    • PROBLEM TO BE SOLVED: To provide a method of manufacturing sheet for box making by which the material loss in punching a blank sheet with a punching machine is reduced and which is carried out with excellent work efficiency. SOLUTION: In the manufacture of the sheet for box making, the needless parts of both sides extending in the longitudinal direction, of a original corrugated board are cut, the original corrugated board is divided into two pieces at an optional boundary extending in the longitudinal direction of the original corrugated board, the blank sheet obtained by cutting in the original corrugated board in the width direction is punched with a punching machine to manufacture one or two or more sheets for box making per one blank sheet. In such a case, two sheets for box making are arranged in a position line-symmetric to an optional boundary on the original corrugated board so that top surface parts of respective two sheets for box making are abutted and the margin parts of two pieces of the sheet for box making turns to the side parts of the original corrugated board and further a part of the sheet for box making which is to be punched is formed so that the side of the top surface part and/or the side of the margin part is formed by dividing at the optional boundary and/or cutting the needless parts. The original paper board is handled by the same way. COPYRIGHT: (C)2010,JPO&INPIT
