Abstract (en)

[origin: WO8808341A1] The device comprises a chamber (1) for an abrasive powder, two pairs of mechanisms (2, 3, 4, 5) for consolidating the powder, which are placed one under the other, means for feeding the abrasive powder into the chamber (1) and valves (12, 13) for discharging the worked-out powder. The device further comprises a system of channels (14, 15, 16, 17, 18, 19) for separately charging the abrasive powder (38) into the space (A, B) between the working organs (6, 7) of the mechanisms (2, 3 and 4, 5) for consolidating the powder and the plane (8) of transportation of the strip (9), as well as a system of channels (21, 22, 23, 24, 25) for separately discharging the powder (38) from said space (A, B) to the valves (12, 13) for discharging the powder from the chamber (1).
