    摘要： A method of applying an indicia to the surface of a cellulose casing by non contact printing wherein the indicium is applied in-line with the casing manufacture at a location between the wet end and the dry end of the casing manufacturing process wherein the indicia comprises an ink that is cured and cross linked with the cellulose prior to the casing reaching the dry end of the process. The indicia preferably is in the form of a dot matrix pattern that is visible yet presents no barrier to the passage of smoke.

    摘要： A method and apparatus is disclosed for lacing an extruded tube of a non derivatized cellulose through an S-wrap to collapse the tube to a flat width. The lacing to form the S-wrap is accomplished without slowing the extrusion speed. At the start of the extrusion operation, the extrusion path leads between a pair of horizontally lacing members. After the leading edge of the extruded tube has passed downwardly through the space between the lacing members, the members are rotated as a unit to bring them into contact with opposite sides of the extruded tube. This collapses the and creates the S-wrap.

    摘要： Disclosed is a method of extruding a solution of cellulose and an amine oxide cellulose solvent as a tube about a sizing mandrel which diametrically stretches the extruded tube. An aqueous poly(ethylene oxide) solution is introduced into the interior of the extruded tube to facilitate passage of the tube over the sizing mandrel and to extract the amine oxide cellulose solvent from the tube. After such extraction, the aqueous poly(ethylene oxide) solution containing the extracted amine oxide cellulose solvent is contacted with an anion exchanger to remove the poly(ethylene oxide) so the amine oxide cellulose solvent can be recovered.

    摘要： In a method for forming a cellulose tube suitable for use as a food casing, in which a solution of nonderivatized cellulose, tertiary amine N-oxide and water is extruded through a die gap and the extruded tube is downwardly drawn through an air gap while being internally cooled and then is passed into a water bath, the tube transverse direction tensile strength being increased by drawing the extruded tube through an air length of at least about five inches and exposing the exterior surface of the extruded tube to cooling air in the air gap.
