ABSTRACT:
An improved method and apparatus for transferring a load such as a stack of cardboard sheets from an aerator to the receiving end of a cutting press. Sheets of material are stacked on a first pallet having a plurality of spaced support members defining a fork-like configuration having an elongated passage between each pair of spaced supports. The free ends of the spaced supports are adapted for common connection to a transverse rod to provide a generally rigid support surface defined by the spaced supports. The pallet is transported with the stack loaded on its support surface by a forklift to a predetermined location above a movable base pallet which is adapted to align the first pallet in superposed relation thereupon as the first pallet is lowered in place. The base pallet includes a plurality of spaced supports corresponding to the spaced supports of the first pallet. After the two pallets become engaged, the connecting rod of the first pallet is removed. The pallets are then moved to the receiving end of the cutting press. The press is provided with a lifting mechanism which includes a plurality of lifters that can be elevated vertically through the passages defined by adjacent pairs of the spaced supports of the pair of engaged pallets to effect vertical transfer of the stack from the pallets onto the lifters. The lifters are elevated intermediate the aligned supports to a predetermined height so that the stack is raised by the lifters a distance sufficient to permit the engaged pair of pallets to be withdrawn.
