ABSTRACT:
A method and apparatus for unloading blanks of paper, cardboard, plastic, etc. that are stacked as blocks on a pallet and that are subsequently supplied as blocks of blanks for further processing or temporary storage. The individual blocks of blanks are successively lifted from their support via an insertion tool, with a pressure foot preventing an undesired shifting and a holding foot securing the position of the respective block of blanks on the insertion tool. The method and apparatus include provision of a slightly pivotable insertion tool as well as structural elements for moving those stacks or blocks of blanks, relative to their support, that are disposed on the pallet at the edge thereof.
