Figure 1 shows the outline of the structure of a conventional extruder, and Figures 2 and 3 show the molten state of resin in the screw groove and the flow of molten resin in the supply section and compression section of the conventional extruder. It is. Figure 4 shows the outline of the structure of the extruder of this invention (the double-mounted screw is omitted), and Figure 5 shows the molten state of the resin in the screw groove and the flow of the molten resin in the compression section of the extruder of this invention. This is what is shown. FIG. 6 shows an example of the arrangement of the ridges of the double ridge type screw of this invention, the molten state of the resin in the grooves, and the flow of the molten resin. 1...
