<p>F-shaped lamination parts (2a,b) for forming electromagnetic cores are cut from a strip of material, the lines of cut being such that pairs of Fs have their parallel cross members (4a,b,6a,b) interfitted with each other and each pair of Fs is nested with the adjacent pair of Fs. The Fs are arranged in two or more rows with the stems (8a,b) of the Fs in each row at an angle to the longitudinal edge of the strip so that substantially the only material wasted is a saw-tooth shaped portion along each edge. The Fs have resiliently interengageable projections (18a,b) and recesses (22a,b) for holding the parts together in an electromagnetic core.</p> |
