Multilayer coextrusion apparatus and method

The present invention is extrusion equipment (10) containing the method and mutual arrangement block portion which push out a multilayer extrusion thing. A mutual arrangement block portion contains 1st at least two chamber (72), and each 1st chamber contains width, length, height, and an entrance opening (56). The length directions of the 1st chamber are abbreviated parallel mutually. An exit opening is contained in each 1st chamber, an exit opening is large and its height is lower than an entrance opening. A series of 1st distance is defined between the points which met the entrance opening and the exit opening. A die part is contained in extrusion equipment. A die part has a lamination chamber (68) which has height measurement. The height measurement of the lamination is arranged at the abbreviated right angle at the length size of the 1st chamber. The exit is arranged at the end of height measurement. The lamination chamber is arranged so that it may 連通 with the exit opening of the 1st parallel chamber.
