Method and apparatus for adhesively securing elastic strips under tension to plastics sheet material using hot melt adhesives

摘要

According to the invention of elastic material (4) under tension are adhesively secured to the surface of sheet of plastics material (2) for example, polyethylene, using a strip of extruded melt adhesive. Wherein before contact with the backing sheet the under surface of the adhesive strip is cooled and the elastic strip (4) is then pressed into contact with the uncooled upper surface of the adhesive strip such that the elastic is applied to the adhesive under tension. The invention is particularly applicable to the securing of elastic sealing strips onto the backing sheets of sanitary napkins and pads. IMAGE
