Abstract (en)
[origin: US2009221206A1] 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.
