There is disclosed an apparatus and a method of making encased products, particularly sausages. In a preferred embodiment the apparatus (10) comprises a hollow member (12) connected to a supply of a flowable medium such as a meat emulsion, a restriction element (14) with one end located adjacent a discharge outlet (16) of the hollow member (12) and the other free end (36) defining a face (38) substantially transverse to a direction of flowable medium flow, and a tubular element (18) disposed around the restriction element (14) to define a substantially annular flow passage (42) therebetween. The flowable medium is extruded through the hollow member (12), through the annular flow passage (42) and over the free end (36) of the restriction element (14), when it is urged radially inwardly, to underfill a casing (40) which is shirred around the outer surface of the tubular element (18). Other embodiments of the invention are discussed.
