Abstract

PURPOSE:To mold a laminated body consisting of a plurality of layers containing different compounding agents efficiently by a method wherein a cylinder is made by a double cylindrical construction and a conduit for adding the compounding agent is provided on an inner cylinder. CONSTITUTION:A cylinder in a zone after which fusion of resin is finished is made by a concentric double cylindrical construction and a conduit 4 for adding compounding agent is provided on an inner cylinder 3. The resin finished the fusing thereof is flowed into separated two paths and a portion thereof forms an outside resin layer 13 after it is passed through an outside area of the inner cylinder 3 while the balanced resin forms an inside resin layer 10 after it is passed through an inside of the inner cylinder 3 and mixed with a variuous kinds of the compounding agents added from the conduit 4. A flowing pattern may be formed by utilizing a coloring material as the compounding agent.
