Abstract
A double twisting machine is equipped with air flow control devices which create preferred conditions in the vicinity of each twisting station and, particularly, in the immediate vicinity of the twisting mechanism and the thread balloons. Pre-conditioned air, adjusted for temperature and humidity, is delivered through a nozzle located above each twisting spindle and is directed generally to the location of the thread guide loop. The protective container for the bobbin has a lower opening which permits the air flowing into the container from the top to emerge below where an exhaust conduit carries it away. A coaxial shroud surrounds the protective container and forms an annular air passage through which conditioned air may flow in both directions.
