The purpose of this study is to make the conventional ageing process for alkali-cellulose into a continuous process and to reduce manufacturing cost. Several test machines have been made and studied, and the last of them has been found to satisfy all the conditions required of a continuous ageing machine. The total length of time for ageing by this machine is about 3.5 hours, and the products obtained are superior to those made by conventional processes.
