Abstract: A method and apparatus of buffering sheets of cut stock in block-shaped stacks ranged in rows between stock-cutting machinery and further processing machinery, whereby each row is also block-shaped. Each row produced by the cutting process is forwarded to a buffer's intake and thence to a marshaling area where it is combined with previously forwarded rows into a group. Each group is forwarded to the buffer's outtake and combined with any other rows already there. The most downstream row of the group is forwarded to the further-processing machinery.
