Abstract: An apparatus (FIGS. 3 to 7) for manufacturing food products such as skinless sausages comprises a tube which contains a plurality of plugs strung along a wire. The plugs are shaped to define sausage end shapes and spaced to define sausage-shaped compartments for filling with sausage-forming material. The plugs and wire are driven through the tube by a motor-driven sprocket which has peripheral recesses for reception of the plugs. Between the recesses the sprocket periphery has slots for receiving the wire. The contents of the tube are cooked by being heated and then cooled by suitable fluid jackets around the tube, or otherwise. In other embodiments, a flexible tube is pinched to form sausage compartments which are moved peristaltically (FIGS. 1 and 2) and a belt having partition-forming formations is rolled within the tube (FIGS. 8 to 11).
