Device for manufacturing filament three-dimensional bonded member

A device for manufacturing a filament three-dimensional bonded member, the device comprising:

• a molten filament supply unit that discharges a molten filament group formed with a plurality of molten filaments downward in a vertical direction;
• a chute that includes a chute inclined plate which receives the molten filament at an end in a thickness direction of the molten filament group and displaces the molten filament group in such a direction as to reduce a thickness of the molten filament group;
• a cooling water supply unit that supplies cooling water to the chute inclined plate;
• and
• a fusing formation unit that three-dimensionally entangles the molten filaments and simultaneously fuses contact points,
• wherein a plurality of grooves are formed in an upper surface of the chute inclined plate,
• a width of each of the plurality of grooves is equal to or greater than 0.1 mm and equal to or less than 3.0 mm,
• a depth of each of the plurality of grooves is equal to or greater than 0.1 mm and equal to or less than 3 mm and
• a distance between the grooves adjacent to each other is equal to or greater than 1 mm and equal to or less than 7 mm.
