1. A method for producing a gypsum board, the method comprising a step of continuously injecting a gypsum slurry into a gap between a pair of upper and lower lining paper sheets while continuously supplying the pair of upper and lower lining paper sheets to form a laminated material and allowing the laminated material to pass between a pair of upper and lower forming plates to obtain a molded body having a thickness depending on a space between the plates,
wherein a forming plate comprising: a plate main body constituted from an electrically conductive material; and an embedded electrode embedded in the plate main body, the embedded electrode being electrically insulated from the plate main body by an insulator and being embedded so as for a portion thereof to be exposed on a surface of the plate main body making contact with the lining paper sheet is used as at least one of the pair of upper and lower forming plates, a circuit is constituted by electrically connecting the plate main body and the embedded electrode embedded in the plate main body, and voltage is applied to the circuit, and when the lining paper sheet is cut to bring the plate main body and the embedded electrode into contact with the gypsum slurry and an electric current flows in the circuit, the space between the pair of upper and lower forming plates is expanded to remove a cause of conduction, and thereafter the space between the pair of upper and lower forming plates is restored to the original space. |
