<p>A metal strip (4) is continuously coated with a thermoset resin based paint by passing it through a pre-heating furnace (5) wherein it is raised to a pre-heat temperature of from 100 to 210 DEG C, then through a coating applicator (6) wherein a solid, substantially solvent free block (11) of the paint composition is pressed against the strip (4) at a substantially constant pressure of from 10 to 100 kilopascals to cause a liquid layer (13) of the paint composition to be deposited on the strip, then through a roll type smoothing device (18) to smooth and spread the layer and doctor it to thickness, then through a curing furnace (8) to thermoset the layer, and finally through a quenching bath (9). <IMAGE></p> |
