C Flute Corrugated Cardboard Making Machine

Introduction

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.

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. The corrugated fluting medium with one liner attached to it is called single face web and travels along the machine towards the double backer where the single face web meets the outer liner and forms a continuous web of single wall rigid corrugated board, which is then cut to length and width and stacked.

Afterwards, the corrugated cardboard can be processed to corrugated cardboard boxes. The type of cardboard box depends on the type, shape and weight of the cargo, and the type of corrugated cardboard is decided by the cardboard box required. For light cargo, it does not needs too many layers or it will increases the weight of loaded cargo. For heavy cargo, the firmness of corrugated cardboard must be considered first. It is important to choose the most suitable type of corrugated cardboard.
