<p>PURPOSE: To enable the immediate and convenient change of a die by mutually moving not only the center axis of a charging opening and that of a first die head but also the center axis of the charging port and that of a second die head. CONSTITUTION: In the center axis 34A of a charging opening, the center axis 22A of a first die head passage and the center axis 23A of a second die head passage, when one of the charging opening and the first die head passage is moved to the other one of them, the center axes 34A, 22A are mutually movable and, when the charging opening communicates with the first die head passage, a corresponding shape is imparted to the extrudate issued from the first die head passage. Further, when one of the charging opening and the second die head passage is moved to the other one of them, the center axes 34A, 23A are also mutually movable and, when the charging opening communicates with the second die head passage, a corresponding shape is imparted to the extrudate issued from the second die head passage. As mentioned above, an extrudate altered in a profile shape on the way can be produced.</p> |
