摘要:
A method and an apparatus are provided for making a disposable bodily fluid handling composite pad having thickness-reduced regions on longitudinally opposite ends. The disposable bodily fluid absorbing composite pad includes a bodily fluid absorbing first pad and a bodily fluid absorbing second pad seperably attached to the first pad. A continuous web having continuous bodily fluid absorbing layer and bodily fluid impervious layer permanently attached together is fed to pass through paired compression rolls to obtain a worked web formed in regions which will become ends of the first pad with thickness-reduced regions. A bodily fluid absorbing web is seperably attached to the worked web to obtain a first composite web. A bodily fluid impervious web, pressure-sensitive adhesive and a separator are placed on the bodily fluid absorbing web of the first composite web to obtain a second composite web from which the composite pad is cut out.
