Abstract

Ready-to-pour shells or core assemblies produced utilizing at least two in-line core shooting machines (1), each core shooting machine (1) having two, at least slightly differing sets of tools (4), each set comprising an upper tool (2) and a lower tool (3), and identical conveyor plates (5) serving, on the one hand, as the lower tool (3) of the first core shooting machine (1) and, on the other hand, as for transporting the core (6) or the core assembly along a transfer path (7) through the apparatus. For purposes of reducing floor space requirements with the use of a simple construction, the apparatus is designed and constructed such that, on the first core shooting machine (1), the operative tools (2, 3) of a first set of tools (4) are exchanged for tools (2, 3) of a second set of tools (4), after the conveyor plate (5) with the first core (6) thereon has left the first core shooting station, that on the second core shooting machine, the operative tools (2, 3) of the first set of tools (4) are exchanged for the tools (2, 3) of the second set of tools (4), after the conveyor plate (5) with the first and the second core (6) thereon has left the second core shooting station, and so on, until the exchange of the tools (2, 3) of the set of tools (4) to be substituted in the last core shooting station, so that a conveyor plate (5) accommodates cores (6) made exclusively with the same set of tools (4).
