ABSTRACT:
A machine for applying continuous bands of adhesive generally longitudinally along an absorbent pad, which pad may comprise a diaper or an adult incontinent brief. The machine includes a pair of adhesive ejecting nozzles which direct adhesive onto the backing sheet of the pad as the sheet is moved therepast. The nozzles are intermittently directed to their respective sides, under control of a counting apparatus, so as to effectuate a pair of non-linear bands of adhesive onto the sheet. A pair of elastic bands are guided onto the sheet so as to attach themselves only in intermediate portions of the adhesive bands on the backing sheet. The nozzles are also withdrawable from the backing sheet when the sheet is not moving, so as to prevent their burn through. The nozzles movement is controlled by piston and cylinder units under solenoid regulation, which has received signals from the counting apparatus.
