Abstract:
A method of advancing moulds, said moulds being in the form of closely juxtaposed moulds with castings in mould casting cavities at mainly vertical parting surfaces between successive moulds, said closely juxtaposed moulds constituting a mould string in which each mould occupies a given length in the longitudinal direction of the mould string, said method comprising the steps of:moving the mould string on a precision conveyor; andthereafter transferring the moulds of said mould string to a second conveyor, wherein said transferring step comprises, each time said second conveyor receives a mould from the mould string, the steps of (a) advancing the second conveyor in a controlled manner through a greater distance than the length of each mould received from the mould string, and (b) stopping the second conveyor when it has advanced said greater distance so as to produce an interspace on the second conveyor between consecutive moulds:wherein said precision conveyor is moved and said second conveyor is advanced synchronously during said transferring of said moulds; andwherein the advancing of said second conveyor is terminated later than the moving of said precision conveyor in order to create the interspace.
