Abstract
A method for manufacturing an absorbent article including: a topsheet formed from a nonwoven fabric; a backsheet; and a cushion layer disposed between the topsheet and the backsheet is achieved by applying heat to a cushion layer unwound from a material roll to restore the bulkiness of the tissue layer, blowing air into the cushion layer for rapid cooling after the application of heat to maintain the restored bulkiness of the cushion layer, and laminating the topsheet, cushion layer, and the backsheet onto each other.
