FIELD: pulp-and- paper industry. SUBSTANCE: method involves extrusion of viscose alkali solution through jet into precipitation bath followed by drying and winding resulting regenerated cellulose tubular shell. In the extrusion process, liquids caught in extruded tubular shell and gases formed in regeneration (precipitation) stage are brought in countercurrent contact by way of flattening tubular shell to prevent caught media from passage through further process stages. These media are removed through internal hole of above-mentioned nozzle. EFFECT: enhanced process efficiency. 5 cl, 3 dwg, 5 ex
