Abstract
The invention relates to a sheet feeder for the individual feeding of sheets to a sheet treating machine. A first sheet pile is carried by a main pile table, and sheets from this sheet pile can be fed by a sheet separating device, optionally via a first feed table, to the sheet treating machine. A further sheet pile is carried by an auxiliary pile table. Sheets can be fed by a second sheet separating device from this further sheet pile to the sheet treating machine, again optionally via a second feed table. Using this arrangement, in place of the sheets from the first pile table, sheets from the auxiliary pile table can be fed to the sheet treating machine without interruption, as the sheet feed from the two piles is carried out in the same rhythm. Preferably a control circuit is used to meter out a selected number of prerun sheets from the auxiliary pile table followed without interruption by another selected number of continuous running sheets.
