ABSTRACT:
A cuffing assembly for flexible bags inserted into a receiving open carton includes cuffing fingers at each carton corner. The fingers are movable between a retracted position for insertion into a bag and an extended position in which they can overlap the carton corners. Air is discharged through air outlets adjacent the outer ends of the cuffing fingers to minimize frictional forces between the bag and cuffing fingers to prevent tearing of the bag as the cuff is being formed and during subsequent retraction of the cuffing fingers.
