Abstract
Abstract In an apparatus for the descrambling and aligning of paramagnetic cans, an elevator conveyor has a magnetic plate directly beneath the upper flight of the belt, the magnetic plate having an upper end contoured so as to be in a plane substantially tangential to the upper roller so that the cans riding on the elevator conveyor are held in an upright position by the magnetic attraction force of the magnetic plate and are conveyed onto a discharge conveyor in the same upright position.
