Corrugator
Also: corrugator, corrugating machine
The machine that forms corrugated board by fluting the medium, applying starch adhesive, and bonding it to the liners in a continuous process.
A corrugator is typically 80 to 130 m long. Reels of medium pass through corrugating rolls that form the flute shape under heat and pressure. Starch adhesive is applied to the flute tips; the medium is then nipped to the liner on a heated bonding platen. Modern corrugators run at 300 to 400 m/min.
