Abstract
The device for the control of blowing air is connected to a compressed-air source and it includes at least one outflow orifice. The device has a valve element which is moveable into a first position in which blowing air flows from the compressed-air source at least through a first duct to the outflow orifice and which is moveable into a second position in which blowing air flows from the compressed-air source at least through a second duct to the outflow orifice. A volume flow through the second duct is greater than a volume flow through the first duct. The device is formed as a basic body which is constructed in such a way that a plurality of such basic bodies can be assembled to form a blowing-air body, such as a turner bar in a printing machine.
