A rigid drive and drill device is used to transmit a drill force to the compacted stack of paper. Stacks of paper are rested on top of a table (3) and vertical drills (2) powered by a drive mechanism (1) concealed in the bottom of the machine are used to drill holes into the stack from the underside of the table whilst a press bridge (4) is being pressed down on top of the stack.
