The invention relates to an apparatus for manufacturing multifilament threads with at least one hot-air module 6 for drawing or relaxing the thread Y. To manufacture multifilaments with particularly high strength and to avoid the problems of the bearings of the rollers 9, 10 in the hot-air modules 6, at least one apparatus is provided for screening the hot stream of air from the rollers 9, 10, 10' of the or each hot-air module 6. Such apparatus may, for example, take the form of divider sheets 12. To facilitate the introduction of the thread Y into the hot-air module 6, it may be furthermore provided according to the invention that two rows of rollers 9, 10 facing each other are arranged in the or each hot-air module 6, at least the rollers 10 of one row being arranged in the direction of the rollers 9 of the other row and movable beyond these so that a meander-shaped arrangement of the thread Y can be achieved automatically in the hot-air modules 6. When the rollers 9, 10 are displaced, the divider sheets 12 or the like are folded away, displaced, or the like. |
