Abstract

An assembly for controlling individual positioning elements in a delivery region of a sheet-fed printing machine, including at least one computer, at least one input device connected to the computer for inputting therein characteristic data specific to a sheet and/or to the printing machine, the computer having devices for further processing the characteristic data, and a control device operatively connected to the computer and having individual positioning elements for causing a format-dependent adjustment in accordance with the inputted characteristic data, the computer having devices for calculating, from the characteristic data, energy of the sheet oncoming to the delivery region and, in accordance with the calculated energy value, also for calculating an actuating value for at least one individual positioning element in the delivery region so that energy withdrawal by the individual positioning element is substantially equal to the energy of the oncoming sheet in the delivery region, the control device having devices for actuating the individual positioning element in accordance with the calculated value; and method of operation.
