The BestPack ARX Indexer is the perfect unit to place in front of the BestPack AS or AQ type Fully Automatic Unifrom Carton Sealers. The ARX Indexer separates and times the cartons in the sealer to insure proper top flap folding and sealing of the cartons with no carton jamming. The indexer also has a timer that is adjustable to control the spacing between the cartons by controlling how long a duration the drop and stop is. This timing ability is useful in timing the speed of cartons being fed down line to such equipment as label printers and or carton palletizers. This unit is the strongest and most positive indexing system in the market.
