A method of applying adhesive to flutes of a corrugated sheet includes th e steps of applying a layer of adhesive on an outer surface of an applicator roll, rotating the applicator roll, and rotating a web positioning roll adj acent the applicator roll. The web positioning roll and the applicator roll each have rotational axes and define a gap between respective outer surfaces thereof. The corrugated sheet is moved along a path adjacent the outer surf ace of the applicator roll to apply adhesive to the flutes from the layer of adhesive. A control system is utilized to automatically maintain the rotati onal axes substantially parallel to one another. In other examples, the cont rol system can automatically maintain a desired width of the gap, maintain a desired pressure to be applied to the flute crests, and/or automatically de termine flute height.
