Abstract
A method of and apparatus for stacking articles which is used in the embodiment herein to stack plastic carriers for holding a plurality of filled containers, wherein each carrier has a top panel and a skirt extending downwardly therefrom. Articles are successively moved into a prestacking position and then elevated into a lifting rack. The rack is reciprocated up a guideway, for receiving a plurality of the articles and maintaining them in a stacked relationship, to a stack support means and then back down to receive more articles from the pre-stacking position. The guideway is preferably provided with an open side for removal of a stack of articles, and is tilted away from the open side to retain the articles therein by gravity. To enable smoother transfer of articles from the pre-stacking position to the lifting rack, the articles are inclined at the pre-stacking position to an angle which is perpendicular to the inclined guideway and elevated into the rack.
