Abstract

1. A process for assembling by glueing a magnetic circuit resulting from the stacking of metal plates and comprising, suitably individualised, at least two cores (11A, 11B) which are parallel to each other, and at least one yoke (12) for connecting said cores at one at least of their ends, the process being of the kind wherein glue (17) is disposed between the surfaces which are to be brought together of said yoke (12) and said cores (11A, 11B), and a clamping pressure which is suited to the desired glueing effect is applied thereto in a direction which is perpendicular to said surfaces and therefore parallel to the plane of the metal plates (15, 16) in question, the metal plates (15, 16) making up the cores (11A, 11B) and the yoke (12) being left free of any means for fixing them together before the glueing operation to be carried out, characterised in that, in said glueing operation, prior to the clamping pressure (F) and in a direction perpendicular to the plane of said metal plates (15, 16), a moderate holding pressure (P) is applied thereto, to prevent them from riding over each other in the clamping operation while permitting relative displacement thereof parallel to themselves, in such a way as to prevent, as a corollary, glue from penetrating between the metal plates.
