Abstract
Provided is a method for continuously forming a synthetic stone having a thickness with a high degree of accuracy, without using a complicated apparatus, in which resin compound is filled between belt-like upper and lower films in two layers running horizontally on a band-like floor, upstream thereof, so as to continuously form the synthetic stone, a regulating plate 31 is disposed above the band-like floor 3 and downstream of the resin filling part, and the resin compound (R) is continuously filled in a condition in which the gap between the regulating plate and the band-like floor 3 and is set to a predetermined value. Further, the filling volume of the resin compound is adjusted in accordance with a variation in the thickness of the formed resin plate having passed through the regulating plate.
