Abstract: An apparatus for manufacturing a nonwoven fabric has a spinning mechanism having a plurality of nozzles for extruding filaments, and a conveyor for collecting and delivering the extruded filaments. Between the spinning mechanism and the conveyor, there are disposed a high-speed air stream generating mechanism for generating a high-speed air stream to carry the filaments extruded from the nozzles to attenuate the filaments, and an air stream vibrating mechanism for periodically changing the direction of the high-speed air stream in the machine direction of the conveyor.

Abstract: A melt spinning apparatus particularly applicable to a multifilament spinning for pitch based carbon fibers. The melt spinning apparatus is provided in which a flow uniforming member is attached to a central part on a spinning side of a spinneret having circularly or concentrically arranged nozzles, the flow uniforming member having a sectional diameter at least 3 mm smaller than the diameter of the innermost row of nozzles and a length not smaller than 2 cm. The apparatus is provided with a cooling means as an outer peripheral portion below a spinning pack having an annular blowing port for blowing a cooling gas toward the spun filaments. A gap is provided between the spinning pack and the cooling means and is sealed with a heat insulator.

Abstract: A melt-spinning nozzle in which is disposed an elongated molded piece so as to form a space serving as a melt flow path between the elongated molded piece and the inner wall of the nozzle.
