Claim:
1. A method for producing a gypsum product, the method comprising: feeding a first sheet of paper on a conveyer belt; depositing gypsum slurry on the first sheet of paper; covering the gypsum slurry with a second sheet of paper; forming a gypsum panel; allowing the gypsum panel to set at least partially while the gypsum panel is moving on the conveyer belt; and scanning with a laser scanner at least one edge of the gypsum panel as it is moving on the conveyer belt and passes the location at which the laser scanner is located; wherein the laser scanner transmits scans to a processor, and the processor is equipped with a software which calculates an edge angle of the gypsum product and a deviation in the value of the edge angle calculated from a pre-specified value for the edge angle; and wherein if the calculated deviation is larger than a pre-specified value, the gypsum slurry is reformulated to even its distribution between the first sheet of paper and the second sheet of paper.
