Abstract
A manufacturing apparatus and manufacturing method for manufacturing a three-dimensional filaments-linked structure includes: divided weight information acquisition means which records divided weight information acquired by dividing weight distribution in a height direction of a person in a height axis direction, in correlation with a distance from a top of a head of the person; and three-dimensional linked structure formation means which tangles and fuses filaments of a thermoplastic resin material extruded from an extruder in a three-dimensional net shape, and forms a three-dimensional filaments-linked structure which is long in a product streaming direction, and the three-dimensional linked structure formation means includes filament density control means which controls filament density in the product streaming direction based on the divided weight information. As a result of the configuration, it is possible to promptly, reliably, and efficiently manufacture products with desired specifications for customers who request products with made-to-order specifications.
