Abstract: A travelling slot cutting machine and method of cutting a workpiece upon the machine in which there are two independently operable and longitudinally aligned, endless conveyor belts, the adjacent ends of which are spaced apart to define a gap through which a cutting medium may be directed. To cut a workpiece supported over the gap, the cutting medium is directed through the gap while the cutting machine, as well as the gap, are moved longitudinally relative to the stationary workpiece. In moving the gap, the conveyors are clamped against movement over their respective supporting rollers. The supporting rollers are then moved in such a fashion that the length of at least one of the conveyor belts is maintained unchanged as the workpiece is transported from the upper run of one of the conveyor belts to the upper run of the other conveyor belts.

Abstract: A foundry molding machine is disclosed wherein a core or mold is molded from moldable material such as sand in first and second mold boxes having a cavity. The cavity is filled with the sand and is then cured to form the mold. The first and second mold boxes are separated so that the mold remains in the first mold box with a downwardly facing cavity. Any of several means may be used to assure that the mold remains in this downwardly facing cavity. A transfer conveyor is then moved to a position closely beneath the mold. The first mold box is then moved upwardly as ejection means acts on the mold to eject it downwardly onto the closely spaced transfer conveyor. The transfer conveyor then moves out from underneath the first mold box to remove the completed mold and the cycle repeats.
