  • Patent number: 5881620
    Abstract: An elongated rubber ejector is mounted to a die board that forms a part of a cutting die and the ejector functions to engage cut corrugated board and eject the same from the cutting die. The rubber ejector includes upper and lower faces or surfaces with each face including a series of spaced apart raised lugs with a series of spaced apart voids or relief areas disposed between the lugs. Lugs and relief areas formed on one face are staggered with respect to the lugs and relief areas formed on the other face. In practice, the lugs are compressed during a die cutting operation. Once the corrugated board has been cut and the die board and an opposed anvil have been moved apart, the lugs and the ejector expand and in the process the rubber ejector engages the cut corrugated board and ejects the same from the cutting die.

  • 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: 5636559
    Abstract: A resilient-scrap ejector is provided for a cutting die. The scrap ejector includes an elongated body made of a resilient material. The elongated body includes a longitudinally-extending web. A plurality of lugs extend from opposite sides of the web and are separated by notches. The notches provide void spaces which allow for deformation for the elongated body when the elongated body is subjected to compressive forces. The scrap ejector is located in a cavity or recess formed in the cutting die for ejecting and stripping scrap severed from the blank. By providing displacement zones or voids, the height of the scrap ejector can be increased without compressing the material beyond the limits of its resiliency.

  • Patent number: 5221249
    Abstract: A creasing rule is used in connection with a steel rule cutting die to form creases or fold lines in a blank cut from a sheet material, such as corrugated paper board. The creasing rule includes a base portion which fits into the slot of a die board, and a top portion which extends outwardly from the surface of the die board. The top portion terminates in a creasing edge, which, in cooperation with an anvil roll, compresses the sheet material to form a crease or fold line in the sheet material. The creasing edge of the creasing rule is formed with a plurality of undulations giving the creasing edge a generally sinusoidal form. The undulations on the creasing rule taper inwardly towards the plane of the base portion as the undulations extend from the creasing edge towards the base portion and finally merge into the flat base portion. The size or magnitude of the undulations can be varied depending on the thickness of the sheet material being used. Additionally, the pitch of the undulations (i.e.

  • 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.

  • Patent number: 4499802
    Abstract: A cutting die is provided with scrap ejection provisions for removing scrap from the die. The ejection provisions are particularly effective for ejecting elongate scrap from elongate openings such as slots which are formed in carton blanks and the like, the blanks being produced from sheet material, such as corrugated board. The ejection system includes resilient ejection member located between two parallel cutting rules, which members eject or push out the scrap from between the rules in an asymmetrical manner, exerting more force along one edge of the scrap than the other. This causes the scrap to twist and be more easily ejected. An additional ejection member is located outside one of the cutting rules to cause a portion of the blank to deflect to further aid in the scrap ejection.
