Method for continuously forming a synthetic stone
First Claim
1. In a method for continuously forming a synthetic stone, comprising the steps of:
- filling a resin compound between two belt-like upper and lower films running horizontally in two layers; and
thereafter hardening the resin compound;
the improvement whereinafter the resin compound is filled between the film in two layers, the resin compound is passed through a pair of rollers guiding the belt-like films whereby the thickness of the resin compound is regulated; and
after passing through the rollers, the resin compound is passed through a rigid regulating plate disposed downstream of the rollers whereby pressure variation in the resin compound being fed is suppressed and the resin compound is formed into a plate-like shape, having a constant thickness, and wherein the lower film slides on a band-like floor, and wherein said regulating plate is supported by support rods that have adjusting members incorporated therein, and wherein the adjusting members are adjustable in order to maintain or adjust a gap between said regulating plate and said band-like floor.

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.
