METHOD AND SYSTEM FOR PRODUCING SAND MOULDS

摘要

The method for the stepwise production and advancing of sand mould parts in a mould-string foundry plant comprising a station (1) for making mould parts, a pouring station (3) and a conveyor (2) for stepwise advancing of mould parts (101-109) from said station (1) for making mould parts towards said pouring station (3), includes the step of double indexing the mould parts using a first, moveable, part (21) of the conveyor. By double indexing the mould string, the time during which pouring into the moulds has to be interrupted can be reduced.
