Claims
- 1. A composite casing article comprising:
- (a) a shirred length of casing having an axial bore of sufficient diameter to receive a stuffing horn therethrough, said shirred length having a fore end and an aft end and an unshirred portion of casing extended forward from said fore end;
- (b) a diametrically expandable tubular leader in said bore, said leader having fore and aft end portions extending axially outward from said bore; and
- (c) said leader aft end portion constituting means for attaching to said leader the leading end of a continuous web which is formable to a casing tube about the stuffing horn and which is drawable through said bore by said leader.
- 2. A composite casing article as in claim 1 wherein said tubular leader is a web having longitudinally extending overlapped side margins.
- 3. A composite casing article as in claim 2 wherein said side margins are unsealed thereby rendering said tubular leader diametrically expandable by the circumferential slippage of said overlapped side margins, one with respect to another.
- 4. A composite casing article as in claim 2 wherein said web comprises a metal foil or a metal foil-plastic web laminate.
- 5. A casing article as in claim 1 including adhesive means on said leader aft end portion.
- 6. A casing article as in claim 1 wherein said unshirred casing portion and said leader fore end portion are merged and joined together to form a closed end of a multilayered composite casing.
- 7. A composite casing article as in claim 1 including:
- (a) a sleeve having a fore end, an aft end and an axial bore of a size sufficient to fit over a stuffing horn;
- (b) said shirred length of casing being disposed on said sleeve; and
- (c) said tubular leader extending longitudinally through the bore of said sleeve.
- 8. A composite casing article as in claim 7 including a forming means at said sleeve aft end, said forming means being operable to form a casing tube out of a web which enters said forming means and passes through said forming means and into said sleeve.
- 9. A composite casing article as in claim 8 wherein said tubular leader has its aft end portion extending through and rearward from said forming means.
- 10. A composite casing article as in claim 7 including a sizing means on said sleeve fore end for expanding casing drawn from said shirred length and over said sizing means.
- 11. A composite casing article as in claim 1 including:
- (a) a first sleeve disposed within and extending substantially the full length of said tubular leader, said sleeve having a fore end;
- (b) a casing sizing means on said fore end;
- (c) a second sleeve disposed coaxially about said first sleeve and tubular leader said second sleeve having an aft end spaced from said first sleeve fore end;
- (d) a forming means on said second sleeve aft end operable to form a casing tube about said first sleeve from a web passing into and then forward through said forming means towards said first sleeve fore end, and said leader aft end portion extending rearward through said forming means; and;
- (e) said shirred length of casing being disposed on said second sleeve.
- 12. A composite casing article as in claim 11 wherein said shirred casing length has an unshirred portion extended forward over said sizing means and said tubular leader has a portion also extended forward over said sizing means and merged with said unshirred portion.
- 13. A composite casing article as in claim 12 including means joining together and closing the portions of said unshirred casing and tubular leader forward of said sizing means.
- 14. A composite casing article comprising
- (a) a shirred length of cellulosic casing having an internal bore and an unshirred casing portion extended forward from said shirred length;
- (b) a casing tube disposed in said bore, said casing tube having a fore end merged with said unshirred casing and an aft end portion extending outward from said internal bore;
- (c) said casing tube formed of a web having overlapped side edges which define a longitudinally extending seam;
- (d) a web supply from which said casing tube emanates; and
- (e) said casing tube aft end portion constituting a transition zone in which web drawn from said web supply is formed to said casing tube.
- 15. A composite casing article as in claim 14 including closure means closing said unshirred casing portion together with said casing tube fore end.
- 16. A composite casing article as in claim 14 wherein the length of the web in said web supply exceeds the length of said cellulosic casing in said shirred casing.
- 17. A composite casing article as in claim 14 wherein said longitudinally extending seam is unsealed.
- 18. A composite casing article as in claim 14 including a casing tube forming means in said transition zone.
- 19. A food product comprising a foodstuff encased in a multilayered composite casing comprising:
- (a) an outer layer composed of a tubular wall of deshirred cellulosic casing;
- (b) an inner layer composed of a non-shirred web material having side margins overlapped to define a longitudinally extending seam;
- (c) said inner layer being pressed diametrically outward against said outer layer; and
- (d) said inner and outer layers being closed and joined together at the ends of said stuffed product.
- 20. A food product as in claim 19 wherein said longitudinally extending seam is unsealed.
