    Patent number: 10589347
    Abstract: The sand moulding machine (1) includes a moulding chamber (2) formed by a chamber top wall (3), a chamber bottom wall (4), two opposed chamber side walls and two opposed chamber end walls (7, 8). A chamber wall is provided with a sand filling opening (9) communicating with a sand feed system (10). At least one of the chamber end walls is provided with a pattern plate (12, 13) having a pattern (14, 15).
