Delivery and ejection device (20) for flat elements (2) into a machine working them, in particular into a machine (10) of packaging production continuously delivering a plurality of lines of flat elements (2) arranged into parallel streams (22) successively onto three conveyor belts (13, 23, 33). These streams are recurringly delivered into a stacker (40) thanks to a mechanism (60) of drive and interruption of the streams. The device (20) allows to separately reject at least one stream towards a reject conveyor belt (90) comprising flat elements (2) scanned as being defective. The mechanism (60) includes two carriages, one upper (61) and the other lower (62), able to move simultaneously, at the same speed and into opposite direction along a axis parallel to the streams lines (22).
