Introduction of Color Web―Inspection―System at Kishu Mill

Abstract

Various defects occur even if they put a papermaking process as demand quality of the paper diversifies by other kinds small lot apparition product and in front of the visitor needs correspondence. To the defect detector which is an important instrument preventing a defective article outflow to the in front of the visitor, superior ability for inspection and stability are found.
Four paper machines operated, and a defect tester of the examination with each F elt side was installed in the Kishu Mill, Hokuetsu Kishu Paper Co., Ltd. but the inspection ability that a light color defect where both sides inspection and a color line defect and the making paper of the light color included it was detectable became unavoidable because I hit it and added the defect detector of the No．6 machine to conventional fine paper, color fine paper in after 2009, and special paper was targeted for inspection in transfer papermaking from other factories. In addition, I carried out color defect detector introduction and winder support equipment update in 2011 because the defect check with the winder, the processing number of times increased by Tokushu Paper Mfg. papermaking, and machine slowdown came to produce an operation trouble with the winder support equipment of the threshold method in operation. I introduce introduction progress and operation experience this time.
