ABSTRACT:
A delivery apparatus for a sheet-fed printing press includes a detector, a control unit and a solenoid. The detector detects a moving amount of suction wheels moved by adjustment and generates a signal corresponding to the moving amount. The control unit is connected to the detector and a timing unit of the printing press and generates a signal representing a predetermined length corresponding to the sheet size. The solenoid is located between a powder container and an air source and opens an air path for only a time interval corresponding to the signal supplied from the control unit.
