ABSTRACT:
This method and apparatus provide for uniformly coating a hot elongate member with a powder coating. The elongate member and power carry an electrostatic charge which aids in providing the uniform powder coating. This method and apparatus electrostatically charge and heat the elongated member prior to entering a powder coating booth. In the booth, we sequentially discharge the powder coating, electrostatically charge the powder coating and then coat the elongated member with the charged powder coating. In one development, this method and apparatus uniformly powder coats window lineals directly on a pultrusion line.
