ABSTRACT:
To prevent an end of a filled container, upon heating by a hot air for subsequent welding of edges thereof, from coming into contact and sticking to a retainer, a centering gas such as, for example, air is supplied from an external source to the container end. Edges of the filling opening of the container are heated by a hot gas for a subsequent closing of the same through a nozzle introducible into the filling opening of the container end. A centering fluid is directed at the end of the container with a component of flow of the centering in an axial direction of the container to provide for a contact-free centering of the container end.
