ABSTRACT:
A printing press having a device for uniformly providing a suction force on a plane body on a support, the device comprising a closed suction chamber having a supporting surface, the supporting surface featuring suction ports. A blower, assigned to the suction chamber, produces an underpressure or vacuum pressure in the suction chamber. The device is designed so as to increase the suction capacity in the marginal area of the body to be sucked by using as little energy as possible, Also, a device for uniformly providing a suction force on a plane body on a support, the device being especially suitable for printing machines and their accessories, the device comprising a closed suction chamber having a supporting surface, the supporting surface featuring suction ports, a blower being assigned to the suction chamber and producing an underpressure in the suction chamber, and the device being designed so as to increase the suction capacity in the marginal area of the body to be sucked by using as little energy as possible.
