The apparatus has at least one dosing pump (10), at the spinning unit (5), to deliver pigments in a liquid or paste form, to color the filaments (Y). The pigment dosing pump (10) is . Apparatus for melt spinning synthetic filaments (Y) has at least one extruder (1), at least one spinning unit (5) with at least one spinning pump (6) and a spinning head (7), and spinneret (8). The assembly has at least one dosing pump (10) to deliver pigments in a liquid or paste form, to color the filaments (Y). The pigment dosing pump (10) is at the spinning unit (5). Preferred Features: The dosing pump (10) is directly in front of each spinning pump (6), with a pigment dosing pump (10) for each spinning pump (6). A channel (11) with a heater (12) links the pigment dosing pump (10) with the channel which carries the molten filament material. Each spinning pump (6) has a mixer (13), after or integrated with it, as a static or dynamic mixer. Each spinning pump (10) is a geared pump. |
