為の粉末供給口ｅを有するホッパｆを構成する。[Prior Art] FIG. 3 shows an example of a conventional powder rolling apparatus, which is a pair of rolls a which are parallel to each other and rotate at appropriate intervals.
Are arranged horizontally, above the rolls a, a pair of left and right side plates b as viewed from the rolling direction, and from the rolling direction extending between the side plates b and extending in the width direction of the roll a. By seeing and fixing the pair of front and rear guide plates c, a hopper f having a powder supply port e for supplying the powder d is formed between the lower ends of the respective guide plates c.

す。In the figure, g is a green sheet formed by a roll a, and h is a cylindrical surface-shaped entrapment angle adjusting plate for moving along the outer periphery of each roll a to adjust the entrapment angle of the powder d. .

てグリーンシートｇに成形される。Thus, after the powder d is stored inside the hopper f, the rolls a are rotationally driven so that the facing portions rotate downward, so that the powder d inside the hopper f passes through the powder supply port e. The powder d flowing between the rolls a under the f and flowing between the rolls a is rolled by the rolls a to be molded into a green sheet g.

Since there was no means for adjusting the state, the properties of the powder d introduced into the hopper f, such as hardness,
When the particle size, shape (spherical shape, flake shape, irregular shape), particle size distribution, etc. changed, the green sheet g could not be formed.

ができなくなる虞れがあった。Further, since there is no means for adjusting the amount of the powder d supplied from the powder supply port e of the hopper f to the upper side between the rolls a, for example, rolling by each roll a in order to improve productivity. When the speed is increased, the flow of the powder d from the powder supply port e cannot keep up with the rolling speed by the rolls a, and the powder d accumulated on the upper side between the rolls a.
There is a risk that the normal amount of the green sheet g cannot be formed and the normal green sheet g cannot be formed.
