Patent ID: 8241096

Claim:
A chuck for a meat encasing machine which increases the holdback force on plastic casing comprising: (a) an elongated body having an axial cylindrical bore to accommodate the passage through said body of a casing being stuffed which is placed over a stuffing horn, said bore defining a longitudinal axis about which said body is rotatable and having: (i) an inlet end and an outlet end; (ii) a casing engaging inlet section which tapers inwardly from a large diameter at said inlet to a smaller diameter at a location intermediate said inlet end and said outlet end; (iii) a casing deforming section extending from said intermediate location to said outlet end; (b) a multiplicity of longitudinally extending casing engaging flutes in said bore; (c) the improvement comprising a means for reducing the inside diameter of said bore from about said intermediate location and continuing for a total distance towards the outlet end, of from about one-quarter to about one-third the length of the chuck, thereby providing a holdback force increasing zone.
