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.
Claims2
In an apparatus for feeding blanks from beneath a pile of blanks, each blank having a front edge with an angled cut-out, said apparatus including a tongue and pivoting vacuum device which separates the front edge of the bottom blank from the pile, an extractor roller, and rotating feed segments the engagement edge of which cooperate with the extractor roller to receive the fed blanks, the improvement comprising separator plates mounted on the rotating feed segments which align the blank in the direction of conveyance and feed the same to the extractor roller and the engagement edge of the feed segments, the front edges of the separator plates each having an outward bevel in the outer zone, said bevel having a bevel angle greater than the angle of the angled cut-out of the front edge of the blank being fed.
