摘要

PROBLEM TO BE SOLVED: To make it easy to always set the flow direction of a double-side corrugated board sheet cut to the specified size, as specified and stack the corrugated board sheets at the sheet supply part of a sheet-fed printing machine. SOLUTION: In the corrugated board sheet obtained by laminating a liner base paper on both sides of a corrugating medium and cutting the laminate to the size of a sheet after lamination, a mark for regulating the printing direction is printed on the corrugated board sheet prior to reversing the corrugated board sheet at the delivery part of a corrugator.
