A method of progressive processing includes feeding a strip-shaped sheet to a press machine; pressing the strip-shaped sheet with the press machine; and joining the strip-shaped sheet with a new strip-shaped sheet by applying a tape over an end of the strip-shaped sheet located in a direction opposite a direction in which the strip-shaped sheet is fed and an end of the new strip-shaped sheet located in a direction in which the new strip-shaped sheet is fed.

Progressive processing method

A method of manufacturing a stator core includes punching out core members from an electrical steel sheet in three rows arrangement side by side along a width direction of the electrical steel sheet. Each of the core members has connecting projections. The connecting projections project radially outward from an outer periphery of the core member. The punched out core members are stacked to form the stator core. Each of the core members in two of the three rows arrangement have a connecting projection angled at a first angle from the width direction of the electrical steel sheet. Each of the core members in a third row having a connecting projection angled at a different second angle from the width direction of the electrical steel sheet.
