Title:
FORMING METHOD OF STRIP-FORM BODY
Document Type and Number:
Japanese Patent JPS5550924
Kind Code:
A
Abstract:

PURPOSE: To obviate giving adverse influence to the size in the thickness direction of moldings such as coils, etc. of electrical machinery and apparatus by providing chipped-off parts at the corner of a strip-form body and edgewise bending the body with said chipped-off parts being put on the inner side.

CONSTITUTION: At the time of forming a strip-form body 1 to a rectangular section through drawing, tapered chipped-off parts 6 are added to a corner part 2 to its rectangular section. With the chipped-off parts 6 being put on the inner side 41, the strip-form body 1 is bent edgewise in the width direction. Since the chipped-off parts 6 are formed so as to conform to the bulge produced at the bending, the size of the buldge part in the thickness direction does not become larger than the thickness A of the strip-form body 1 and becomes the size that can be contained readily in the slot even if the body is formed to multistage-form coil, etc. This method enables the surplus jobs such as filing and others to be saved.
