Abstract
According to the invention, separator plates bevelled at the front edges provided on the rotating feed segments of a sheet feeder, more particularly for envelope machines, which finally separate from the pile of blanks a blank for feeding, the front edge of the bottom flap of the blank having been separated from the pile by means of a tongue and vacuum device. The separator plates align the blank in the direction of conveyance, smooth it out, and then feed it to the extractor roller and engagement edge of the rotating feed segments.
