ABSTRACT:
A doormat manufacturing apparatus contains a spinning pack having a plane rectangular shape for spinning a large number of monofilaments, a plurality of extruders disposed at symmetrical positions in the longitudinal direction of the spinning pack for supplying a plurality of molten synthetic resins to the spinning pack, and a collecting mechanism for collecting monofilaments discharged from the spinning pack. The spinning pack contains a resin flowpath changeover unit arranged over a multihole nozzle plate, and the resin flowpath changeover unit is connected to each extruder by a respective communicating pipeline. The communicating pipelines are arranged at symmetrical positions in the longitudinal direction of the spinning pack. The resin flowpath changeover unit has a plurality of longitudinally extending main flowpaths, each of which communicates with a respective communicating pipeline via a respective zone flowpath and with a respective branch flowpath extending crosswise from the main flowpath. The pluralities of branch flowpaths substantially cover the surface of the resin flowpath changeover unit, and the multihole nozzle plate has a nozzle hole in communication with each branch flowpath.
