Device for the production of a multicomponent yarn composed of at least two synthetic polymer components

Spinning apparatus for making a multi-component filament comprising a spinneret back plate having first transverse boreholes therein, a spinneret front plate having second transverse boreholes aligned with said first transverse boreholes in said back plate, a spinning orifice aligned with each of said second boreholes and adjacent thereto;

• a feed element for a matrix polymer component extending through each of said first and second boreholes, said feed elements each having a central duct, coaxial with said first and second boreholes, to supply said matrix polymer component to said spinning orifices, at least one feed channel and at least one distribution chamber for at least one other polymer component, each of said distribution chambers being connected to said central duct by a plurality of radial passages through the wall of said feed element, said feed elements having a zone intermediate the ends of said feed elements having a smaller diameter than the diameter of said first and second boreholes and having in said zone said radial passages for the said other polymer component and said radial passages lying in at least two planes perpendicular to the direction of the axis of said central duct.
