Abstract
A spunbond system for manufacturing a non-woven web of fibers includes a spin beam assembly configured to process and deliver a plurality of polymer streams for extrusion through spinneret orifices. The spin beam assembly includes a plurality of manifold sections within the spin beam assembly, each manifold section including a distribution pipe configured to transfer a respective polymer component to a plurality of piping sections extending within the manifold section and a heat transfer medium that flows within the manifold section and around the piping sections extending into the manifold section so as to maintain the respective polymer component at a selected temperature. The system further includes a quenching zone configured to receive and quench extruded filaments from the spinneret orifices, a drawing unit in communication with the quenching zone and configured to receive and attenuate the quenched filaments, and a forming surface configured to receive drawn filaments emerging from the drawing unit and form a non-woven fibrous web on the forming surface.
