<p>In packing machines which produce aseptic packing containers for e.g. foodstuffs, it is of greatest importance that the machines can be cleaned and sterilized in a satisfactory manner prior to the production of packing containers. In accordance with the invention a method and an arrangement are provided on a packing machine for the sterilization of the lower end of a filling pipe l0 as well as of surrounding parts of a packing material tube 8. Use is made for this purpose of a connecting element 20 which connects two feed ducts ll,l2 present in the filling pipe l0 to each other so that cleaning and sterilizing agent can circulate in the filling pipe. In a subsequent stage the connecting element 20 is removed so that sterilizing agent can be made to circulate also along the outside of the filling pipe l0 and in the packing material tube surrounding the filling pipe, whereupon the production of the packing containers commences. </p> |
