Abstract
The powder-rolling device (1) includes: a pair of rolling rolls (2) to attach powder material (Y) to a sheet-shaped base material (X) by pressure; a preliminary press roll (8) to press the powder material (Y) to a circumferential surface of a rolling roll (2) before the powder material (Y) is attached to the base material (X) by pressure; and a support device (10) supporting the preliminary press roll (8) movable, so that a load applied to the preliminary press roll (8) becomes equal to a set value which has been set beforehand.
Claims6
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.
A powder-rolling device comprising:
- a pair of rolling rolls to attach powder material to a sheet-shaped base material by pressure;
- a preliminary press roll provided in a different position from that of the rolling rolls and arranged to press the powder material which has been supplied onto a circumferential surface of a rolling roll, to the circumferential surface of the rolling roll, before the powder material is attached to the base material by pressure;
- and
- a support device supporting the preliminary press roll movable in a direction to approach the circumferential surface of the rolling roll and to be separated therefrom, said support device applying a predetermined load to the preliminary press roll.
A powder-rolling device comprising:
- a pair of rolling rolls to attach powder material to a sheet-shaped base material by pressure;
- first and second preliminary press rolls provided in different positions from those of the rolling rolls and each arranged to press the powder material which has been supplied onto a circumferential surface of a respective rolling roll, to the circumferential surface of the corresponding rolling roll, before the powder material is attached to the base material by pressure;
- and
- first and second support devices each supporting a respective one of the preliminary press rolls to be movable in a direction to approach the circumferential surface of the corresponding rolling roll and to be separated therefrom, said support devices each applying a predetermined load to the corresponding preliminary press roll.
