PURPOSE:To manufacture continuously a plurality of kinds of continuous resin molded products by simple operation in a short time by extruding resin in a manner of pinching addition sections between common sections of respective molded products, selecting the additional sections and fusion welding integrally common sections each other. CONSTITUTION:An extrusion molding machine 12 shuts first resin 13a extruded out of a first extruder and extrudes first and second common sections 11a and 11b. Also, second resin 13b extruded out of a second extruder is extruded between the common sections 11a, 11b as an additional section 11c. The common sections 11a, 11b and the additional section 11c are pressed by a roller 16 to take off an integrated extruded material 11 to manufacture a first molding 1a. On the other hand, only common sections 11a, 11b are extruded, and a pressed, integrally welded extruded material 11 is taken off to manufacture a second molding 11b without the additional section 11c and with a short foot section 5b. Thus, a plurality of kinds of resin molded products 1a, 1b can be manufactured continuously by simple operation in a short time by using one extrusion mold 12. |
