Abstract
A compact melt spinning apparatus having a screw-type extruder or extruders is provided. A metering pump or pumps, a molten polymer conduit or conduits and a spinning pack or packs and optionally the barrel(s) of the extruder(s) are positioned inside a heating frame encased in a casing of a thermal insulation material. The conduit(s) is arranged on a horizontal plane located above the spinning pack(s), and the extruder(s) and the metering pump(s) are arranged in a horizontal line and located above the conduit(s).
Claims11
An apparatus for melt spinning a fiber-forming synthetic polymer comprising at least one screw-type extruder for melting and extruding the synthetic polymer, at least one metering pump for metering the synthetic polymer, a plurality of spinning packs arranged in a horizontal line parallel to the axis of the extruder and directly beneath the extruder and a plurality of conduits for permitting the molten polymer to pass therethrough from the metering pump to each spinning pack, characterized in that
- the metering pump, the spinning packs and the conduits are positioned inside a heating frame provided with a heating means;
- said heating frame being encased, together with the portion of the extruder to be heated, in a casing of a thermal insulation material;
- and
- the conduits extend on a substantially horizontal plane located above the spinning packs and beneath the extruder;
- and the extruder and the metering pump form a substantially horizontal line.
