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.

摘要： The invention involves a process for foam treating pile fabrics, especially carpets, by applying a foam composition through the backing of the fabric. The fabric is wrapped partially around the foam applicator at a wrap angle of at least 60 degrees, while the facing of the fabric is free of pressure. A foam applicator is also taught.

摘要： This invention relates to a foam applicator device for foam treating pile fabrics, especially carpets, by applying foam through the backing of the fabric. The device includes an applicator body containing a bore with injection ports and an applicator slot extending through a round applicator pipe, and an internal foam distribution pipe. The applicator pipe has a diameter of one to three inches in order that the backing of the fabric may be wrapped around said pipe.
