Title:
APPARATUS FOR PRODUCING FILAMENTOUS THREE-DIMENSIONAL BONDED BODY
Document Type and Number:
WIPO Patent Application WO/2024/071296
Kind Code:
A1
Abstract:
Provided is a production apparatus that can form a more uniform filamentous three-dimensional bonded body, and that can do so without a reduction in the bonding strength at the melt-bonding points between molten filaments. This apparatus for producing a filamentous three-dimensional bonded body comprises: a molten filament supply part that discharges a molten filament group downward; a chute having an inclined chute plate that receives the molten filaments at the thickness direction edge of the molten filament group, gathering same in a direction that reduces that thickness; a cooling water supply part that supplies cooling water to the inclined chute plate; and a melt bond formation part that brings about three dimensional intertwining of the molten filaments while at the same time bringing about melt bonding of points of contact. In this apparatus, a plurality of grooves are formed on an upper surface of the inclined chute plate; the width of each of the plurality of grooves is 0.1-3.0 mm; the depth of each of the plurality of grooves is 0.1-3 mm; and the distance between the adjacent grooves is 1-7 mm.
