<p>A device for driving tools for cutting flat articles comprises a rotary organ (10) borne rotatably internally of a tubular body (7) and exhibiting an axial stem (4) to which a cutting organ (5) is constrained. A motor group (2) axially constrained to the rotary organ (10) is destined to activate the axial stem (4) of the rotary organ (10) in rotation. The body (7) is through-inserted axially slidably internally of a tubular jacket (17) affording internally thereof a cylindrical chamber (11) destined to be sealedly engaged by an annulus (8) fashioned externally of the body (7) and in communication with pneumatic supply means in order to realise a pneumatic actuator organ destined to command axial translation of the body (7).</p> |
