Abstract

Устройство для изготовления впитывающего элемента включает в себя формообразующий узел (30), который включает в себя углубленную часть (71) и который обеспечивает осаждение волокна (6), впитывающего жидкости, и полимера (SAP) со сверхвысокой впитывающей способностью в углубленной части (71), придающей определенную форму впитывающему элементу (1), и подающий узел (20), который обеспечивает подачу волокна (6), впитывающего жидкости, и полимера (SAP) со сверхвысокой впитывающей способностью к углубленной части (71). Углубленная часть (71) включает в себя выступающую часть (80), и выступающая часть (80) выступает от нижней поверхности и имеет наклонную поверхность (82) . В сечении, ортогональном к линии гребня выступающей части (80), угол наклона наклонной поверхности (82) относительно поверхности, которая параллельна нижней поверхности, больше угла естественного откоса полимера (SAP) со сверхвысокой впитывающей способностью и меньше 90°.
