する押出機用ヘツド装置。 By providing a cylindrical flow path nozzle consisting of a die core and a die outer cylinder via a die holder and a breaker plate on the discharge side of a twin-screw extruder, the extruded material is formed into a cylindrical shape, and this is open-cut. In an apparatus for obtaining a sheet-like extruded product, an equalizing chamber for supplying a filler material, which is parallel to the main material passing through the breaker plate, is attached to the adapter that is located on the rear surface of the die holder and holds the breaker plate, and is in contact with the outer periphery of the breaker plate. The breaker plate is formed into an annular cylindrical shape, and is provided with a material injection port into the chamber, and one end thereof communicates with the chamber and the other end opens toward the cylindrical flow path nozzle on the downstream end surface of the breaker plate. A head device for an extruder, characterized in that a required number of filler material supply grooves are provided radially.
