Abstract
A gypsum board forming device () constitutes an apparatus of producing gypsum boards. A layered formation of a lower sheet (), an upper sheet () and a gypsum slurry () passes through a forming gate (). The forming device forms the formation into a plate-like configuration with use of upper and lower plates (). The upper plate () is constituted from a fixed substrate plate () and a movable plate (), and the movable plate is in surface-to-surface contact with the upper sheet of the layered formation. A plurality of actuators () is supported by the substrate plate. Each of the actuators applies an upward or downward load (P) to the movable plate locally for a local deformation of the movable plate owing to a deflection thereof. A gate size (T) is locally changed by displacement of the movable plate relative to the substrate plate.
