Abstract

Apparatus for the unstacking and transportation of blanks into a subsequently arranged operating chamber of a processing machine, wherein the blanks are transferred from a stack of blanks, by hoisting devices, especially suction bridges, includes a suspended conveyor which conveys the blanks by way of a double-blank control device to a centering station. From the centering station, the blanks, centered in their position, are transferrable into the operating chamber, optionally by way of an intermediate station. At least two stacks of blanks are disposed in series in the conveying direction of the blanks on at least two elevator carts movable at right angles to the conveying direction. Each elevator cart is associated with a separately operable suspended conveyor with associated hoisting units. A further, continuously driven suspended conveyor is provided downstream of the double blank control device which conveyor spans a double-blank depositing unit and terminates over the zone of the centering station.
