Beschreibung
Zusammenfassung:	An apparatus for coating foils, tapes with viscous solutions, comprising a guide member for the support to be coated, a wedge-type casting device as preliminary coating means and a striplike partition in the direction of movement of the support, forming a gap with a support extending over the width of the web. That partition now is serving as final coating means and is arranged between two chambers at different pressure, wherein the preliminary coating means is arranged just before partition. The housing of the preliminary coating means has a construction in the region of the flow slots extending over the width of the web. The flow slot is open in the vicinity of the overflow of the wedge-type casting device.
