Patent ID: 7997202

Claim:
A method of operating a web offset printing press that prints and processes at least one web of materials, comprising the steps of: providing printing units and/or printing unit assemblies, with at least one folder, and with transport elements; transporting the at least one web of materials by the transport elements through the printing press into the at least one folder; electrically driving the at least one folder, the printing units and/or printing unit assemblies and the transport elements at least partially mechanically independently of each other; synchronizing during printing operation, specified setpoint value assignments, at least one master axis ( 13 ) with an electronically generated synchronization clock of at least one drive-related control; generating, prior to synchronization with the at least one folder and the transport elements in an initial state, a specific master axis based on the position and/or condition of motion of the at least one folder, which said specific master axis deviates from a course of setpoint value assignments of the at least one master axis; synchronizing, from an initial state, the transport elements and the at least one folder by synchronizing specified setpoint value assignments to the specific master axis, by performing compensation motions of the transport elements and the at least one folder during the compensation motion interval, such that the transport elements during the synchronization perform a motion that is synchronous with a motion of the folder in terms of a parameter selected from the group consisting of angle, speed, and both during the synchronization; and synchronizing the setpoint value assignments of the specific virtual master axis with setpoint value assignments of the master axis.
