Abstract
The ratio of the rotation speed Nr of the take-up roller (take-up rotation speed) and the rotation speed Nu of the feeding roller (feeding rotation speed) is used. That is, knowledge that the roll diameter Drr of the sheet S taken up on the take-up roller is given by a function using the ratio of the rotation speeds Nr and Nu as a variable was obtained. Accordingly, the roll diameter Drr is computed from this ratio.
