Abstract

We grasp the processes of an expert about the production of the handmade Japanese paper of Shuso in Ehime and the physical behavior in those processes. And, we find out the expert's skills that keeps the quality of the uniformity while long manufacturing time. We report the result of interlocking movement characteristics of the waist and neck in this study. The results of this reseach show that the neck movement of the expert has the fibers of Japanese paper tangle randomly. They also show that the expert modulates the quantity of the fibers by changing the height of the waist when he scoops up the fibers.
