A package squaring device for folding flaps on cartons traveling on a continuous carton conveyor, including a lug attached to an endless flight chain, a flap tucker pivotally connected to the lug, and a cam bar slidably linked to the flap tucker. The lug further includes a member constructed and arranged to engage and stabilize a carton. An endless flight of package squaring devices are synchronized with the continuous carton conveyor so that one or more package squaring devices are traveling operationally adjacent to a carton. The cam bar is forced up and lifts the flap tucker as the package squaring device travels over a cam. The flap tucker is designed to fold a flap on a carton when it is lifted. The cam bar is forced down and lowers the flap tucker when the package squaring device travels off of the cam. The flap tucker of the present invention forms a moveable plow for laterally folding a carton flap while minimizing the longitudinal component forces that tend to skew cartons.
