Abstract
Former sheet cutters had to rest while piled sheets of paper is transfered. To perform continuous non-stop running there were two choices, installing a reject gate or a dual layboy system.
However they had still some problems as follows :
(1) Poor running efficiency.
(2) Poor work efficiency due to happening inaccurate cut-length at sheet cutter start/stop.
(3) Mean production yield rate.
(4) Many complex works to force operators.
(5) Big amount of initial cost.
To solve the problems mentioned above Minami-Senju developed the first Continuous Pile Change System in 1981. In 1986, further advanced improvement on the system featuring what there were nothing of rejected sheets during pile change was made under a cooperation work together with Mitsubishi Paper Mills, Ltd., Hachinohe Mill.
