A closed fiber spinning system includes a spin beam assembly including a plurality of polymer distribution manifolds to independently deliver different polymer component fluid streams to a spin pack and independently maintain those fluid streams at different temperatures. The spin beam assembly in combination...http://www.google.es/patents/US7179412?utm_source=gb-gplus-sharePatente US7179412 - Method and apparatus for producing polymer fibers and fabrics including multiple polymer components in a closed system
