Abstract: A method and apparatus for producing a plurality of bi-oriented, heat-shrinkable thermoplastic tubular films is disclosed. Thermoplastic resin is extruded through a plurality of annular dies to form a plurality of molten plastic tubes. The tubes are cooled and solidified and sent through a plurality of pinch rollers to stretch the tubes simultaneously in a machine and transverse direction, creating a plurality of tubular films. The films are cooled and heated, and then relaxed simultaneously in a machine and transverse direction. Winding rollers then wind up the finished tubular films.

Abstract: A stuffing method and apparatus is disclosed which produces a stuffed log having a front end portion which is larger in diameter than the remainder of the log. This is accomplished by spacing the sizing disc and pressure ring apart when food product is first introduced into the casing and the immediately pressing the sizing disc and pressure ring together while stuffing the front end portion of the casing and then moving the sizing disc and pressure ring to a set predetermined distance apart and holding them in this position while stuffing the remainder of the product.

Abstract: A hornless stuffing apparatus and method wherein stuffing of casing from a shirred stick is accomplished by utilizing the shirred stick per se as a conduit for foodstuff.
