Abstract
The present invention relates to a single facer, which comprises a humidifying and heating unit placed on the upstream side of an air pressurization corrugating mechanism for humidifying and heating a corrugating medium and a feed mechanism for supplying the corrugating medium, processed by the humidifying and heating unit, to the air pressurization corrugating mechanism at a given speed. The corrugating medium is supplied at the given speed after the humidification and heating process for the corrugating medium, so that an air pressure to be taken at the corrugation is reducible and a predetermined flute configuration is maintainable. In addition, the spring back of the corrugating medium hardly occurs, which makes it possible to manufacture a corrugated fiberboard sheet with a high shock absorbing ability.
