Abstract
A top panel pre-folder for a form, fill and seal packaging machine for forming, filling and sealing an extended top panel gable top carton includes an mandrel positioned along the machine processing path that is movable from above the carton to the interior of the carton as the carton moves along the processing path. A pair of spaced apart pivotal arms, each disposed on opposing sides of the mandrel and transverse to the processing path, is pivotal about an axis toward and away from the mandrel. Each arm includes a flap mounted thereto having a raised portion extending from a face of the flap. The arms pivot to contact the flaps with gable side panels of the carton to infold the gable side panels inwardly over the mandrels. The flap raised portions contact the gable side panels at about gable side panel/vertical side panel junctures.
