Abstract: A method of advancing molds (5), after pouring to form castings (9) in the casting cavities (8), leaving a foundry plant comprising a mould-making station (A, 1-4) and a pouring station (B,7), the molds (5) leaving the plant in the form of closely juxtaposed mold parts (5) with the castings (9) in casting cavities (8) at the mainly vertical parting surfaces between successive molds (5), the latter constituting a mold string (F), in which each mold (5) occupies a given length (S) in the longitudinal direction of the mold string (F), the latter after having passed a precision conveyor (6, 16) being transferred to a second conveyor (10, 16, D).

Abstract: A method and apparatus of forming a plurality of moulds in a string system is provided by squeeze plates which compress the particulate mould material. One of the squeeze plates is pivotable so that when a pair of squeeze plates are compressed by particulate mould material, the pivotable squeeze plate may be pivoted out of the way to provide a string mould system. In another embodiment of the invention the pivotable squeeze plate is movable laterally to provide bilateral pressing of both of the squeeze plates.
