Abstract:
1. A device for processing a surface of objects comprising: a predetermined number of processing stations wherein at least one of said processing stations are configured as contact-free printing stations each having an inkjet printing head; a conveying unit that performs processing movements wherein objects are transported to said predetermined processing stations, said conveying unit having a central controller that both controls, through a feedback control loop, the processing movements of said conveying unit and controls, through a feedback control loop, the processes of said processing stations, wherein said central controller synchronizes said processing movements and said processes of said processing stations which are synchronized by presetting a clock pulse that is correlated with said processes and directly controls said processes via said central controller associated with each processing station of said predetermined number thereof; and wherein said central controller presets a lead frequency that defines said clock pulse, said lead frequency associated with an operating frequency of inkjet droplets issuing from said inkjet printing head that is provided to a computing unit for synchronizing rotation of said objects with said processing stations, said synchronizing rotation being imparted by a drive means of said conveying unit.
