Apparatus for producing composite textile filaments from a plurality of synthetic polymers

Claim 1

AN APPARATUS FOR PRODUCING COMPOSITE TEXTILE FILAMENTS FROM A PLURALITY OF HEAT-FUSIBLE, FIBER-FORMING, SYNTHETIC POLYMERS, COMPRISING A PLURALITY OF POLYMER MELTING UNITS, EACH ADAPTED TO RECEIVE A HEAT-FUSIBLE, SYNTHETIC, FIBER-FORMING POLYMER AND TO PROVIDE A CONTINUOUS MELT THEREOF INTO A DISTRIBUTING SYSTEM ADAPTED TO DIVIDE THE MOLTEN STREAM FROM SAID MELTING UNIT INTO A PLURALITY OF SUBSTREAMS, A PLURALITY OF METERING PUMPS, A PLURALITY OF SPINNERET ASSEMBLIES, CONDUIT MEANS ASSOCIATED WITH SAID DISTRIBUTING SYSTEM, METERING PUMPS AND SPINNERET ASSEMBLIES WHEREBY MOLTEN POLYMER FROM THE DISTRIBUTING SYSTEM FOR EACH MELTING UNIT IS CONVEYED TO A PLURALIYT OF METERING PUMPS AND WHEREBY EACH METERING PUMP IS CONNECTED TO AT LEAST ONE SPINNERET ASSEMBLY, THE ARRANGEMENT OF SAID PUMPS AND CONDUIT MEANS BEING SUCH THAT EACH SPINNERET ASSEMBLY RECEIVES A STREAMLET OF MOLTEN POLYMER ORIGINATING IN EACH OF SAID POLYMER MELTING UNITS, SAID CONDUIT MEANS BEING INDIVIDUALLY SO SHAPED AND PROPORTIONED AS TO GIVE ALL THE MOLTEN STREAMLETS THROUGH CORRESPONDINGLY LOCATED CONDUITS THE SAME LENGTH OF TRANSIT TIME, AND HEATING MEANS ASSOCIATED WITH SAID APPARATUS TO MAINTAIN THE MOLTEN STREAMLETS FLOWING FROM ANY PARTICULAR MELTING UNIT AT THE SAME TEMPERATURE AT ALL MUTUALLY CORRESPONDING POINTS ALONG THE PATH OF FLOW OF ANY OF THE POLYMERS FROM SAID MELTING UNIT TO THE LEVEL OF SAID PLURALITY OF SPINNERET ASSEMBLIES.

Claim 2

AN APPARATUS FOR PRODUCING COMPOSITE TEXTILE FILAMENTS FROM A PLURALITY OF HEAT-FUSIBLE, FIBER-FORMING, SYNTHETIC POLYMERS, COMPRISING A PLURALITY OF POLYMER MELTING UNITS, EACH ADAPTED TO RECEIVE A HEAT-FUSIBLE, SYNTHETIC, FIBER-FORMING POLYMER AND TO PROVIDE A CONTINUOUS MELT THEREOF INTO A DISTRIBUTING SYSTEM ADAPTED TO DIVIDE THE MOLTEN STREAM FROM SAID MELTING UNIT INTO A PLURALITY OF SUBSTREAMS, A PLURALITY OF METERING PUMPS, A PLURALITY OF SPINNERET ASSEMBLIES, CONDUIT MEANS ASSOCIATED WITH SAID DISTRIBUTING SYSTEM, METERING PUMPS AND SPINNERET ASSEMBLIES WHEREBY MOLTEN POLYMER FROM THE DISTRIBUTING SYSTEM FOR EACH MELTING UNIT IS CONVEYED TO A PLURALIYT OF METERING PUMPS AND WHEREBY EACH METERING PUMP IS CONNECTED TO AT LEAST ONE SPINNERET ASSEMBLY, THE ARRANGEMENT OF SAID PUMPS AND CONDUIT MEANS BEING SUCH THAT EACH SPINNERET ASSEMBLY RECEIVES A STREAMLET OF MOLTEN POLYMER ORIGINATING IN EACH OF SAID POLYMER MELTING UNITS, SAID CONDUIT MEANS BEING INDIVIDUALLY SO SHAPED AND PROPORTIONED AS TO GIVE ALL THE MOLTEN STREAMLETS THROUGH CORRESPONDINGLY LOCATED CONDUITS THE SAME LENGTH OF TRANSIT TIME, AND HEATING MEANS ASSOCIATED WITH SAID APPARATUS TO MAINTAIN THE MOLTEN STREAMLETS FLOWING FROM ANY PARTICULAR MELTING UNIT AT THE SAME TEMPERATURE AT ALL MUTUALLY CORRESPONDING POINTS ALONG THE PATH OF FLOW OF ANY OF THE POLYMERS FROM SAID MELTING UNIT TO THE LEVEL OF SAID PLURALITY OF SPINNERET ASSEMBLIES.
