Abstract
An absorbent core forming apparatus (10) for manufacturing an absorbent core containing a highly absorbent polymer, wherein the absorbent core forming apparatus (10) includes: a conveying section (11) for conveying a substrate sheet (1K) in a conveying direction; a particle supply section (12) for supplying highly absorbent polymer particles (12S) toward the substrate sheet (1K); and an adhesive ejection section (15) disposed downstream of the particle supply section (12) in the conveying direction, for ejecting adhesive (15H) together with an airflow toward the substrate sheet (1K), wherein the adhesive ejection section (15) uses the adhesive (15H) ejected from the adhesive ejection section (15) to push at least a portion of the highly absorbent polymer particles (12S) that bounce off the substrate sheet (1K) back toward the substrate sheet (1K).
