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.

L'invention concerne un dispositif de filature pour produire des fils fins par épissurage, avec plusieurs filières saillantes disposées dans une section de filière, comprenant des ouvertures de filature, desquelles sortent les masses filées sous forme de monofilaments, et avec plusieurs buses d'accélération associées aux ouvertures de filature, notamment des buses de Laval, dont la section transversale se rétrécit et s'élargit après la plus petite section transversale, des moyens étant conçus pour l'alimentation en flux de gaz qui entourent les monofilaments et qui sont accélérés par les buses d'accélération. La buse d'accélération est réalisée, dans une section de buses à gaz au moins partiellement en forme de plaque, sous forme de renfoncement en forme d'entonnoir, dans lequel la filière s'engage en formant des canaux d'écoulement de gaz. On dispose des moyens pour le déplacement relatif de la section de buse à gaz et de la section de filière l'une par rapport à l'autre, de telle sorte que la section transversale d'écoulement des canaux d'écoulement de gaz puisse être modifiée et/ou que la position de la section transversale la plus petite des buses d'accélération puisse être ajustée en fonction des ouvertures de filature.
