Abstract
A device and method for spinning polymer fibers utilizes one or more independent sources of polymer materials, pumps for feeding polymer material from each of the sources, and a series of distribution plates with surface grooves, through holes and/or slots together defining separated distribution paths, each of which receives polymer material from one of said independent sources. The surface grooves are defined to a depth less than the thickness of the distribution plate. At least one distribution plate contains spinneret orifices defined by outlet surface grooves extending from the distribution path to the edge of that plate, whereby fibers are extruded from the spinneret orifices edgewise from the plate. The spinneret orifices may be defined by overlayed outlet surface grooves or slots defined in abutting plates.
