| description | The invention relates to a method for the production of cellulosed flat sheeting and cellulosed membranes in the form of flat membranes, wherein a solution of cellulose in an aqueous tertiary amino oxide is shaped out as sheeting by means of an extrusion die having an oblong extrusion gap, and then passed through an air gap into a regenerating bath, in which the cellulosed flat sheeting is formed. The method is characterized in that the cellulosed flat sheeting is stretched transversally after entry into the regenerating bath. |
