ABSTRACT:
A method of aligning sheets during stream feeding of a multiplicity of sheets over a feed table to a first steadily rotating cylinder of a sheet-processing medium includes in a first feeding stage, conveying the sheets in an imbricated arrangement thereof via the feed table and in a given direction to an alignment region; in a second feeding stage, aligning a lateral and a leading edge of the sheets in the alignment region while the sheets remain in the imbricated arrangement thereof and without interrupting movement of the sheets in the given direction and, in a third feeding stage, accelerating the speed at which the sheets are stream fed to a peripheral speed of a rotating cylinder and feeding the sheets to the first steadily rotating cylinder, while finally aligning the sheets at front markers.
