Japanese Patent JP5145499
Kind Code:

To provide a method and an apparatus for manufacturing rationally a profile curved molded article which can form a complicatedly curved profile extrusion-molded article rich in variation, and can take off an extruded molding raw material without collapsing of the shape when a plastic material is extruded.

By horizontally shaking and turning at an arbitrary angle the direction of a movable mouthpiece part 21 of a rotating die 2 in an extruder 1 to the central axis in the extruding direction of the extruder, the molding raw material m is extruded obliquely at a curvature corresponding to the horizontally shaking angle from the movable mouthpiece part 21 to mold a curved part. The molding raw material m extruded while the curved part is molded like this, is carried on a taking-off table 3 freely movable in three axes XYθ driven synchronously in the same direction and at the same speed as the direction and the speed which the movable mouthpiece part 21 directs and extrudes, and is received and guided to convey in accordance with the extruding direction and speed.
