A melt spinning apparatus adapted for spinning a plurality of preferably monofilaments each having a denier which is maintained within close tolerances. The apparatus comprises a nozzle head having a plurality of vertical bores which are annularly arranged about a central axis and a nozzle assembly in each of the bores. A separate melt delivery system delivers pressurized melt to each nozzle assembly, and in a preferred embodiment, each separate melt delivery system comprises one of the discharge outlets of a planetary gear pump.

Melt spinning apparatus and method

A spinning apparatus for melt spinning thermoplastic multicomponent yarn is disclosed, in which a nozzle pack (22) is joined by bolts with a filter cup (13), with the entire unit being mounted by a thread (21) on a connecting plug (20) of the pump or distributor block (10). The nozzle pack (22) is adapted to produce bicomponent yarns, and the exchange of a single blending plate (37) allows the apparatus to produce different structures of bicomponent filaments. Such spinning apparatus enhance the flexibility of the synthetic fiber producer and reduce the cost for spare parts, since it is necessary to keep available only additional blending plates (37), but not entire nozzle packs (22).
