A corrugator is a large machine, made up of a series of smaller machines, that combines two different kinds of paper to create cut sheets of corrugated fiberboard. The flat, facing sheets are referred to as the liners, and the wave-like, fluted layers are known as the corrugating medium, or simply medium.
The corrugator takes large rolls of paper produced on paper machines, flutes the medium and glues it to the liners, one at a time, and delivers stacked, cut, and scored sheets of corrugated board to various converting machines. The converting machines convert the sheets of corrugated board into “box blanks,” which are ready to be made into boxes, and other corrugated board products.
