PURPOSE:To remove difference in blending state between single filaments, by setting a baffle element at the downstream of a static blending element, making arrangement of a spinneret and its extrusion holes into a parallelogram. CONSTITUTION:The molten polymers A and B are introduced from the feed pipes 12 and 13, kneaded by the static blending element 15, the belt of the molten beltlike polymer is made parallel to any one side of the tetragonal spinneret 7 by the baffle element 16. The thickness of the blended beltlike polymer on the spinneret is made constant, and the blended state of single filaments extruded from the spinning nozzles 8A-8D arranged in square becomes almost uniform.
