  • Apparatus and method for inserting pouches into boxes
    Patent number: 4729209
    Abstract: An apparatus and method for inserting pouches into boxes or lining boxes with pouches is disclosed. Rather than manually line boxes, the apparatus takes a pouch from a horizontal stack of pouches, opens the pouch over an open box, partially inflates the pouch, and, inserts the pouch into the box. A vertically reciprocating mandrel is included with tucker fingers to fold the bag's mouth over the outside perimeter of the box thus presenting a line box ready to receive a product.
