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.
A 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, said bent tube being bent in the radial direction toward the tip thereof and in the tangential direction and the outlet thereof is opened in the tangential direction, said bent tube rotating in substantially a reverse direction to that of the continuous filament bundles discharged from the outlet of the bent tube, with the peripheral speed of the outlet being 0.5 to 2.0 times the take-up speed of the continuous filament bundles, and receiving the continuous filament bundles into a receiving device provided downstream from the bent tube.
An apparatus for the take-up of continuous filament bundles of synthetic fibers at a high speed, comprising final take-up rollers, an air jetting device provided downstream of the final take-up rollers, a bent tube provided downstream of the air jetting device, the outlet of the bent tube being opened downward in an angle of 15.degree. to 45.degree. relative to the horizontal direction, and a receiving device provided downstream of the bent tube, said bent tube rotating in substantially a reverse direction to that of the continuous filament bundles discharged from the outlet of the bent tube with the peripheral speed of the outlet being 0.5 to 2.0 times the take-up speed of the continuous filament bundles.
