Heating device for drying paint layer, has coil surrounding metallic band zone transversally to longitudinal direction of band, including single concave loops whose average plan is orthogonal to longitudinal direction of band
Heating device for drying paint layer, has coil surrounding metallic band zone transversally to longitudinal direction of band, including single concave loops whose average plan is orthogonal to longitudinal direction of band
The device has a choke coil (B) surrounding a zone of a metallic band (A) transversally to longitudinal direction (D) of the band. The coil has a set of single concave loops (1) whose average plan (P) is orthogonal to longitudinal direction of the band. The loops are arranged in parallel or series among themselves, where each loop has two larger and smaller sides in relation to width and thickness of the band.
