FIELD: production of oriented cellulose films. SUBSTANCE: nonderivatized cellulose is dissolved in amino oxides and extruded through annular nozzle and external air gap down into setting bath. Produced film hose is blown up by working gas. By changing drawing ratio from 1 to 10 and blown up ratio from 1 to 10, uniplanar axial, planar or uniplanar orientation of film is effected. Method provides for regulation of mechanical properties of films produced by hose blown-bubble extrusion. EFFECT: higher efficiency. 8 cl, 1 tbl, 3 ex
