The most noteworthy thing about the present invention is that the double-double drilling device consists of a feeding machine, a winding machine, a drilling stand, and a drilling machine (see Figure 1), which allows for accurate positioning of thin plates and multiple drilling machines. The reason lies in the fact that Komei is structured so that it can be processed continuously by stacking the sheets one on top of the other.

The feeder is a device that continuously feeds a plurality of continuous long thin plates such as printed wiring boards to the plate and processing machine using a group of rollers. The roller group has rollers for winding each thin plate, and the number of rollers is the same as the number of thin plates.

Further, the winding machine is a device that winds up a processed thin plate as a continuous long piece. The winder also has the same roller group as the feeder.

Further, the above-mentioned drilling stand is disposed between the above-mentioned feeding machine and the winding machine, and is a device for positioning and processing the thin plate.
