Patent ID: 7946571

Claim:
A method for controlling feed of sheets to a sheet-fed printing press with a sheet feeder unit ( 1 ), said sheet feeder unit comprising multiple components for supplying the sheets ( 8 ) in a stack ( 9 ) for separating the sheets ( 8 ) from the stack ( 9 ) and for conveying the sheets ( 8 ) to a feeder printing mechanism ( 7 ) of the sheet-fed printing press; said method comprising: providing an individual drive ( 19 , 28 , 31 ) assignable to each of said multiple components; said individual drives ( 19 , 28 , 31 ) operating in synchronization with one another during printing by the sheet-fed printing press; inspecting said sheets to detect a defect that requires shutting down said sheet feeder; shutting down said sheet feeder unit in response to detecting said defect, said shutting down comprising eliminating the synchronization between at least two individual drives ( 19 , 28 , 31 ) and shutting down said at least two individual drives individually to assume a predefinable position for each individual drive, wherein said predefinable position is defined such that each of said individual drives ( 19 , 28 , 31 ) is synchronized in relation to each other again upon resuming operation of the sheet feeder unit from said predefinable position.
