A conveyor device of the moving belt type comprises two belts arranged with a flight of each parallel to and adjacent a flight of the other, at least one of the belts being a driving belt, one belt being of non-magnetic material and the other belt being of such a construction that it is attracted toward the source of a magnetic field, magnet pole pieces spaced longitudinally of and transversely apart along opposite edge portions of the adjacent flights of the belts and on the side of the flight of the non-magnetic belt remote from the other belt, and a slipper bar disposed longitudinally of the belts between the transversely spaced magnet poles adjacent the belt of non-magnetic material, the belt of non-magnetic material being slidably engageable with the slipper bar. The portion of the non-magnetic belt engaged with the slipper bar lies between the transversely spaced pole pieces, the width of the non-magnetic belt being less than the transverse distance between the pole pieces.
