  • Patent number: 5641551
    Abstract: Toothed perforating rules upon the die roll of the rotary die apparatus form tear strips, punchouts, reverse fold lines, nicking connections and similar weakened or frangible sections in corrugated paperboard sheets during passage thereof through the nip between the die and anvil rolls of the apparatus. The teeth of the die rules are tapered and sharpened, and produce perforations in the paperboard panel that decrease in size with increasing distance from the inner liner of the paperboard sheet. The teeth produce an array of relatively long slits in the inner liner of the sheet, and underlying shorter slits within at least one other ply of the panel. The toothed die members may extend at any desired angle or angles relative to the machine direction of the apparatus and/or relative to the direction of the corrugations within the paperboard panel.

  • Patent number: 5582571
    Abstract: The present invention provides an apparatus and method for perforating and creasing a paperboard sheet utilizing a rotary die process. The method and apparatus employ a die rule that comprises a base adapted to be attached to a die roll of a rotary die machine, a plurality of tooth elements, and open spaces between at least some of the plurality of tooth elements. Each of the plurality of tooth elements comprises a body portion that is fixed to and extends radially outwardly from the die roll and a laterally-tapered tooth portion. Each open space is defined by lateral portions of adjacent teeth element body portions and by the base outer edge. The body portion preferably extends radially outwardly from the base so that substantially all of the tooth portion penetrates the outer surface of the paperboard, and the base outer edge extends outwardly so that it engages and creases the inner surface of the paperboard.

  • Patent number: 5194064
    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.

  • Patent number: 5111725
    Abstract: The scrap ejector has a relatively long and thin body made of stainless steel or other resilient and durable material. The leading end portion of the body overlies and is secured to the outer surface of the die roll. In its undeflected condition, the trailing end portion of the body is spaced radially from the die roll. In one embodiment the body has a pad of compressible elastomer upon the surface thereof distal from the die roll, and in another embodiment the body has an arcuate portion projecting from the aforesaid surface of the body. During passage of the scrap ejector through the nip between the die and anvil rolls engagement between the anvil roll and the resilient pad (in the first embodiment) or the arcuate portion (in the second embodiment) deflects the trailing end portion of the body to a position wherein its terminal end is closely adjacent the surface of the die roll and the leading surface of the cutting rule which trims the leading edge portion of the paperboard stock.
