CA 2474167

The invention relates to an installation (1) for producing continuous shaped bodies (2) of a molding material, such as a spinning solution containing water, cellulose, and tertiary amine oxide. Continuous shaped bodies are produced by spinning means comprising an extrusion head (3), through which the molding material is extruded to form continuous shaped bodies, a precipitation bath (5) containing a precipitation bath solution, and an air gap (4) which is arranged between the extrusion head (3) and the precipitation bath (5). After being extruded, the continuous shaped bodies (2) are first guided through the air gap (4) and then through the precipitation bath (5). In order to make it easier to control the proper functioning of the installation, the inventive installation comprises a control area (16) which is positioned in front of the spinning means and is accessible to operating personnel (17), and the air gap (4) is arranged at a height (A) from where said air gap can be viewed in an unobstructed manner, said height (A) being randomly set according to the central viewing range (19) of an operator (17) who stands upright in the standing area (16) and looks essentially straight ahead.

L'invention concerne une unité (1) de production de corps à forme continue (2) à partir d'une matière moulable, telle qu'une solution de filage contenant de l'eau, de la cellulose et de l'amineoxyde tertiaire. Le procédé de production des corps à forme continue fait appel à des moyens de filage comprenant une tête d'extrusion (3) permettant d'extruder la matière moulable pour constituer des corps à forme continue, un bain de précipitation (5) contenant une solution de bain de précipitation, ainsi qu'un intervalle d'air (4) disposé entre la tête d'extrusion (3) et le bain de précipitation (5). Une fois extrudés, les corps à forme continue (2) sont conduits à travers l'intervalle d'air (4) jusqu'au bain de précipitation (5). L'objectif de l'invention est de pouvoir vérifier plus aisément si le fonctionnement de l'unité est conforme. A cet effet, l'unité comprend une zone de surveillance (16) disposée en amont des moyens de filage et accessible aux opérateurs (17). En outre, l'intervalle d'air (4) est disposé de façon à être vue librement, à une hauteur (A) déterminée par le champ visuel central (19) d'un opérateur qui est debout dans la zone d'arrêt (16) et qui dirige son regard dans une direction sensiblement horizontale.
