Abstract
Disclosed is a method for producing a board box by performing a box-making process of a corrugated board sheet which is formed to have dimensions of a plurality of board boxes wherein the yield of the board sheet and the production efficiency are enhanced and a countermeasure can be taken against paper powder. A method for making a box of a corrugated board sheet by performing a box-making process of a board sheet (S) which is formed to have dimensions of a plurality of board boxes and the cutting the board sheet (S) into dimensions of one board box comprises a step (I) for cutting the board sheet (S) into dimensions of one board box by a cut line (k) in the direction intersecting the conveyance direction (a) along a box making line (PL) after a ruling and grooving step (C) and before a pasting and folding step (E), and a speed increase step (J) for spacing the board sheets (S) and (S) thus cut by a set dimension following to the cutting step (I) by increasing the speed of the board sheets (S) and (S) while conveying toward a subsequent step.
