A method of stuffing flexible tubular casing with foodstuff, which comprises: (a) providing for a stuffing machine a supply of shirred casing articles, each comprising an elongate, substantially rigid and uniformly cylindrical tube forming throughout its length a straight cylindrical passageway for conducting foodstuff through the tube and having fixed coaxially onto said tube a shirred and longitudinally compacted length of a flexible tubular casing, the pleats of which grip onto said tube so as to resist displacement relative thereto, said casing length having a fore end portion thereof extended forward from said pleats to and over the fore end of said tube into a forward casing portion for receiving foodstuff; (b) transporting a said shirred casing article from said supply to a position of axial alignment of the aft end of said tube of the article with a foodstuff delivery outlet of the stuffing machine; (c) then connecting said outlet in communication with said aft end; (d) then pressing foodstuff from said outlet into said aft end and through said tube of the article to fill said forward casing portion, press it forward, and progressively draw forward and fill the casing of the article at the fore end of the said tube; (e) during said pressing of foodstuff, driving said article about its longitudinal axis and thereby rotating about said axis the said tube, the foodstuff therein, the pleats thereon and a said casing fore end portion during filling of said casing length of the article; (f) upon completion of said filling, disconnecting said outlet from said tube aft end and displacing the said tube depleted of casing away from said position; (g) and also upon the completion of said filling, stripping foodstuff from said tube depleted of casing and discharging said tube depleted of casing away from the stuffing machine; and (h) repeating one after another with others of said shirred casing articles said transporting, connecting, pressing, driving, disconnecting, displacing, stripping and discharging steps. 6. A method according to claim 1, said stripping being effected after said displacing of the said tube depleted of casing away from said position. 7. A method according to claim 1, said connecting being effected by displacing axially, onto said aft end of the said tube, the delivery end of a conduit constituting said foodstuff delivery outlet. 8. A method according to claim 7, said driving of said article being effected by rotating about an aft end portion of said tube, after said aft end is connected with said outlet, at least one driving element engaged with a drivable part fixed on said tube at a location between said aft end and said pleats. 9. A method according to claim 1, said shirred casing articles being arranged parallel to one another in said supply, and said transporting of a said article being effected by moving the article in a path transverse to its length from said supply to said position of axial alignment with said outlet. 10. A method according to claim 1, further comprising, when said aft end of said tube of a said shirred casing article is connected with said outlet, positioning the fore end of the said tube and at least part of a said forward casing portion in an inlet of a rotary chuck device carrying elements for pressing inward and rotating a filled portion of said casing, and during said driving of the article, driving said chuck device at the same rotational speed so that the filled casing while being pressed forward from said tube of the article and through the chuck device is engaged by said chuck device and rotated by it at the speed of rotation of the said tube, the foodstuff therein, the pleats thereon and a said casing fore end portion. 11. A method of stuffing flexible tubular casing with foodstuff, which comprises: (a) providing for a stuffing machine a supply of shirred casing articles, each comprising an elongate, substantially rigid and uniformly cylindrical tube forming throughout its length a straight cylindrical passageway for conducting foodstuff through the tube and having fixed coaxially onto said tube a shirred and longitudinally compacted length of a flexible tubular casing the pleats of which grip onto said tube so as to resist displacement relative thereto, said casing length having a fore end portion thereof extended forward from said pleats to and over the fore end of said tube into a forward casing portion for receiving foodstuff; (b) transporting a said shirred casing article from said supply to a position of axial alignment of the aft end of said tube of the article with a foodstuff delivery outlet of the stuffing machine; (c) holding the casing article at said position of axial alignment and moving said outlet towards said aft end for connecting said outlet in communication with said aft end; (d) then pressing foodstuff from said outlet into said aft end and through said tube of the article to fill said forward casing portion, press it forward, and progressively draw forward and fill the casing of the article at the fore end of the said tube; (e) during said pressing of foodstuff, driving said article about its longitudinal axis and thereby rotating about said axis the said tube, the foodstuff therein, the pleats thereon and a said casing fore end portion during filling of said casing length of the article; (f) disconnecting said outlet from said tube aft end upon completion of said filling and displacing the said tube depleted of casing away from said position; and (g) repeating one after another with others of said shirred casing articles said transporting, connecting, pressing, driving, disconnecting, and displacing steps. 12.
