Abstract
A spinning apparatus for producing fine threads by splicing, which comprises a plurality of protruding spinneret jets disposed in a spinneret jet portion and having spinning orifices from which the spinning dopes exit as monofils and having a plurality of acceleration jets, in particular Laval jets, whose cross section reduces, only to widen downstream of the smallest cross section, which are assigned to the spinning orifices is proposed to be provided with means for feeding gas streams which surround the monofils and are accelerated by the acceleration jets. The acceleration jet, in an at least partially plate-shaped gas jet portion, is constructed as a funnel-shaped depression into which the spinneret jet reaches to form gas flow channels. Means for relative displacement of the gas jet part and of the spinneret jet part relative to one another are provided such that the flow cross section of the gas flow channels is alterable and/or the position of the smallest cross section of the acceleration jets is adjustable in relation to the spinning orifices.
Claims (15)
1. Spinning device for producing fine threads by splitting, having a plurality of protruding spinning nozzles with spinning openings which are disposed in a spinning nozzle part and from which the spinning materials emerge as monofilaments and having a plurality of acceleration nozzles, in particular Laval nozzles, which are assigned to the spinning openings and the cross-section of which is reduced and widens after the smallest cross-section, means being provided for supplying gas flows, which surround the monofilaments and are accelerated through the acceleration nozzles, characterised in that the acceleration nozzle is configured in an at least partially plate-shaped gas nozzle part (27) as a funnel-shaped depression into which the spinning nozzle engages forming gas flow channels and in that means for relative displacement of the gas nozzle part and of the spinning nozzle part relative to each other are provided such that the flow cross-section of the gas flow channels can be changed and/or the position of the smallest cross-section of the acceleration nozzles can be adjusted relative to the spinning openings.
2. Spinning device according to claim 1, characterised in that the means for relative displacement comprise guides and/or sliding rods.
3. Spinning device according to claim 1 or claim 2, characterised in that the means for relative displacement is configured as adjustment screw device which is disposed between gas nozzle part and spinning nozzle part.
4. Spinning device according to one of the claims 1 to 3, characterised in that a gas chamber with at least one gas supply is provided between spinning nozzle part and gas nozzle part, said gas chamber being in communication with the gas flow channels and into which the spinning nozzles protrude.
5. Spinning device according to one of the claims 1 to 4, characterised in that the gas nozzle part is provided with a frame-like edging, the region of the spinning nozzle part which has the protruding spinning nozzles being inserted between the edging.
6. Spinning device according to one of the claims 1 to 5, characterised in that a self-adjusting seal is provided between spinning nozzle part and gas nozzle part.
7. Spinning device according to one of the claims 1 to 3, characterised in that the gas nozzle part is configured as a hollow body which is engaged by the funnel-shaped depressions, the space within the hollow body forming a gas chamber and openings directed towards the spinning part being provided, which connects the gas chamber to the gas flow channels.
8. Spinning device according to claim 7, characterised in that a formed part (11) respectively is inserted between the spinning nozzle of the spinning part maintaining air gaps (12) relative to the gas nozzle part for heat insulation, which gaps extend essentially up to the spinning openings, the gas flow channels (5) being formed between the formed parts (11) and the gas nozzle part (2).
9. Spinning device according to claim 7 or 8, characterised in that the openings (4) are disposed annularly around the funnel-shaped depressions.
10. Spinning device according to one of the claims 1 to 9, characterised in that the gas chamber is sealed externally.
11. Spinning device according to one of the claims 1 to 10, characterised in that the gas nozzle part (2) and the spinning nozzle part (1) have a plurality of funnel-shaped depressions and spinning nozzles which are disposed in rows adjacent to each other, the spinning- (13) and acceleration nozzles of the one row being disposed offset relative to the other row.
12. Spinning device according to one of the claims 1 to 11, characterised in that the combination of gas nozzle- and spinning nozzle part comprises a plurality of gas- and nozzle part segments which are exchangeable respectively.
13. Spinning device according to one of the claims 1 to 12, characterised in that a plurality of gas- and spinning nozzles (1, 2) are disposed adjacent to each other.
14. Spinning device according to one of the claims 1 to 13, characterised in that a distribution device for an additional fluid is provided on the gas nozzle part at a spacing from the exit of the acceleration nozzles, which fluid impinges upon the threads which have split from the monofilament.
15. Spinning device according to claim 14, for use in the production of lyocell threads, the additional fluid being water.
