The design assignment of connecting portions on a paperboard is important in order to stabilize the transport of the paperboard during die cutting. A mechanical estimation of various deformations of connecting portions is desired to predict an allowable assignment of connecting portions. The main purpose of this study is to reveal the elongation properties of the connecting portion of a paperboard with respect to several primary parameters such as nick width and crushed blade tip thickness. The result shows that there is a lower bound width of the connecting portion; the tensile strength of the connecting portion strongly depends on the cutting direction and grain (machine) direction of the paperboard. It is also clarified that the presence of string like dust affects the tensile strength of the connecting portion and that increasing blade tip thickness reduces the tensile strength of the connecting portion.
