摘要

PROBLEM TO BE SOLVED: To provide a push-ruling member that enables an accurately-foldable ruled line to be formed for a corrugated fiberboard sheet.SOLUTION: One end of a metal strip-shaped plate 11 serves as a ruling part 12, and a plurality of recesses 13 for molding a rib are continuously formed in the lengthwise direction of the ruling part 12. The recesses 13 for molding the rib are formed as X-shaped grooves. The rib 16A, the plane of which assumes an X-shape, is formed on a groove bottom surface B of a ruled line L by pushing the ruling part 12 into a corrugated fiberboard sheet A.
