A shuttle for advancing the free end of a flat sleeve of casing onto a stuffing horn includes a bore therethrough and a vacuum manifold which causes the casing to expand into gripping relationship with the bore, to permit the shuttle and casing end to be advanced onto the horn. When vacuum is released from the manifold, the casing is released from the gripping relation with the shuttle bore and moves towards a gripping relation with the horn, which is increased by reducing the pressure in the horn. This permits the shuttle to be withdrawn at least sufficiently to apply a casing brake to lock the casing to the horn. The shuttle is also used to consolidate meat stuffed into the casing by locking the casing to the shuttle with the vacuum manifold and moving the shuttle away from a restricting orifice surrounding the casing.
