摘要：A die assembly 1 comprises a die body 2 having a bore 3 and a coaxial gas supply pipe 4, the free end 5 of which projects outwardly from the die face 6, an annular die outlet 7 being defined at the die face 6 between the bore and a spacer 8 mounted coaxially of the gas pipe 4. An expandable cereal product, containing air, is supplied to the left hand end of the bore 3, and air is supplied to the pipe 4 through pressure regulator (not shown). On exiting from the die outlet 7 air bubbles in the cereal product expand rapidly so as to thicken the wall of the cereal tube 9 while the pressure differential between the inside and outside of the cereal tube 9 results in inflation of the tube 9, thereby reducing the wall thickness of the cereal tube. Bubbles in the tube 9 are elongated in the circumferential direction of the tube, due to inflation of the tube between regions 10 and 11. A further supply pipe may be provided for feeding an edible filling material within the expanded tube. This further pipe may be annular, surrounding the gas supply pipe 4, or fitted within that gas supply pipe. The expanded product may be crimped by means 15 (Fig 5, not shown).
