A method according to claim 1, wherein said adhesive is at least 25 weight percent solids, balance water. 16. A method according to claim 1, wherein said adhesive is at least 27 weight percent solids, balance water. 17. A method according to claim 1, wherein said adhesive is at least 30 weight percent solids, balance water. 18. A method according to claim 1, wherein said adhesive is at least 30 weight percent solids, balance water, and said adhesive layer has a thickness of 0.002 inches. 19. A method according to claim 1, wherein said adhesive is at least 30 weight percent solids, balance water, and said adhesive layer has a thickness of 0.003 inches. 20. A method according to claim 1, wherein said adhesive is at least 30 weight percent solids, balance water, and said adhesive layer has a thickness of 0.004 inches. 21. A method according to claim 1, wherein said adhesive is at least 30 weight percent solids, balance water, and said adhesive layer has a thickness of 0.005 inches. 22. A method according to claim 1, wherein said adhesive is at least 30 weight percent solids, balance water, and said adhesive layer has a thickness of 0.006 inches. 23. A method according to claim 1, wherein said adhesive coating on said applicator roll has a thickness of 0.008 inches or less. 24. A method according to claim 1, said adhesive coating having a thickness of 0.006 inches or less. 25. A method according to claim 1, wherein said adhesive coating on said applicator roll is a uniform adhesive coating provided by a metering rod held in position against said applicator roll outer surface at a position subsequent to a coating position of said applicator roll, said metering rod removing excess glue from said outer surface of said applicator roll to provide said uniform adhesive coating. 26. A method according to claim 25, wherein said metering rod is adjusted by an isobar assembly to provide a desired thickness of said adhesive coating on said outer surface of said applicator roll, said isobar assembly comprising a metering rod assembly for holding said metering rod, said metering rod assembly including a channel member, a holder, and a tubular pressure-tight bladder therebetween, said channel member forming a longitudinally extending channel, said holder extending into said channel and being moveable toward and away from said applicator roll within said channel member, said holder having a groove therein for retaining said metering rod therein. 27. A method according to claim 26, wherein said metering rod assembly is adjusted by adjusting a fluid pressure within said bladder to produce a force for urging said holder and said metering rod toward said outer surface of said applicator roll. 28. A method according to claim 1, said adhesive having a viscosity of 15-55 Stein-Hall seconds. 29. A method according to claim 1, wherein only 1-2 of said flutes are in contact with said applicator roll and/or said adhesive layer at one time. 30. A method of applying adhesive to flutes of a corrugated sheet, each said flute having a leading sloped face, a trailing sloped face and a crest therebetween, said method comprising the steps of: a) applying a layer of adhesive on an outer surface of an applicator roll and rotating said applicator roll in a first direction; b) moving said corrugated sheet along a path adjacent said outer surface of said applicator roll to apply adhesive to said flutes from said layer of adhesive; and c) initially contacting said flute with said applicator roll along said leading sloped face of said flute, thereby depositing glue on said leading sloped face; d) compressing said flutes down to 70-97% of their initial height against said applicator roll such that said trailing sloped face of each said flute is bent backward and shielded from contact with said applicator roll; and e) contacting said crest of said flute with said applicator roll thereby depositing glue on said crest. 31. A method according to claim 30, wherein
