Patent

CA 2273566

A method and apparatus for producing a single face corrugated web in which a steam cloud is injected between the corrugated medium web and the liner web directly at the line along which the webs converge. This type of steam injection allows faster corrugator speeds without sacrificing bonding quality. An adhesive slurry of water and starch granules is applied to the flute tips to form glue lines on the corrugated web prior to the convergence of the webs. The injected steam cloud directed at the web convergence line adds heat without promoting premature dehydration to facilitate proper conditions for effective cooking of the adhesive slurry to thoroughly gelatinize the adhesive. In some applications, dry steam is preferred because dry steam does not significantly interfere with subsequent dehydration of the adhesive gel during the formation of the initial green bond.
