<p>The shaft has fibers compressed in the shaft by performing a shaking process, where the shaking action is automatically varied based on measured values of points corresponding to measuring points during production to obtain target density. A measurement process is performed in a material flow direction after completion of the shaking process. An intensification process is performed in the shaft by increasing a shaking frequency, extending a shaking path or by extending a shaking duration.</p> |
