ABSTRACT:
Method for manufacturing stones in a press provided with a mould including several moulding rooms and taking a fixed position, a stamp arranged above the mould and being movable up and down, a table arranged under the mould and being movable up and down, a supply conveyor for supplying empty product plates and with a discharge conveyor for discharging the product plates carrying stones shaped in the mould. The moulding mass is compressed in the mould while under the mould a moulding plate supported by the table is located, which is provided with upright ribs for shaping bevelled edges on the stones. During compression the stamp is moved downward until the stamp is located at a certain distance from the table, determined by cooperating stops provided on the table and on the stamp, after which the moulding plate is removed from between the table and the mould, while simultaneously a product plate is moved between the table and the mould. Next the stones shaped in the mould are pressed out of the mould by moving the stamp and the table simultaneously downward while maintaining the desired distance between the table and the stamp by means of the stops.
