摘要： 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.

摘要： 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. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

摘要翻译： 公开了一种铸造成型机，其中芯或模具由具有空腔的第一和第二模具箱中的可模制材料（例如砂）模制而成。 空腔充满砂子，然后固化形成模具。 第一和第二模具盒被分离，使得模具保持在具有面向下的腔体的第一模具箱中。 可以使用几种方法中的任何一种来确保模具保持在该向下面向的腔中。 然后将转移输送机移动到模具附近的位置。 然后，随着喷射装置作用在模具上，将第一模具盒向上移动，将其向下推出到紧密间隔的传送输送机上。 然后，输送输送机从第一模具箱的下方移出，以移除已完成的模具并重复循环。 上述摘要仅仅是一般应用的简历，不是所有操作原理或应用的完整讨论，并不被解释为对所要求保护的主题的范围的限制。
