ABSTRACT:
An inverter apparatus for strips of sheet material which are affected by a magnetic field. The apparatus includes a pair of parallel drums which rotate in opposite directions immediately adjacent each other. Mounted within the drums in prescribed and fixed relationship are permanent magnets. A strip adheres to the first drum under the effects of the magnets within and rotates with that drum until it comes between the two drums. At that point the strip enters the field of the magnets in the second drum and departs the field of those in the first whereby it adheres to the second drum. The strip rotates with the second drum until it departs the field of the magnets therein, whereupon the strip drops off the drum in inverted relationship.
