因となっているためである。[0012] Paste filling was performed using the paste filling apparatus according to the present invention shown in FIG. 1 and a conventional paste filling apparatus as shown in FIG. 3, respectively, and the variation in the amount of paste filling and the variation in the filling density were compared. . Using a paste having a paste density of 4.1 g / cc, the grid was filled with 160 g of filling amount based on the filling amount. FIG. 4 shows the results. As is clear from the figure, the dispersion of the filler according to the present invention is reduced, and when compared by the σ value, it is 0.551 g in the present embodiment, compared with 3.07 g in the conventional example.
/ 6. In addition, it can be seen that the variation according to the conventional example has a periodic variation. This is because the cycle of the paste application pressure fluctuation of the blade 1 to the filling roll 2 is coincident, and the fluctuation of the application pressure causes a variation in the filling amount.
