ABSTRACT:
The method of manufacturing an absorbent pad for utilization as a diaper or an adult incontinent brief, wherein a pair of continuous bands of adhesive are applied to the backing sheet of the pad, prior to assembly thereof. The nozzles eject adhesive onto a moving web comprising the backing sheet. The nozzles are shifted sideways during their extrusion of adhesive, from a first location to a second location, thus generating a pair of non-linear bands of adhesive on the backing sheet. The nozzles are again shifted from their second location to their original first location upon receipt of proper signals from a control mechanism. The elastic band is not shifted when the nozzles are, thus effectuating securement of the elastic bands only on the portions of the backing sheets where the adhesive was applied at the first location.
