Abstract
A manufacturing method and apparatus of an organic resin coated metal sheet is provided. Temperatures of edge portions of the metal sheet and a temperature of an approximately central portion of the metal sheet are respectively measured using a metal-sheet temperature measuring device arranged directly upstream of lamination rolls. Respectively measured temperature values are inputted to a heating temperature controller, and output values calculated by the heating temperature controllers are inputted to a metal sheet center portion heater and the metal sheet center portion heater, respectively, to control the heating of a widthwise approximately center portion and edge portion, respectively, to a first and second temperature, respectively, the second temperature being higher than the first. A resin film is extruded to pre-rolls and is sandwiched and pressure-bonding to the metal sheet between a pair of lamination rolls. Resin portions projecting from both edge portions are then removed.
