ABSTRACT:
A method for forming a magnetic core around a pre-wound wire coil involves: passing an end of a strip of magnetically permeable metal through the center of the coil and forming it into a loop encircling the wire coil through its center; revolving the loop to wind the strip onto the loop until it has the desired thickness of the magnetic core to be formed; retracting the strip from the coil to reduce its circumference and to draw it tightly around the coil to form the magnetic core; followed by severing the core from the retracted strip. Apparatus for the practice of the method is provided.
