Apparatus for directly applying a liquid or pasty medium onto a moving paper or board web. A flexible endless loop rotating belt is supported by guide rolls in the loop. A shoe in the loop has a convexly curved surface over which the belt is guided and the web is carried over the belt as it passes the guide surface of the shoe. Toward the upstream end of the shoe, a predosing apparatus applies a medium to the web. Toward the downstream end of the shoe, a final dosing blade doses the medium applied to the web. The shoe has a region, at least at the upstream region thereof, the cross-sectional profile of which is adjustable, and that adjustment is enabled section by section zone-wise across the width of the web. |
