A method for making a paper blank from a corresponding paper sheet includes: loading a paper sheet along a longitudinal orientation, resting on a supporting surface that defines a worktop; moving a carriage in parallel with the worktop; making a primary cut on the paper sheet along a cutting orientation perpendicular to the worktop, using a primary blade which slides relative to a primary anvil; making a secondary cut, sliding a secondary blade and a secondary anvil relative to each other at a secondary cutting unit. The primary cutting unit and the secondary cutting unit are actuated by an actuating assembly.
