In the Folio sheet cutter of our factory, because jamming occurred when adsorption timing of sheet slipped off in a suction box part, we adjusted a timing at the change of dimension and change of shifts. Because products exhausted at this time, it became the factor of a decrease in product yield. In addition, because the jumping out of the sheet occurs to a product when we adjust a timing, it was necessary to sort a product. Therefore we installed an image processing device and worked on loss reduction.
