    摘要: The present invention relates to a method of applying adhesive to corrugating media to produce corrugated materials by foaming the adhesive with air prior to application to the flute tips of the corrugating media. The foamed adhesive requires less precise control of the applicator rollers, and remains in place on the flute tips, rather than migrating into the flute valleys. As a result, the same volume of adhesive can be used with decreased solids content, decreasing overall adhesive cost and increasing corrugator productivity. In addition, because of the more precise placement of the adhesive on the tips of the flutes, a stronger, higher quality board can be produced. The adhesive can be starch-based, and can be foamed by a variety of methods, such as in existing pin-rotor stator containing foaming machine used for foaming latices.
