Image Number 6 for United States Patent #5211599.
Casing material is paid out from the stuffing horn of a food emulsion extrusion system to stuff a food emulsion product. The casing material is drawn over a sizing means which provides varying degrees of sizing and hold back force to the casing material as it is paid out. The degrees of sizing and hold back force are adjustable while the casing is being stuffed with extruded food emulsion. New casing material may be loaded onto the stuffing horn over the sizing means without removal of any element of the sizing means from the stuffing horn.
