Abstract

PURPOSE:To mold a laminated body consisting of a plurality of layers containing different compounding agents efficiently by a method wherein a tubular hole for flowing fused resin along an axial line of a screw is provided while a hole for adding the compounding agent is provided on a cylinder. CONSTITUTION:A tubular hole 2 in a screw 1 is penetrated from an opening 3 provided in a screw groove 6 at a position after which fusion of resin is finished to a tip end of the screw. A hole 4 for adding compounding agent is arranged at a position nearer to a tip end of a cylinder than the position of the opening 3. The resin finished fusing thereof is flowed into two different paths and a part of it forms an inside resin layer 15 via the tubular hold 2 while the balanced part of resin forms an outside resin layer 14 after it is mixed with various kinds of the compounding agents added from the adding hole 4. Any of liquid, solid or gaseous compounding agent may be used and a flow pattern may be molded by utilizing a coloring material as the compounding agent.
