It is provided with a longitudinal bearing (2) mounted on a frame (1) and framed by two side, vertical and parallel guides (9) and (10), the position of the latter being adjustable in order for the spacing thereof to match the thickness of the spring carcass, which is hauled by a thruster (4) driven by a motor reducer (5) intermittently towards the working area of two stapling heads (12-12) where a retractable ram (15) receives the spring action directly and adjusts, in accordance with the latter's diameter, the position of the balance lever acting on the proximity detector that in turn controls the movement of the motor reducer (5) in order for each spring to duly face the stapling heads (12). Beyond these stapling heads is provided a tray (21) that can swing by means of a lower pneumatic cylinder capable of overturning the spring carcass (3) once all the springs on one of its sides have been stapled, in order that the latter may continue to receive the machine action on another edge, until its whole perimeter is finished.
