Abstract
An improved mandrel for use in a shirring machine, having two axially oriented substantially concentric fluid passageways formed therein equipped with two pairs of self-closing valves whereby two fluids may be separately introduced into the passageways for injection into the interior of casing material being shirred thereon. The valve pairs are adapted to be used alternately, whereby a strand of shirred casing may be passed along the entire length of the mandrel without interrupting the fluid flows.
