EXCITING COIL FOR INDUCTION HEATING AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To arrange an exciting coil near a heating roller and a heat-resistant belt not restricted in the contact part of the heating roller and the heat-resistant belt but in a range larger than that. SOLUTION: This exciting coil for induction heating has a curved-surface part 105a having curvature along the curved-surface shape of the heating roller 201, an extended part 105b extended from the curved-surface part 105a to the belt-in-side of the heating roller 201 and having curvature different from the curved-surface part 105a, and an extended part 105b extended from the curved-surface part 105a to the belt-out-side of the heating roller 201 and having curvature different from the curved-surface part 105a.
