Abstract
Method for the take-up of continuous filament bundles of synthetic fibers at a high speed, which comprises introducing the continuous filament bundles discharged from an air jetting device and carried on the air stream into a bent tube provided downstream from the air jetting device, which is rotating in substantially reverse direction to that of the continuous filament bundles discharged from the outlet of the bent tube at a peripheral speed of the outlet thereof being 0.5 to 2.0 times the take-up speed of the continuous filament bundles (e.g. 2,000 to 6,000 m/min.), and receiving the continuous filament bundles into a receiving device provided downstream of the bent tube, and an apparatus useful for the take-up of the continuous filament bundles.
