Abstract
An absorbent article comprising a cover sheet and a backing sheet, the cover and backing sheets being attached in areas without the use of water-insoluble adhesives to form pockets in which a fluid absorbent material is stored. The absorbent article is formed by depositing portions of the fluid absorbent material on the backing sheet, placing the cover sheet over the absorbent material and the backing sheet, and pressing the cover sheet towards the exposed parts of the backing sheet to cause bonding of the fibers in each sheet and attaching the cover sheet to the backing sheet to form pockets in which the absorbent material is stored.
