Abstract (en)
[origin: EP0928845A2] Before the dryer (26) there is a unit (30, 32, 34) moistening and/or heating the web (16) and/or the coating material (20) or the layer coated (24). An Independent claim is included for the corresponding coating method. Preferred features: The moistening and/or heating unit produces and/or supplies vapor, especially water vapor or steam. It may spray fluid, especially water. The moistening and/or heating unit is located immediately ahead of the coating location. The unit delivers vapor or a spray of mist towards the coating location. It includes a steam supply line (36) with openings (36a) directed appropriately. Nozzles and/or wall sections used, taper in the outlet direction. The unit is located behind the coating location. It is located before or after a device leveling and/or metering the coating layer. It directs steam or liquid spray perpendicular to the web. It has a steam supply line (32a, 34a) with steam outlets facing the web. Steam outlets extend over a distance of 0.1-200 cm, preferably 50-100 cm. A series of steaming or spraying sections reach across the web, each individually controlled. A suction unit (40) is included, behind the moistening unit. When using a leveling- and/or dosing unit (22) the suction unit is connected to a coating medium interception unit (22d).
