Abstract
A device for arranging ferromagnetic components a preset distance from one another including an electromagnet defining a pole gap wherein a nonuniform attractive magnetic field is formed with a gradient directed along its axis of symmetry. At least one of the pole pieces of the electromagnet is provided with a ferromagnetic rack adapted to move in the plane in which it lies. The plane of the rack is substantially normal to the direction of the magnetic field gradient. The rack includes teeth which are spaced apart in accordance with a desired preset distances between ferromagnetic componets. The device also comprises a means for feeding ferromagnetic components into the magnetic field, in the direction of its gradient.
