  • Patent number: 4242024
    Abstract: A fork lift mechanism is associated with apparatus for palletizing long sheets of strip material at the discharge end of a shearing press. The long sheets are palletized on an underlying conveyor having a width corresponding to the length of the sheets in the direction of discharge from the press. The fork lift mechanism is supported above the conveyor for displacement toward and away from the shearing press in the direction of the discharge and is adapted to be elevated and lowered relative to the conveyor. The fork lift mechanism is operable to receive and support a plurality of short sheets from the press to form a stack on the fork lift mechanism and to position a plurality of such stacks on a pallet on the conveyor and in side-by-side relationship on the pallet in the direction of press discharge and/or in the direction of conveyor movement.
