A complete corrugator line consists of roll stands, preheaters, single facers, overhead bridge, glue machine, double facer, slitter scorer, cut off machine and auto down stacker, it will also require service supplies from boiler, starch kitchen, air compressors and waste management. Production stars by paper being loaded onto the roll stand, the paper is then heated/ steamed and passed into the single facer, where the flute is formed ad liner paper glues to the flute tips, the single faced web is then transported via the overhead bridge and then heated once more prior to entering the glue unit. Starch/glue is then applied to the bottom flute tip and passed with a bottom liner into the heated double facer. The forming and bonding process is complete on existing double backer by heating and cooling system to from corrugated boards. The board then passes through slitter scorer and cut off machine, where is slit and cut for the required sheet size. These sheets are then stacked in the down stacker and ready for distribution throughout the factory.
