Abstract
A device for coating a web of material, especially a web of paper or cardboard, that travels around a backing roll, with a coating roll that scoops liquid coating from a chamber and demarcates in conjunction with the backing roll a coating nip, and with a flow-control system including a final flow controller and an initial flow controller upstream thereof in the direction that the web travels in and demarcating in conjunction with the backing roll an initial flow-control nip. The device has a non-resiliently supported initial flow controller that extends into the vicinity of the coating nip and demarcates it in the form of a chamber at the outlet end, whereby the initial flow-control nip remains open to the backing roll and to an outflow channel to the coating roll.
