<p>The pneumatic equipment is for separating and transporting sheets on a sheet working machine. The equipment includes suction heads attached to the bottom end of spring-loaded pistons which are each guided in a cylinder. The top part of the cylinders above the piston and the bottom part of the cylinders below the piston are connected together and the supply of suction air to the cylinders is controlled by a rotating valve. In part of the rotating have (9) controlling the suction air, there is an additional compressed air connection (19). The piston (15) of the rotating valve (9) includes a longitudinal channel (20) which is stretching from the compressed air connection (19) to the outlets of suction air (10, 13) and is separated from the suction air channels (16, 17, 18).</p> |
