around rollers.
