Abstract
A filling machine for packaging divided solid material having a conduit for feeding the material under pressure into a packaging container, wherein an elastic liner is disposed in and extends along a part of the length of the conduit, has its opposite ends secured to the conduit, and cooperates with the inner surface of the conduit to form a cavity. The conduit is formed with a vent opening to the cavity to permit outward expansion of the liner when material is flowing through the conduit and inward contraction of the liner when there is no flow through the conduit, thereby flexing the liner to crack and break off material adhering to the inner surface of the liner.
