Abstract

PURPOSE: To simplify the method for manufacture of the core for transformer by laminating a silicon steel plate punched out to form E shape and by immersing adhesive from the rear wherein the plate is split to obtain the required thickness and the end of its leg is ground.
CONSTITUTION: E shaped cores 1 are laminated a chute 2 by placing the back of the cores upwards and are properly clamped by a standing piece 3. With adhesive applied to the surfaces of the cores 1 by a roller 4, adhesive is immersed between the cores and the spaces of the back a of the cores is completely adhered. Adhesive is also properly immersed into legs c, d and central legs e etc. to adhere them. Then, the cores are split into block X properly, and are clamped by a frame 5. The ends of each leg is ground by polishing cloth 7 etc. In this composition, adhesive is not adhered to the sides of frames when the cores are installed to a spool and are completely set, the force of adhesion of the legs is reinforced by the heat at the time of polishing the ends and high quality cores are easily obtained.
