Abstract
In a process and a device for the impregnating and/or coating application of liquid, optionally foamed substances, through a slot the parts of the device performing the application are arranged to form a surface almost plan-parallel to the surface of the sheet material to be subjected to the application so that the trailing end of the application device is supported by the sheet material. Between the application device and the surface to be coated, a hydraulic pressure is generated which floatingly supports the device and which has a uniformizing effect on the application layer.
