Beschreibung
Zusammenfassung:	The subject matter of the invention is a process for production of a corrugated board using an aqueous adhesive which contains polyvinyl alcohol and clay, or polyvinyl alcohol, clay and a water-soluble boron compound. The concentration of the polyvinyl alcohol in the adhesive solution and the viscosity of the adhesive are as defined in the patent claim. The adhesive is applied having a temperature of 60 to 95 DEG C. The process of the invention is excellent in energy saving. The corrugated board can be manufactured at high speed without heating after application of the adhesive, which is easy to handle and has improved adhesion property.
