ABSTRACT:
A laminated article in particular for electrical use including mutually superposed metal laminations provided with elements or clips for connecting the laminations together. The clips project from a surface of the laminations and are formed by deforming the laminations. The laminations include cavities angularly spaced apart from the clips. Each cavity is arranged to receive a respective clip from an adjacent lamination such that the laminations are coupled together via the clips and cavities. The cavities and clips constitute separate coupling elements of male-female type. The cavities are preferably through cavities extending from one planar surface of the lamination to an opposed planar surface.
