Apparatus for handling magnetizable sheet material, and especially heavy metal plates, which apparatus comprises an overhead conveyor characterized by a supporting frame structure on which a plurality of magnetic roll or roller assemblies are mounted which roller assemblies include a magnet structure with a core having end extensions on which are rotatably carried sheet contacting and supporting rollers with associated pole extension members which are spaced along and extend radially of the axis of the core and which present a downwardly facing bottom surface area of substantial length extending fore and aft of the rollers and in spaced, confronting relation above the top surface of the material contacting the rollers so as to provide a wide flux path which is effective to draw the material into contact with the rollers, the pole extension members having non-magnetic wing portions enabling the connecting of successive roll assemblies being supported for limited vertical movement so as to afford sufficient flexibility to handle, with a high degree of efficiency, plates presenting an uneven or irregular surface for contact with the roller surface.
