ABSTRACT:
A coil form with a coil support and with a winding applied thereto, whose turns are provided with a coil bond material. The bond material contains a volatile solvent and mutually fixes the turns when dried (in a dry state). To guarantee an essentially uniform, nearly solvent residue-free drying of the coil bond in the entire winding even in the case of a very large number of coil layers, the coil support is a porous coil support having open pores. The coil support has a diffusion coefficient with respect to the solvent that is equal to or slightly lower than that of the winding.
