<p>An apparatus for producing and filling tubular bag packages includes a shaping mandrel, about which a sheet of packaging material is shaped into a tube and an open end of the tube is filled with one portion of a product at a time and separated from the formed tube. For sending the portions of the product gently and quickly through the hollow shaping mandrel, a feed apparatus is disposed in the mandrel. The feed apparatus has a plurality of spaced flaps pivotably connected at equal intervals to two synchronous belt drives. In a feed conduit of the shaping mandrel, these flaps define downwardly moved chambers which receive portions of the product and transport them to the lower end of the shaping mandrel, and then, through a relatively narrow return conduit in the shaping mandrel, the flaps return upward again in an upright position by the belts.</p> |
