Abstract: A two-up process for manufacturing one-piece binder covers including the steps of cutting a panel having opposed pairs of parallel sides; perforating the panel between two of its parallel sides to form a separating line to provide two rectangles connected together by the separation line; forming a recess at each end of the separation line so that each of the two rectangles has rounded corners upon separation of the two rectangles; dividing the blank by at least one pair of fold lines perpendicular to the perforated separation line and separating the blank into two binder covers each having four rounded corners.
