Abstract:
A drawing unit for producing a non-woven fabric web, comprising:a plurality of slits through which a plurality of filaments are drawn, each of the plurality of slits having an inlet end and an outlet end, the filaments being generated from a spinneret and then divided between the inlet ends of the plurality of slits so as to prevent tangling of the filaments; means for generating suction at the inlet ends of the plurality of slits and air current to move the plurality of filaments through the plurality of slits and out of the outlet ends thereof; and a collecting conveyor for collecting the filaments blown out from the outlet ends of the plurality of slits so as to form the non-woven fabric web, wherein the plurality of slits extend in a widthwise direction of the collecting conveyor, and substantially perpendicular to a direction of movement of the collecting conveyor, the outlet ends of the plurality of slits being formed so as to adjustably combine the air currents from the outlet ends to uniformly scatter the plurality of filaments onto the collecting conveyor.
