ABSTRACT:
An apparatus for transferring threads from the spinning-cum-finishing part of a machine for continuous production of artificial threads to the take-up and winding arrangement thereof includes thread guiding tubes with thread guides for centering the thread along the axis of the tube and an ejector nozzle for feeding a stream of air together with the thread into each respective tube. The thread guide situated at the exit end of the tube includes a cup-shaped member with an aperture made through the center of the bottom thereof and a port made in the side wall of the member, communicating with the aperture. There is mounted adjacent to the cup-shaped member, in opposition to the port thereof, a screen for slowing down the air stream issuing from the tube together with the thread. This structure prevents misdirecting of the thread to the nearby parts and stations of the take-up and winding arrangement.
