ABSTRACT:
A filling station for filling pleat-sided bags transports such bags in flat form to a filling position. A plurality of spreading members are disposed adjacent the front and rear faces of the bag, and have claws thereon which engage the opposing interior edges of the bag adjacent its openable mouth. The spreading members adjacent each given side of the bag are moved away from one another in a direction substantially parallel to the planes of the front and rear bag faces, and the spreading members on opposite sides of the bag are moved away from one another in directions transverse to said planes thereby to unfold the pleated side faces of the bag and open the mouth of the bag. A filling funnel disposed outside of the bag is moved into the opened mouth of the bag, and bars disposed adjacent the exterior of the several faces of the bag are moved into engagement with those faces to clamp the faces of the bag to the filling funnel during the filling of the bag.
