ABSTRACT:
An article of manufacture useful in the production of sausages comprising a hollow rod consisting of a longitudinally gathered packing tube and a surrounding support sheath of formable sheet material such as polyethylene with integral end walls each having a central opening therein, said integral end walls being formed in the shape of a truncated pyramid provided with at least two permanently shaped end wall edges radially arranged with respect to the center of the end walls; the end walls are formed by folding the projecting edges of the sheath to form outwardly-projecting, double-layer, triangular flaps; and heat-sealing the sides of the folds to each other; the openings in the end walls of the support sheath allow insertion of a filling tube of a filling machine into the hollow rod in the interior cavity of the support sheath.
