Abstract
<PICT:0419527/IV/1> In the production of artificial threads by the downward dry spinning method, the winding apparatus is located inside the spinning cell and the direction of travel of the gas inside the whole spinning cell is approximately at right angles to the direction of the threads. Preferably, several gas currents are passed across the cell from inlets situated at different heights on one side of the cell to correspondingly placed outlets at the opposite side. Gas removed from one of the outlets may be wholly or in part reintroduced at another zone of the cell. The gas current passing across the cell in proximity to the nozzle may be pumped in a cycle, part being removed for recovery and replaced by gas which has passed across the cell at another level. As shown in Fig. 2, heated air is introduced at the inlet a<1> and withdrawn at b<1>. It is then re-introduced at a<2>, withdrawn at b<2>, and again passed through the cell from a<3> to b<3>. As shown in Fig. 3, air is introduced at a<1> and withdrawn at b<1>. Another current of air passes across the cell in the region of the winding apparatus and is re-introduced at a<3> near the top of the cell. As shown in Fig. 5, the main current of gas passes from a<1> to b<1> and back to a<1> through the fan x. A part of the air withdrawn at b<1> is drawn by the fan y to inlet a<2> and passes across the cell to b<2>. A corresponding quantity of fresh air is introduced at a<3>, withdrawn at b<3> and added to the main current.
