Two rows of nozzles 4a and 4b whose open ends are formed as orifices 2 of a die are respectively made to communicate with introducing slots 3 of orifice units 6, and jackets 7 for temperature regulation are each disposed between the orifice units 6. First nozzle portions 41a and 41b of a small diameter are provided in the nozzles 4a and 4b for the purpose of reducing a dead space where the orifices 2 cannot be disposed due to the jackets 7, and the jackets 7 are disposed at their depthwise position. The first nozzle portions 41a and 41b are disposed eccentrically in mutually opposite directions with respect to second nozzle portions 42a and 42b having the same diameter as the orifice 2, thereby making it possible to substantially reduce the dead space. <IMAGE> |
