Abstract: A method and apparatus for spinning filaments of a polymeric material includes a first temperature control arrangement (96) for heating a spin pack (24) to a first predetermined reference temperature greater than the predetermined polymer inlet temperature such that the temperature across a polymer filter holder (30) and the spinneret plate (36) in the spin pack (24) is substantially uniform, whereby the temperature of the filaments emanating from the spinneret plate is substantially uniform. A plate assembly (56) having at least one polymer flow passage therein is disposed between the outlet of the pump and the inlet of the spin pack. A second temperature control arrangement (100) for independently controlling the temperature of the plate assembly (56) to a second predetermined reference temperature is provided. The second predetermined reference temperature is selectable to a temperature above, equal to, or below the predetermined polymer inlet temperature, whereby the temperature of polymer conveyed through the polymer flow passage in the plate assembly (56) is selectably controllable to a predetermined polymer temperature lying within a predetermined range of the second predetermined reference temperature.
