Abstract
In the manufacture of fiber-reinforced cellulose casing wherein a paper tube is passed downwardly over a mandrel, impregnated with viscose and subjected to the action of a coagulating liquid to regenerate cellulose, a gas stream is flowed upwardly within the tube as the tube is passed over the mandrel, the gas stream pressure being sufficient to maintain the cylindrical dimensions of the tube but insufficient to cause a measurable change in the dimensions of the tube walls whereby contact of the internal surface of the impregnated tube with the mandrel is reduced or substantially eliminated.
