ようになされていた。[0003] Paper made by a paper machine is taken up by a reel stand, rolled into a roll paper 10 and passed to a downstream process. At this time, there is a winding hardness as an element that affects the quality of the roll paper 10. For example, if the hardness at the beginning of the winding is low, the layer at the beginning of the winding is tightened by the paper layer that is wound later, and wrinkles occur in the layer at the beginning of the winding, resulting in waste paper. Therefore, conventionally, the following has been performed.

The paper 3 made upstream is wound up. At this time, the paper 3 is wound up while applying a constant nip force with the hydraulic cylinder 5 between the paper 3 and the reel drum 4 while applying a constant tension. The winding hardness changes depending on the tension and the nip force.

により巻硬さを調べる。[0005] The position of the reel drum 4 is fixed, and when the winding diameter of the paper on the spool 2 increases, the arm 1 rotates in the direction of arrow 9 in the figure. A rotary encoder 7 is provided on the rotation shaft 6 of the arm 1 and measures the rotation angle θ of the arm 1. Thereby, the winding diameter on the spool 2 can be calculated. Another rotary encoder 8 is connected to the spool 2 to measure the number of rotations of the spool 2. The outer diameter of the paper layer formed every predetermined number of windings formed during the winding operation is measured, and the winding hardness is checked by calculating the density using the following equation.

という問題がある。The above-mentioned conventional methods for detecting the hardness of roll paper and the method for winding the same have the following disadvantages. That is, after measuring the density of the n-th layer, n + 1
Since the paper is wound in layers, n + 2 layers,..., The density when measured is different from the density when finally rolled up under the influence of the upper layer fastening force. Then, there is no means for estimating the final density, and the roll hardness of the roll paper cannot be detected accurately, and consequently, there is a problem that a roll paper having an appropriate roll hardness cannot be obtained.
