Abstract:
1. A powder-rolling method comprising: a first step of supplying powder material to a circumferential surface of at least one rolling roll of a pair of rolling rolls; a second step, after the first step, in which a preliminary press roll provided in a different position from that of the rolling rolls presses the powder material which has been supplied onto the circumferential surface of a rolling roll, to the circumferential surface of the rolling roll; and a third step, after the second step, of inserting a sheet-shaped base material together with the powder material between the pair of rolling rolls, thereby attaching the powder material to the base material by pressure, wherein, in the second step, the preliminary press roll is moved so as to approach the circumferential surface of the rolling roll and to be separated therefrom, and wherein a predetermined load is applied to the preliminary press roll.
