Provided is an apparatus for producing a three-dimensional net structure enabling resilience, dimensional accuracy, and other attributes to be adjusted in a simpler and more cost-effective manner. An apparatus (1) for producing a three-dimensional net structure, wherein the apparatus is characterized in having: a spinneret (3) having an extrusion hole (31) through which a molten thermoplastic synthetic resin is discharged downward as a filament grouping (21) comprising a plurality of filaments (20); a pair of chutes (42a, 42b) having inclined surfaces (44a, 44b) arranged on either side of lengthwise surfaces (22a, 22b) of the filament grouping (21), and inclined towards the filament grouping (21), the chutes being arranged opposite each other across a space (S1) smaller than the widthwise length of the extrusion hole (31); a water supply port (5) for supplying coolant water to the inclined surfaces (44a, 44b); and a pair of pulling devices (6) that have endless belts (61a, 61b) for pulling the filament grouping (21) while in contact with the lengthwise surfaces (22a, 22b) of the filament grouping (21), and that are arranged opposite each other across a space smaller than the space between the pair of chutes (42a, 42b). |
