ABSTRACT:
A method of applying adhesive to the heat shrinkable, waist elastic member of a disposable garment, and for attaching the elastic member to the backing sheet of the gartment, comprises extruding an adhesive bead from an adhesive dispenser and impacting the bead with jets of air directed substantially tangent to the periphery thereof to form an elongated adhesive fiber and to impart a twisting motion to the adhesive fiber. The adhesive fiber is deposited in a spiral pattern onto the heat shrinkable elastic member, preferably at an application temperature which substantially reduces activation of the heat shrinkable elastic member. The elastic member is cut into individual strips which are adhered at longitudinally spaced locations to the material forming the backing sheet of the disposable garment.
