Abstract

PURPOSE:A multiple simultaneous extrusion coater capable of easily adjusting thickness deviation, wherein plural core wire inserting pipes are provided in the nipple rotatably and movably in the axial direction. CONSTITUTION:A molten material, e.g. rubber or plastic, etc. is extruded through the clearance between the die 2 and nipple 4 at the extruder head 1 on the plural core wires 6 by the simultaneous coextrusion. The plural core wire inserting pipes 8 provided at the nipple 4 are moved rotatably in the axial direction respectively, thus adjusting the thickness deviation of the plastic, etc.
