To enlarge the capacity of an apparatus for granulation of plastics by increasing the number of orifices of a die.

Two lines of nozzles 4a and 4b having the open ends in orifices 2 of a die are made to communicate with an introducing groove 3 of each orifice unit 6 and a jacket 7 for temperature regulation is provided between the orifice units 6. First nozzle parts 41a and 41b of small diameters are provided for the nozzles 4a and 4b respectively so as to reduce a dead space wherein the orifices 2 are not disposed due to the presence of the jacket 7, and the jacket 7 is disposed at the position of depth of the nozzle parts. The dead space can be reduced sharply by making the first nozzle parts 41a and 41b eccentric in the directions reverse to each other in relation to second nozzle parts 42a and 42b having the same diameter as the orifices 2.
