    • PROBLEM TO BE SOLVED: To provide a method of manufacturing a sheet for making a box that reduces material loss when punching a blank sheet by a punching machine so as to contribute to the cost reduction. SOLUTION: A blank sheet obtained by cutting a material roll of corrugated cardboard is punched by a punching machine so as to manufacture a sheet for making a box in which a top surface, a first side face, a bottom surface, and a second side face, each provided with a flap on a short side, and a pasting margin are foldably connected in series. The method includes: a step for forming a blank sheet by cutting a material roll of corrugated cardboard; a step in which part to be punched out of a sheet for making a box is arranged such that at least one side of the sides to be opened of the top surface, one side to be opened of each flap, the other side to be opened of each flap, the side to be opened of the pasting margin is shared with one side of the blank sheet and the part to be punched out is formed on the blank sheet by printing; and a step in which the margin at the peripheral edge of the part to be punched out of the sheet for making a box is chucked as the chucking margin and transferred to the punching machine so as to punch out the part to be punched out.

    • 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
