PURPOSE:To perform efficient positioning work, by shifting a positioning device at every completion of half-circle 1a laminated plate piling, and pressing each laminated plate with a pressing method provided on contacting surfaces. CONSTITUTION:A steel plate 9 is put on a base plate 10, and contacted with the first wall 32 of a positioning device 6 by inserting. The first laminated plate a1 is formed, while, similarly, steel plates are piled one after another, and the second and the third laminated plates a2 and a3 are formed on the first and the second mounting surfaces 30, 31. Next, the positioning device 6 descends to arrow direction y1 by rotating a rotation drive. And then, a main surface of the third laminated plate a3 is pressed by the first contacting surface 33. On this condition, the fourth laminated plate a4 is formed by piling the steel plate 9 on the third laminated plate. Similarly, the fifth laminated plate a5 is formed on the fourth laminated plate for y1. An iron core stem 2 of approximate circular shape is formed. |
