Corrugator Lines

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.

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). Corrugated fiberboard can be specified by the construction (single face, singlewall, doublewall, etc.), flute size, burst strength, edge crush strength, flat crush, basis weights of components (pounds per thousand square feet, grams per square meter, etc.), surface treatments and coatings, etc.
