Abstract
A method and an apparatus for replacing pattern plates in a moulding plant for making boxless mould parts of sand or other like material is characterized by the use of a revolving table (1), which is provided with e.g. four symmetrically placed arms (1), in which are suspended pattern plates (2,3). The revolving table is designed for sequential conveying of the pattern plates (2,3) for placing these on a squeeze plate (PP) and a counter-pressure plate (MTP), respectively, in the moulding chamber of a moulding plant (suggested only on the drawing). The pattern plates (2,3) are placed in the respective arms (1) when the latter are just opposite the changing position. From the changing position, the pattern plates (2,3) are conveyed into a moulding chamber by a transverse sliding movement in an essentially known manner.
