Abstract
PURPOSE: To match the sectional contour of a wound core of a transformer to the inner diametral contour of a cylindrical coil bobbin thereby to increase the effective permeability and enlarge the magnetic flux, and simultaneously miniaturize the wound core and make the sectional contour thereof circular to increase the workability thereof.
CONSTITUTION: A cylindrical coil bobbin 2 which has been divided into two parts beforehand is press-fitted to a wound core 11 of a circular sectional contour wound with a band plate. Upon this occasion, since a gap 4' between the coil bobbin 2 and the wound core 11 is set as small as possible, the effective permeability and magnetic flux increase. The band material 12 corresponds to the inner side of the wound core 11 by a drive slitter device, and is small at the beginning and increases gradually and has a diameter corresponding to the central part of the wound core 11, and further corresponds to the outer side, and cut so that the diameter is reduced again.
