Abstract (en)
[origin: US4836134A] A device for coating a web of material that travels around a backing roller, with a coating chamber that opens toward the backing roller, and with a liquid-coating intake that has an overflow gap at the paper-intake end and is closed off by a metering unit at the paper-exit end. The coating device allows establishment of a wider range of coating densities (e.g. 4-20 g/m2) without great expenditure and without coating defects in the coating. The metering unit accordingly pivots independently of the coating chamber (3) around an axis that parallels that of the backing roller and is sealed off by a sealing structure (12) from the structure (6) that demarcates the coating chamber.
