Abstract
An object of the present invention is to provide a dispersing device which can disperse filaments uniformly and widely on a moving collector surface by suppressing the turbulence of an air flow as a carrier medium for the filaments to thereby reduce the disturbance of the filaments. The dispersing device (1) of the present invention is formed as a dispersing pipe consisting of a pair of dispersing plates (2) vertically extending so as to be opposed to each other and a pair of side plates (3) connecting the dispersing plates. The dispersing pipe has an upper end formed with a filaments inlet and a lower end formed with an oblong filaments outlet (5) surrounded by the dispersing plates and the side plates. The dispersing pipe has a shape such that a space t between the dispersing plates is decreased with an increase in distance z from the filaments inlet toward the filaments outlet (5), and that a space w between the side plates is increased with the increase in the distance z. According to the dispersing device of the present invention, the turbulence of the carrier air flow is reduced to thereby uniformly and widely disperse the filaments on the moving collector surface (14). Accordingly, a web having a good appearance with less nonuniformity and less yarn bundles can be obtained.
