Abstract
A balance correction sheet corrects a whole pressure balance of a punching machine, in which a punching die and a cutting plate for receiving blade tips of the punching die are attached to be opposed to each other. A method of forming the balance correction sheets includes attaching a balance correction die having a plurality of punching blades disposed at a predetermined interval to the punching machine, intermediately inserting the blade tips of the punching blades into a middle of laminated sheets formed by laminating peelable sheets so that incisions are formed in a depth direction of the laminated sheets, and partially removing the laminated sheets depending on depths of the incisions so as to prepare the balance correction sheet.
