What is a corrugating machine?

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.

How does a corrugation machine work?

The Corrugator

A corrugator is a set of machines designed to bring together three, five or seven sheets of paper to form single, double or triple wall board in a continuous process.

The 3 key stages:

* Corrugating the flutes and gluing to a single liner

* Gluing the outside liner to make a rigid board

* Cutting the board to the desired size

Three sheets of paper (containerboard) are unrolled simultaneously on the corrugator: the inner liner, the outer liner and in the middle, the medium (also called fluting).

The medium sheet is given a "wave". This corrugation is obtained by pressing the sheet under heat through grooved metal rolls. This operation gives the paper its fluted shape in the single facer.

Starch is applied to the tips of the flutes on one side, the outer liner and the inner liner are glued to the tips of the corrugated medium sheet of paper from the outer and the inner side respectively.

The Corrugated board comes out of the corrugator as a flat board sheet.
