APPARATUS FOR MANUFACTURING THREE-DIMENSIONAL FILAMENT CONJUGATE, METHOD FOR MANUFACTURING THREE-DIMENSIONAL FILAMENT CONJUGATE, AND MATTRESS CORE MATERIAL

摘要

The present invention is a manufacturing apparatus and manufacturing method for manufacturing a three-dimensional filament conjugate. The apparatus is provided with: a divided body weight information-acquiring means for associating divided body weight information, in which body weight distribution in the height direction of a person is divided in the direction of the height axis, with distances from the top of the person's head and recording same; and a three-dimensional conjugate-forming means for intertwining filaments of a thermoplastic resin material extruded from an extruder in a three-dimensional network and fusing same to form a three-dimensional filament conjugate that is long in the product flow direction. The three-dimensional conjugate-forming means comprises a filament density-controlling means for controlling filament density in the product flow direction of the three-dimensional filament conjugate on the basis of the divided body weight information. As a result of said configuration, it is possible to quickly, reliably and efficiently manufacture products of desired specifications for customers seeking merchandise of made-to-order specifications.
