Claims
- 1. A method for coating sheet metal which comprises unwinding the sheet metal from a coil thereof and directing the sheet metal through a series of rollers, one or more of which is an applicator roller, placing a liquid resinous coating composition in a paint pan, rotating a roller in the pan and picking up said resinous coating composition and transferring it to an applicator roller; thenceforth to the moving sheet metal, and distributing discrete masses of material uniformly on the liquid coating and causing at least a portion of them to submerge at least partially in said liquid coating, and drying said liquid coating.
- 2. The method of claim 1 characterized further by distributing the discrete masses to form a discontinuous field coextensive with the area of the coating.
- 3. The method of claim 1 characterized further by distributing discrete masses of material which protrude above the surface of the coating.
- 4. The method of claim 3 further characterized by rewinding the sheet metal after the drying step into a coil.
- 5. The method of claim 1 wherein the discrete masses are coating powder precursor chips.
- 6. The method of claim 4 characterized further by pulling a backer sheet from an unwinding coil thereof and interleaving it with the coated sheet metal as the metal is rewound.
