The Vari-Right, a three-flap, right-angle closer for top-load cartons has a revolutionary variable pitch design. It incorporates the dual benefits of lugged carton control and random in-feed timing - both the result of "infinitely variable" flight centers. Patented "pop-up" lug technology has been optimized in a full servo motor platform. Vari-Right's unique design couples the carton control benefits of a lugged carton closer without sacrificing the advantages of a random style carton infeed.
