Abstract
A multiple fiber spinning apparatus and a method of controlling the same. The apparatus includes an extruding unit, a spin block unit and a spinning nozzle unit. The extruding unit includes extruders that melt, extrude and transfer polymer materials. The spin block unit includes a gear pump unit which has gear pumps connected to each of the extruders. The gear pumps receive the polymer materials from the corresponding extruders and discharge the polymer materials. The spin block unit further includes a flow passage unit which has flow passages connected to the respective gear pumps. The spinning nozzle unit includes spinning nozzles, each of which is connected to one of the gear pumps of each extruder by the corresponding flow passage, so that each spinning nozzle receives the molten polymer materials and spins the polymer materials into a fiber.
