Title: Stacking apparatus for ferrous sheets

Abstract: Stacking apparatus for ferrous sheets, for example transformer sheets having holes therethrough, comprises a plurality of power-driven magnetic conveyors in lengthwise alignment with each other, for receiving and conveying ferrous sheets on the undersides of the conveyors. Upon deenergization of the conveyors, the sheets fall on a lowerator which is progressively lowered as the stack is formed. If the sheets are pierced, then pins extending vertically above and below the lowerator to a position immediately below the conveyors, engage in the holes in the sheets to align the sheets and retain the stack. The pins do not lower; instead, when the stack is complete, the lowerator and the pins can be removed together transversely of the conveying direction.
