A device for manufacturing a frusto-conical shaped meat product by means of a mold casing that receives ground meat under pressure. The mold casing has an inner wall, a first lateral end, and a second lateral end. The mold casing has a frusto-conical shape, for forming the meat product into a desired shape and cross section. An end fitting is secured to the discharge end of a meat stuffer. The end fitting includes a plurality of pivotable, flexible, adjacent, partially overlapping fins. The fins pivot as they are moved relative to the mold casing, and in that way maintain contact with the inner wall of the mold casing.
