<p>The concrete molding system for production of artificial stones involves a movable rectangular hopper (4,6) with its interior space (7) filled with concrete. Rectangular molds (3a,3b) are slightly overfilled with concrete. The rectangular molds are separated by straight vertical walls (2). The mold plate may move on rails (8) over a flat floor plate (9). The hopper frame has a scraper edge (5) sliding over the top of the mold plate.</p> |
