Corrugator Machine-Corrugated Board Making Machine

A corrugator machine 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 machine 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.

The corrugator machine is the largest and most expensive machine in the corrugated fiberboard manufacturing process. It is about the length of a football field and can cost several million dollars. The corrugator combines rolls of linerboard and medium into sheets of corrugated board. The typical corrugator is equipped to run both single wall and double wall in a variety of flute heights. Modern machines can also be equipped with innovative enhancements that offer a range of value added features such as functional coatings, color coating, tear tape or internal strings, and water resistant adhesives. Advanced technology such as razor cutting knives and robotic scoring heads allow the machine to produce quality board with faster set ups and shorter cut offs.
