Title: A METHOD IN PROCESSING GYPSUM BOARDS OR TILES
Abstract:
The invention relates to a method in processing perforated gypsum boards (G). When the gypsum boards have been perforated the following procedural 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 baords 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, dust on the boards being entrained into the water and removed from the boards together with the water.
