ABSTRACT:
Apparatus for automatically outfolding the leading and trailing gusset panels of the end closure of a rectangular carton being moved along a predetermined path on a continuous conveyor. First and second arms are attached to a vertical shaft and to a sleeve mounted for independent rotation about the shaft. The shaft and sleeve rotate in opposite directions so that one arm contacts the leading gusset panel and folds it outward along a line at an angle to its hinged edges and the other arm subsequently contacts the trailing gusset panel and similarly folds it outward. A plow positioned adjacent the conveyor path begins to plow the major end closure panel toward the carton opening while the rotating arm is in contact with the leading gusset panel.
