Abstract: The invention pertains to a device for the packaging of free-flowing fill materials in a tube-shaped casing with a feeder tube to conduct the flow of fill materials. The feeder tube features a hookup, a mouth, a basically straight first segment adjoining the hookup, with a first longitudinal axis, and a second segment that is conjoined with the first segment and proximate to the mouth. The first segment is designed to accept and conduct a casing on its outer surface. The casing infeed consists of a plastic filmstrip, which is formed into a tube around the first feeder tube segment. The second segment is designed to further conduct the plastic filmstrip-derived, newly formed casing. Alternatively, a supply of casing and/or net material may be loaded onto the second segment from its mouth. Upstream and ahead of the first segment, the feeder tube features a feeder tube swivel bearing (140) around the first longitudinal axis.

Abstract: A food emulsion casing end-closure, and the method of making it, are disclosed. The end-closure is formed of a twist knot through which an air escape aperture is extended. The twist knot forms part of a wadding which is stuffed into the bore of a shirred casing stick and interference fitted therewith. The wadding acts as a shock absorber for the initial shock of extruded food emulsion and serves as means to enhance the consistency of that initial portion of extruded food emulsion. The twist knot is sufficiently tight that it can serve as a permanent end-closure or it may readily be opened by untwisting. Also provided is a lock means for maintaining the twist knot as such.
