Filed: 1993-12-27
Abstract: PURPOSE:To provide a paper-making machine controller which can prevent the deterioration of paper quality caused by fluctuation in the line speed, when the control level is switched, to simplify the operations. CONSTITUTION:When the paper making machine is operated by the draw control, the value set in the draw setter is detected at the set-draw detector 22.
