Version. In a conventional processing facility such as a continuous cutting device for processing a metal web into a sheet-shaped product, a sheet-shaped product having a predetermined shape with a plurality of holes drilled from an unprocessed metal web is obtained. The following method was adopted.

That is, the first method is performed by installing a facility for rewinding a metal web from a web roll and cutting it into a sheet of a predetermined length and a single-wafer punching machine for punching the sheet on separate lines. In the second method, cutting equipment for cutting a wide metal web to a predetermined width and equipment for punching the cut metal web and cutting it into a predetermined width are installed on separate lines for processing.

Furthermore, the third method is to perform drilling, cutting to a predetermined width, and cutting to a predetermined length by installing each equipment on the same line, but in this method, a free loop is provided in the middle of the processing process. The metal web is intermittently supplied to the next process equipment.

In the first and second methods, since processing is performed using a plurality of lines, there is a problem that a step of carrying between the lines is required, and also in the third method, the metal web is intermittent. However, there is a problem that it is not continuously processed, and productivity is poor.
