Claims
- 1. A method for manufacturing an absorbent member which has a liquid permeable covering sheet and a reticulated sheet for covering an absorbent core and is adapted to be interposed between a liquid permeable topsheet and a liquid impermeable backsheet of an absorbent article, said method comprising the steps of:
- (a) applying to a continuously delivered, thermoplastic synthetic resin sheet a number of slits arranged in a moving direction of said resin sheet in a predetermined pattern;
- (b) stretching said resin sheet to form said reticulated sheet having a transverse central region having large size openings created by said slits to define a relatively high open ratio and transverse opposite side regions having smaller size openings relative to the large size openings and also created by said slits to define a relatively low open ratio;
- (c) locating said central region of the reticulated sheet over a central region of said absorbent core to cover said absorbent core; and
- (d) covering said absorbent core and said reticulated sheet with said covering sheet.
- 2. The method of claim comprising the further step of heat-bonding said reticulated sheet to one of said absorbent core and said covering sheet.
- 3. The method of claim 1, wherein said reticulated sheet is a laminated three-layer sheet which comprises a central layer sheet having a relatively higher melting point, upper and layer sheets having melting points lower than the melting point of said central layer.
