Abstract
A pressed crease-forming member is disclosed which is capable of forming a crease in a corrugated cardboard sheet along which the sheet can be bent with high accuracy, and which is a strip-shaped member having a crease-forming portion formed with an odd number of ribs extending in the longitudinal direction of the strip-shaped member with one of the ribs located at the widthwise center of the crease-forming portion. A plurality of cross grooves are formed on each side of the center rib, which is located at the widthwise center of the crease-forming portion, so as to be inclined relative to the center rib and spaced apart from each other in the longitudinal direction of the crease-forming portion. The cross grooves are arranged to longitudinally separate each of the ribs on both sides of the center rib into discontinuous rib portions.
