The invention relates to a double twisting machine in which each twisting station has at least one protective container including therein a payoff bobbin and, located between the protective container, a rotatably driven turntable for providing thread rotation.
Double twisting machines of this type develop substantial amounts of heat so that, in an installation including many stations, even an air conditioning unit is not capable to provide the optimum conditions for the ambient air at the twisting stations. It is known to take measures in order to influence the air flow in the vicinity of the twisting station, for example to reduce the air resistance of the outer thread region or to draw off flying fibers (for example DT-Gbm 1,886,448, Fr-PS 1,378,696, DT Offenlegungsschrift 1,510,510, and DT-AS 1,267,153), however these mechanisms are not related to the maintenance of the desired conditions of the air in the vicinity of the twisting station.
