SOUND-ABSORBENT AND MANUFACTURING METHOD USING THE SAME

摘要

An apparatus for manufacturing a soundproof agent, according to the present invention, is capable of manufacturing a various types of webbed forms of a soundproof agent, since a molten-foamed molten resin and a filament are solidified in a mixed status. The soundproof agent can comprise at least two layers. At least one layer has continuously formed curvatures to absorb a wide range of frequency.
