Bag Spout Interfaces
                                      The operator interface with the
                                      discharge spout varies depending
                                      on the bag style and material
                                      characteristics.  The design objective
                                      for every application is a user
                                      friendly access to untie or re-tie the
                                      spout while providing dust free and
                                      complete material discharge.



          E3 Bag Spout Interface:  The E3 [Engage, Elongate, Evacuate] provides
          a dust tight seal with the discharge spout of the bag while eliminating the
          potential for contaminates to enter the process.  Material flow from the bag is
          greatly enhanced  for semi to non-free flowing material when the E3 is located
          in the sealed, lowered position.  The double wall design prevents material
          spillage when untying, retying, or removing an empty bag.

                              lowers the entire E3 assembly
