Abstract
A rotary cutting die apparatus for cutting and perforating corrugated board comprises a die board having one or more perforating rules. The perforating rule includes a series of spaced apart perforating segments disposed along one edge of the rule. Each perforating segment includes opposed angled shoulders that reduce or minimize the tendency of the corrugated board from becoming hung-up or held on the perforating segments when the perforating segments penetrate the corrugated board to form perforations therein.
