Abstract
A packaging machine useful for packaging fluidized dry, divided, solid material into containers such as valve bags is provided with an isolator section for isolating forces generated in the flow path of the material from a filling and weighing section. The flow path includes a filling spout that extends into the container through a valve formed therein and is sealed in the valve by an inflatable sleeve on the filling spout, the sleeve being so constructed that only that portion that enters the valve is permitted to expand.
