<p>An improved magnetic conveyor belt in which the belt support is a U-shaped iron rail having a plurality of permanent magnets disposed in the middle of its web between the two legs of the U with the spaces remaining between the magnets themselves and between the magnets and the legs of the rail filled to the level of the permanent magnets with a material which is magnetically non-conductive, thus completely filling in a portion of the U-shaped rail to a predetermined level upon which surface the conveyor rides either directly or through a metal sheet interposed between the top of the magnets and insulating material and the belt whereby the legs of the iron rail will be polarized in one direction and the center portion above the other pole of the magnets polarized in the other direction resulting in a magnetic field extending over a large volumetric space thereby permitting bulkier objects to be reliably carried on the conveyor belt.</p> |
