Abstract

A method for securing the end sections of an annular laminated article, such as a stator core, which includes a plurality of serially joined sections, each section formed of a plurality of stacked, planar laminas. The article is initially manufactured in a liner form, and is then formed into an annular form with the end sections disposed adjacent one another. At least one tab associated with one of the end sections is displaced by a forming tool into a corresponding cavity of the other of the end sections to secure the end sections together. In another embodiment, a pair of tabs each associated with one of the end sections are respectively displaced toward one another and into corresponding respective cavities each associated with the other of the end sections to secure the end sections together.
