Abstract
A method of processing perforated gypsum boards is disclosed. When the gypsum boards have been perforated the following steps are performed while the boards are being moved individually along a path. The moving boards are sprayed with pressurized water which is directed towards the opposite surfaces of the boards so as to enter apertures or slots formed by the perforation of the boards, and then water is removed from the moving boards by blowing pressurized air against the boards and sucking water therefrom, wherein dust on the boards is entrained into the water and removed from the boards together with the water.
