Abstract
A device for holding components made of a ferromagnetic material that are arranged consecutively in a row and are held in place with one contact surface resting against at least two adjacent magnetic poles of opposite polarity, with the magnetic lines of force between the magnetic poles being concentrated in a region close to the contact surface of the components without magnetically influencing the working surfaces opposite the contact surfaces, in which the component holding capacity of the device is considerably increased, without impairing the residual magnetic field in the edge areas, by arranging multiple rows of the components parallel to each other and assigning to the outer rows of the components additional magnetic circuits that divert or compensate for the residual magnetic field of the working surfaces of the components.
