METHOD FOR SHARING A RING core of ferromagnetic material for a deflection unit deflecting FOR TELEVISION AND TUBE WITH A RING CORE SHARED BY SUCH A METHOD.

摘要

A method of severing an annular core (9) of a ferromagnetic material in which the annular core (9) is weakened by providing two lines of recesses (13) by means of a laser (10), as a result of which the annular core (9) is severed into two parts according to the provided lines of the recesses (13).
