    Abstract: In this method of making corrugated board the board formed by the application of the liner to the single-face is passed between two metal surfaces, both heated to a suitable temperature. The temperature of the metal surface in contact with the liner is about the same as, or preferably somewhat higher than, the temperature of the other metal surface. In a corresponding apparatus the surface applying heat to the single-face is constituted by an endless moving metal belt, e.g. made of fatigue-resistant rolled spring steel.
