Abstract
PURPOSE: To prevent the crazing of resin coating film or its peeling from base material by roll-forming the coated steel plate while projecting heat medium thereto and heating the same to the specific temperature range.
CONSTITUTION: A steel plate 1 coated with resin paint of acrylic base, epoxy base or the like is un-coiled from an un-coiler 2 and is passed within a heater 3 of a far infrared ray projector or the like so that it is maintained at a temperature range of 50W100°C, thence it is fed into forming roll groups 4W9 and shear 10. When it reaches the specified temperature or lower during this time, hot wind is spouted through piping 12. Since this treatment lets the coating film resin maintain the stable deformation ability and the adhesiveness to base material, the production of cracks and the peeling from the base material do not occur and the formed product of good surface characteristic is formed.
