Abstract
The object is to improve the production efficiency of three-dimensional net-like structures while maintaining the surface quality of the three-dimensional net-like structures. A second chute 6 is located below a hole-free region 33 and is provided between first chutes 4a and 4b. Filaments 20a and 20b located on longitudinal sides 22b and 22c at the periphery of assemblies 21a and 21b are in contact with the upper side of inclined surfaces 46a and 46b of the second chute 6. Such contact disturbs the vertical fall of the filaments 20a and 20b and causes the filaments 20a and 20b to be tangled in loops with the adjacent filaments 20a and 20b and pass through the first chutes 4a and 4b and the second chute 6, while being cooled down with water supplied from openings 51a, 51b and 51c.
