Abstract
Systems and methods for forming corrugated boards are disclosed. The system includes a single face unit configured to form a single face board having a fluted layer and an outer liner. The system also includes a single face buffer configured to store or hold a length of the single face board. The system has a glue station configured to attach a second outer liner to the single face board to form a single wall board. The system also has an ultrasonic unit configured to apply ultrasonic vibrations to the single wall board. The ultrasonic vibrations are configured to remove moisture from the single wall board, activate, heat, and/or dry an adhesive used to attach the fluted layer and the outer liners, and/or cause the fibers of the fluted layer and the outer liners to weave, intertwine, or otherwise stick together.
