The present invented method is as follows: during the paper-draft process, the semi-drying paper which comes out of the front drying cylinder is fed into the radial deviation drying cylinder set or the radial deviation gear set in the rear section of the paper machine. All the cylinder diameters of the drying cylinder set are gradually reduced or the diameters of gears for driving cylinders are gradually increased. This structural form can make the paper to naturally contract at the time of drying. The paper extensibility is raised by 4-6%, and as compared with the common paper, it is increased by two times, thus raising paper elasticity and toughness. |
