Claims19
A method for coating a workpiece, the method comprising:
- a) supplying humid air to a coating assembly, the coating assembly comprising:
- an applicator head;
- and
- a shroud comprising a housing defining an internal cavity, the housing comprising:
- a top plate;
- a first side plate extending downward from the top plate;
- a second side plate extending downward from the top plate;
- and
- the first side plate being opposite the second side plate;
- a first axis A-A intersecting the first side plate and the second side plate;
- whereby the applicator head is at least partially disposed inside of the internal cavity and the humid air is supplied to the internal cavity of the coating assembly;
- b) conveying the workpiece on a conveyor configured to support the workpiece along a machine direction MD such that the conveyor and the applicator head move relative to each other, the machine direction MD being parallel to the first axis A-A of the shroud, while the workpiece is positioned between the first side plate and the second side plate;
- and
- c) directing a coating composition onto a surface of the workpiece using the applicator head and exposing the surface of the workpiece to the humid air;
- wherein during step a) the shroud is in a first state and wherein prior to step a) the shroud is in a second state, wherein in the second state the applicator head is located outside of the internal cavity.
