  • Magnetic core blanks of magnetically permeable sheet material
    Patent number: 4839623
    Abstract: Magnetic cores are manufactured from blanks of magnetically permeable sheet material that have core preforms including strip elements that are partially separated from adjacent portions of the blank. Stabilizer strip elements are provided at opposite sides of the preform and are partially separated from adjacent portions of the blank. A tube is attached to one end of the blank and a weight to an opposite end of the blank. After removal of portions of the blank adjacent to the strip elements, the strip elements are wound upon the tube while tension is applied to the strip elements by virtue of the weight. After the winding, the strip elements of the core preform define a core configuration, and the remainder of the blank is removed.
