ABSTRACT:
The creasing rule includes elongate creasing members that extend outwardly from opposite sides of a central axis of the rule. The creasing members on each side of the rule are spaced laterally from each other and are in staggered, non-aligned relationship with the creasing members upon the opposite side of the rule's axis. Each creasing member has a relatively tall head section adjacent the rule axis, and decreases in height between the head section and the opposite end of the member. The members preferably are formed of durable plastic material and are so mounted upon the die board of the rotary die apparatus as to be quickly and easily replaced when desired. Head sections of the creasing elements form a relatively wide and deep primary crease in the paperboard material of the panel, and medial and end sections of the creasing members simultaneously form secondary creases that extend outwardly from opposite sides of the primary crease.
