Abstract

Apparatus for making filaments.-The evaporative medium is constrained to pass the vicinity of the spinning orifices solely by means of suction applied to withdraw the evaporative medium from the cell, e.g. a draw-off device of the type described in Specifications 300,998 and 326,232, serves as a collector device. Additional evaporative medium may be introduced in the vicinity of the nozzle as in Specification 325,233, [Class 2 (ii), Cellulose &c.], further the draw-off device may be combined with the nozzle body and the additional evaporative medium may be introduced through the face of the nozzle in a manner similar to that described in Specification 341,075. The draw-off device comprises a perforated or slitted pipe arranged around the nozzle and corresponding in form thereto. Fig. 1 shows a ring-type nozzle 10 surrounded by a draw-off device 14 comprising a tubular ring with slits or openings 15. The device 14 is arranged at or slightly below the level of the nozzle, the openings 15 being so directed as to induce a flow of air close to the filaments 11. Fig. 3 shows a device in the form of a hood 19 mounted on the filter candle <PICT:0352922/IV/1> 21 and fitted with a draw-off pipe 20. Fig. 4 shows a draw-off device 14 associated with a collector in the form of a perforated plate 24 and with a tubular ring 22 for introducing additional evaporative medium. Fig. 5 shows an example of combined air-introducing and draw-off means associated with the nozzle body. Spinning solution supplied through a pipe 25 passes through passages 26 in the nozzle body 27 to a cavity 28 fitted with the nozzle 10. Air is admitted through a pipe 33 and passage 34 to a central cavity 32 and emerges through the hollow screwed member 30. A suction cavity 36 surrounds the jet and is furnished with a slot 39 near the level of the jet face and a drawoff pipe 35; the right-hand half of the figure shows the cavity 36 integral with the body 27, while the left-hand side shows the cavity formed in a cup 38. Further modifications are described. Specification 203,092, [Class 2 (ii), Cellulose &c.], also is referred to.
