摘要： An extrusion molding apparatus includes a die head with first, second, third and fourth annular nozzles. An adhesive extruder is connected to the first and third nozzles, a barrier extruder is connected to the second nozzle and a reclaimed material extruder is connected to the fourth nozzle. Inner and outer main material flow passages are connected to a main material extruder, as well. The annular nozzles and the main material flow passages are connected to an extrusion nozzle for forming a parison. The barrier material extruder has a cylinder which is connected to the second nozzle. A screw lies within the cylinder. The second nozzle has a ridge opposite an end of the screw, for dividing the extruded barrier flow material, mitigating stagnation of the barrier material as it passes through the second nozzle. A method of forming a parison is described, as well.

摘要： A multilayer parison extruder includes a cylinder; an annular piston movably fitted in the cylinder; a material accumulation chamber in which the piston is moved; a material conduction chamber communicating with the accumulation chamber; an annular multilayer head provided in the conduction chamber; and a die slot provided under the conduction chamber. The extruder further includes a main material extruder for supplying a main material to the accumulation chamber; and auxiliary material extruders for supplying the auxiliary materials to the multilayer head. The extruder is characterized in that pairs of opposed feed ports are provided in the multilayer head and communicate with the auxiliary material extruders. At least one pair of the inlet ports is provided for each of a pair of arc-shaped passages which are for the auxiliary materials. The arc-shaped passages are connected to the feed ports so that each of the arc-shaped passages extends in opposite directions by nearly equal distances from the corresponding feed ports along the circumference of the multilayer head.
