PROBLEM TO BE SOLVED: To provide a method for extrusion-molding resin molding which makes an efficient extrusion operation by shortening a time required for preparatory arrangement extrusion-mold resin moldings with different shapes.SOLUTION: A die 2a for replacement is on standby in a position adjacent to a die 2 installed on extruder 1, and a sizing unit 36 for replacement is on standby next to a sizing unit 35 in line with the extrusion line a of sizing device 3. When the extruder is stopped after completing extrusion, the die 2a for replacement is installed on the extruder 1 to replace the die, the sizing unit 36 for replacement is made in line with the extrusion line a of the sizing device 3 to replace the sizing unit, and upper and lower endless rotary bodies 41 of a take-up device 4 are laterally moved in a direction orthogonal to the extrusion line a to make either of the supporting faces 40a of pads 40 in line with the extrusion line a replace the take-up device 4. Then the extrusion molding is performed. |
