Apparatus for automatically folding the end closure of a carton of rectangular cross section which includes a cover panel hinged to a rear sidewall of the carton and a pair of flanking gusset panels which are each respectively hinged to one edge of the cover panel and to an adjacent sidewall. The carton is continuously moved along a conveyor path with one of the gusset panels leading and the other trailing. A folding head moves along a parallel conveyor path and translates to a location adjacent the carton. An abutment adjacent the conveyor path contacts the leading gusset panel and folds it inward along a line at about a 45 DEG angle to its hinged edges. An arm mounted on the folding head is caused to swing relative to the conveyor to fold the trailing gusset panel inward along a line at about a 45 DEG angle to its hinged edges. |
