Abstract: A press for manufacturing stones 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 converyor for supplying empty product plates and with a discharge conveyor for discharging the product plates carrying stones shaped in the mould, whereby 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, whereby 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 and next the stones shaped in the mould are pressed out of the mould

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.

Abstract: Device for manufacturing stones, provided with a frame, with a mould having boundary walls defining moulding rooms inside the mould, with a stamp movable up-and-down arranged above the mould and with a table arranged under the mould. Filling pieces are movable between a first position, in which they are located under the mould and whereby, see in top view, at least parts of the filling pieces project from the walls for forming recesses, and a second position, in which the filling pieces are located beside the mould, seen in top view. Extensions are connected to the filling pieces, those extensions being movable forward and backward and co-operating with guide means for guiding the filling pieces, whereby the extensions project from the mould in the first position.
