Abstract

The first (6) of the steel bands is movable along a vertical convexly curved surface (8), whilst the second (7) is pressed against the first by two rollers (2,5). The bands are perforated. - The curved surface has suction boxes (9), and on the rear side of the second band are water-deflecting fillets (10).
