ABSTRACT:
A feeding device for a sheet processing machine for stream feeding to the sheet processing machine, in mutually overlapping relationship, equally thick sheets taken singly from a pile of the sheets, in combination with an alignment device for laterally aligning the sheets as they are being fed to the sheet processing machine, the feeding device includes a feed table having, together with the lateral alignment device, surfaces whereon the stream-fed sheets are supported, at least one section of the surfaces of the feed table and the lateral alignment device being disposed at a different level from that of another section thereof, at least while the sheets are being aligned, the difference in the levels being such that a preceding sheet being aligned, at the moment lies fully on a surface section of the lateral alignment device, the latter surface section being at substantially the same level as the upper surface of a leading portion of a next succeeding sheet underlying a trailing portion of the preceding sheet.
