Definitions

  • the paperboard printer scorer slotter has a rotatable scoring member between a rotatable slotting member and a rotatable print cylinder.
  • the scoring member has a diameter 50 percent larger than the diameter of the slotting member.
  • Each of the scoring member and slotting member may be used selectively for either scoring or slotting paperboard blanks.
  • the present invention is generally directed to a printer scorer slotter capable of being used for extended slotting of paperboard blanks. Machines of this nature are known to the art. For example, see U. S. Pat. No. 3,031,937.
  • a standard machine of this type is adapted to print, score and slot paperboard blanks of a size whereby the leading edge of one blank is less than the circumferential distance of the upper slotting head from the leading edge of the next blank.
  • a 50 inch machine has an upper slotter head circumference of 50 inches. The distance between the leading edges of two blanks is 50 inches when feeding in the regular mode; that is, one blank for every revolution of the slotter head.
  • the skip feed mode of operation imposes certain limitations on the size of slots in blanks over50 inches in the direction of feed. Since the same knife must be used to cut the leading and trailing slots, only blanks that are 50 inches or less between the leading edge of the blank and the leading edge of the trailing slot can be accommodated. In order to circumvent the slotting limitations of skip feed I use the extended slotting" mode of operation.
  • the mechanism for facilitating extended slotting as disclosed in said above-mentioned patent performs satisfactorily.
  • the mechanism disclosed in said patent has the disadvantage of requiring set-up time of approximately two hours.
  • the present invention reduces the set-up time to approximately fifteen minutes.
