ABSTRACT:
For a production of foundry moulds, dies are stepwise, cyclically conveyed by a continuous conveyor and, synchronously with the dies, shot hoods are conveyed into a shot station which is common to both the dies and shot hoods, with the shot hoods being displaced with respect to the dies. For this purpose, a cyclically revolving die conveyor is provided for the dies, and a further conveyor is provided for the shot hoods, with the further conveyor revolving synchronously with the die conveyor. At least one shot station may be provided which is common to several dies and may be associated with the die conveyor in which dies and the associated shot hoods are conveyed by the die conveyor in a reciprocally displaced manner.
