An accumulator head for an extrusion-blow molding machine. The accumulator head includes an annular inner sleeve member slidably positioned within an accumulator outer barrel, and a tubular inner body member received within the sleeve member. The sleeve member and body member are adapted to be slidable together within the accumulator barrel to expel collected plasticated material. The inner sleeve member includes a pair of external slots formed in the outer surface that communicate with the accumulator inlet and with respective radially extending flow passageways through the inner sleeve to convey plasticated material from the accumulator inlet into a pair of helical flow channels formed in the accumulator inner body member. The flow channels communicate with an outlet area to convey the plasticated material to an inner accumulation chamber through an annular collector channel and an annular flow passageway that provides an extruded parison having a uniform conformation without flow or separation lines. Suitable actuators are provided for together moving the inner sleeve and the inner body member to expel plasticated material, and also to selectively move an inner mandrel to provide a desired parison die outlet opening.
