Abstract
Abstract An improved stuffing horn for a meat encasing apparatus which includes as an integral part thereof a rotating stuffing tube. The stuffing tube has a horn mounted on its forward end in order to assist in the casing filling process. The stuffing horn, or fin head, of this invention is preferably multiple threadably engaged with the stuffing tube and is designed to provide a smooth bore through the stuffing tube and into the fin head. The fin head is securely fastened to the stuffing tube but yet easily removable and since a smooth bore exists meat emulsion flow through the tube is generally laminar without impeding turbulence and drag.
