ABSTRACT:
The system includes two platforms vertically movable along guides provided on a fixed support. A top platform is swingable between a horizontal position in which it superposes a lower platform, and a vertical position. A blowing plate is positioned on the top platform. The system is provided with a double catch which is selectively engageable with the bottom wall of the top platform when the latter is in the horizontal position, and with the fixed support when the top platform is in the pivoted-away position.
