Abstract
In a method for pouring several moulds in a mould-string plant in the pouring operation, the moulds are produced by compression of sand or similar mould material in a pressing chamber comprising pattern platesfor providing impressions in the surfaces of the mould parts for forming the mould cavitiesand inlet runners. The moulds are advanced to a pouring track or guideway, on which the casting moulds are formed by positioning the mould parts close together and the advancement of the casting moulds is stepwise through a pouring station, in which the moulds are filled with molten metal. By providing at least one runnerfor mutually connecting at least two inlet runnersfor consecutive mould cavities, the mutually connected mould cavities can be filled through a single pouring inlet, and unused pouring inletsmay be plugged by a suitable plugin order to minimise the amount of molten metal needed to fill the mould cavities
