Abstract
A method for removing material between the panels of a foldable blank (100), includes the steps of: separating at least a portion of the blank with a contoured line (25) to define a first panel (15) and a second panel (20), terminating the contoured line at a vertex (V), selecting one of the first and second panels as a trimmed panel (15) from which material is to be removed, defining a first line (R) that includes a pair of first and second points (P1, P2) on an edge of the trimmed panel, and removing a portion (A) of the trimmed panel defined by the first line and a section of the edge lying between the first and second points.
