Abstract (en)
The present invention provides a melt spinning apparatus that executes spinning so as to obtain a uniform multifilament yarn having a uniform fineness. <??>A melt spinning apparatus includes a plurality of spinning packs 2 installed in a pack housing 33 contained in a spinning beam 1, the spinning packs 2 being arranged in a line, an integral cooling wind supply box 15 provided below the plurality of spinning packs 2 so as to be shared by the spinning packs 2, and filament cooling cylinders 44 each comprising cylindrical filters 8 and 9 and provided inside the cooling wind supply box 15 in association with the respective spinning packs. The melt spinning apparatus is characterized in that a first seal mechanism is used to seal a top portion and a bottom portion of each of the filament cooling cylinders 44 from a top plate and a bottom plate, respectively, of the cooling wind supply box 15, and a second seal mechanism 20 is used to seal the top portion of the filament cooling cylinder 44 from a bottom surface of the pack housing 33 via spacers 5 and 35 (Fig.1). <IMAGE>
