Abstract:
1. An apparatus for manufacturing a three-dimensional netted structure, the apparatus comprising: a mouthpiece to extrude a filament assembly comprising continuous filaments downward; a chute located below said mouthpiece, said chute being inclined so that a width of said chute becomes narrower downward and toward the center of said filament assembly, and a through hole being formed at a center of said chute; a water supplying unit for supplying cooling water to cool said filament assembly downward on a surface of said chute; a water-permeable sheet for covering at least a part of the surface of said chute; fixing members for fixing said water-permeable sheet to said chute; and a pair of drawing-down units located below said chute for conveying the three-dimensional netted structure ejected downward from said chute in water; wherein: said cooling water is supplied to the surface of said chute and is contacted with a surface of said filament assembly to form loops, to contact adjacent continuous filaments to each other, and to entangle adjacent continuous filaments with each other in said filament assembly; a water level in a tank is above a lower end of said chute; and said chute contacts and compresses an entire surface of said filament assembly that is in parallel to a direction in which the filament assembly is extruded.
