Abstract

A method of feeding sheets to a printing-technology machine includes individually separating sheets from a sheet pile, conveying the sheets against movable lays for effecting an alignment thereof, and cyclically conveying the sheets from the lays to the machine. A control device coordinates movement of the lays with the individual separation of the sheets from the sheet pile and onward conveyance of the sheets to the machine. Data related to characteristics of the sheets are processed in the control device for generating actuating signals for a separate, controllable drive system. The lays are moved by the drive system. A device for performing the method is also provided.
