摘要
An installation for impregnating a porous substrate by transfer of powder, including an area for storing the powder, and an endless conveyor capable of being moved, which includes an external surface containing cavities. The external surface of the conveyor delimits an edge of the storage area to fill said cavities with the powder. The installation comprises a positioner for holding the porous substrate in contact with a fraction of the conveyor length, to seal cavities containing the powder. A drive device enabling to move the conveyor and the porous substrate, and means for displacing the powder are arranged opposite said fraction of the conveyor length, to at least partly displace a portion of the powder across the porous substrate.
