PROBLEM TO BE SOLVED: To express comparatively clear pattern without remarkably lowering strength of a raw plastic molding by providing a plurality of biting protrusions bitten in a surface desired to form a surface pattern on a patterning unit for forming a surface pattern on molding raw material extruded from a mold. SOLUTION: A resin molding apparatus for extrusion molding kneaded resin material comprises a patterning unit 20 for forming a surface pattern of a molding raw material 10 to be extruded from a mold 30. The unit 20 provides, for example, nine biting protrusions 21 bitten in a surface desired to form the pattern on the material 10. The part 21 is formed in a bard-like state, and its interval is, for example, 10mm in a direction perpendicular to an extruding direction. The unit 20 is fixed to the apparatus so as not to move to the mold 30. Accordingly, the mold 30 and the material 10 extruded from the mold 30 are relatively moved. |
