Definitions

  • the lateral corrugator of the present invention is a machine for producing corrugated paperboard with the machine direction (predominant fiber orientation) of the liners parallel to the flutes, thereby significantly increasing box compressive strength for a given weight of paper.
  • Paper is nonisotropic in that pulp fibers tend to align in the machine direction as the paper is formed, resulting in a compressive strength that is typically 1.5 to 4 times greater in the machine direction than in the cross-machine direction.
  • a conventional corrugator produces paperboard with the liner machine direction oriented perpendicular to the flutes, and therefore perpendicular to the typical load, as illustrated in Fig. 1.
  • attempts have been made to design corrugators, including machine direction corrugators, to re-orient the fibers in the produced corrugated paperboard. These attempts have been largely unsuccessful in producing a commercially viable corrugator.
  • the lateral corrugator of the present invention forms flutes in a continuous web of paperboard medium using the conventional method of passing the medium web between intermeshing corrugating rolls with laterally oriented teeth and interspaced grooves. This is a proven technique, and utilizing medium in the conventional orientation, with the majority of the pulp fibers running across the flutes, preserves the resulting paperboard' s flat crush strength.
  • the lateral corrugator bonds the medium web to sheets of paperboard liner turned 90° relative to the medium web (i.e., machine direction parallel to the flutes in the medium web).
  • the lateral corrugator may be configured to use rolls of liner cut by an integral sheeter (Figs. 3-5), or it may alternatively use pre-cut liner sheets (Fig. 6).
  • top and bottom liner rolls are positioned laterally relative to the corrugator.
  • the liner rolls are unwound, spliced, and slit so the width of the liner webs is equal to the desired length of the final corrugated sheet (or a multiple of that length).
  • the liners are next preheated, preferably by preheater devices, and cut into sheets with the sheet length equal to the desired width of the final corrugated sheet.
  • the liner sheets are deposited onto a vacuum conveyor in a shingled arrangement.
  • the cross-machine location of the sheets on the belt is controlled by adjustable backstops for aligning the liner sheets with the medium web.
  • the vacuum conveyor holds the liner sheets in alignment prior to being fed into bonding nips.
  • First and second servo-controlled sheet-feeder devices such as servo driven nip rolls, grab the top and bottom liner sheets and feed them into top first and bottom second, or single face and double face, bonding nips.
  • Subsequent liner sheets are fed immediately adjacent the tail ends of the prior sheets to minimize the resulting gap between sheets.
  • the two sheet feeder devices are synchronized so that the seams between adjacent top liner sheets align with the seams between adjacent bottom liner sheets.
  • top liner sheets are bonded to the medium web at a single face bonding nip defined between a lower corrugating roll and a pressure roll in a manner similar to a conventional pressure roll-type singlefacer.
  • the newly formed singleface web is then wrapped around the pressure roll with the assistance of vacuum holes or grooves formed within the pressure roll.
  • adhesive is applied to the flute tips of the medium with a conventional adhesive applicator, such as a glue roll.
  • the bottom liner sheets are bonded to the singleface web at a double face bonding nip.
  • the combined double face web is then conveyed between sandwich belts over hot plates to cure the newly formed doubleface bond.
  • Weight rolls, or equivalent pressing devices provide force on the top sandwich belt to hold the double face web together until the bond cures thereby forming a final corrugated web.
  • the corrugated web is not capable of supporting significant tension because only the corrugated medium web is continuous, the top and bottom liners being formed of interspaced sheets.
  • the lateral corrugator in this configuration is much shorter than the wet end of a conventional corrugator.
  • the singleface web cools off on a bridge before the bottom liner is added.
  • the singleface web remains within the machine, heated by contact with the pressure roll and is then bonded to the lower liner sheets while it is still hot.
  • the hot plate section can be shorter than in a conventional corrugator and consumes less steam to cure the doubleface bond.
  • a cut-off knife is provided within the lateral corrugator and preferably uses a sensor to detect the seams between adjacent liners.
  • the cut-off knife makes the desired cut at the detected seam. If there are gaps between the liner sheets, the cut is biased to one side of the seam such that the resultant sheet includes three "clean" edges, and one edge with the medium protruding past the liner sheets. The medium edge may be subsequently trimmed to form a clean edge in later converting operations.
  • the remainder of the dry end of the lateral corrugator may essentially comprise the same components as in a conventional corrugator dry end.
  • the lateral corrugator of the present invention may be readily adapted for a variety of uses.
  • the top, bottom, or both liner sheets may consist of pre-printed labels, and the lateral corrugator may act as a litho-laminator.
  • This corrugator as described above may also utilize roll-fed continuous liner instead of sheets to make conventional corrugated board having a continuous medium web sandwiched between opposing continuous liner webs.
  • the lateral corrugator may further be configured in a manner similar to a conventional corrugator with a singlefacer, a bridge, a glue unit, and a doublefacer, all positioned in-line and spaced apart from each other.
  • the singlefacer includes a structure for facilitating the use of top liner sheets in the same manner as described above.
  • the doublefacer is similarly designed to accept bottom sheets of liner.
  • a seam detection sensor controls feeding of the bottom sheets of liner. This configuration may be retro fitable into an existing corrugator.
  • an object of the present invention is to provide a lateral corrugator for producing corrugated paperboard with increased box compression strength.
  • FIG. 1 is a perspective view of a box manufactured from conventional corrugation, with a portion of a liner enlarged to illustrate fiber orientation;
  • Fig. 2 is a perspective view of a box manufactured from the lateral corrugator of the present invention, with a portion of a liner enlarged to illustrate fiber orientation;

  • Fig. 10 is a schematic top plan view of a corrugator line including the lateral corrugator of Fig. 3.
  • pulp fibers are illustrated in an enlarged manner as reference numeral 10. As paper is formed, these fibers 10 tend to align predominantly in the machine direction, resulting in a compressive strength that is typically between 1.5 to 4 times greater in the machine direction as opposed to the cross-machine direction.
  • Box 12, as illustrated in Fig. 1 is of the type produced from a conventional corrugator wherein the fibers 10 of the liners 14 and 16 are oriented perpendicular to the flutes 18 formed within a paperboard medium web 20 sandwiched between the liners 14 and 16. As such, the fibers 10 are predominantly oriented perpendicular to the typical load applied in a vertical direction and illustrated by arrow 22.
  • FIG. 2 illustrates a box 24 including liners 14 and 16 with fibers 10 predominantly oriented parallel with the flutes 18 and the load 22.

  • conventional liner roll stands 44, 46 and 48, and conventional sheeters 50 and 52 are incorporated into the lateral corrugator 30.
  • a medium roll stand 44 rotatably supports a roll 54 of medium web 42 and is placed in-line with the lateral corrugator 30.
  • the medium paperboard web 42 is unwound and fed into the machine 30.
  • the medium 42 is preferably preconditioned by a conventional preheater 56 and a conventional preconditioner 58.
  • the medium 42 is then fluted between a first or upper corrugating roll 60 and a lower or second corrugating roll 62, in a conventional manner. More particularly, intermeshing teeth 64 and 66 supported by the corrugating rolls 60 and 62 define a corrugating nip 68 for forming flutes 18 within the medium web 42.
  • the medium web 42 wraps around the lower corrugating roll 62, and is held by positive pressure or vacuum through a pressure chamber (not shown) of the type known in the art.
  • Adhesive such as a starch-based glue, is applied to the flute tips 70 from a first or upper glue unit 72, typically comprising a glue roll 74 (Fig. 6) rotatably supported within a bath 75 of starch based glue.
  • top and bottom liner roll stands 46 and 48 are placed adjacent a rear side of the corrugator 30. Rolls 78 and 80 of the top and bottom liner webs 36 and 38 are unwound in the cross-machine direction (i.e., perpendicular to the direction of travel of the medium web 42).
