Abstract
A method of extruding two or more closure elements onto a web includes extruding the closure elements through a die plate having a first aperture for a first closure element and a second aperture for a second closure element. The first aperture is spaced from and at least partially overlaps the second aperture in a lateral direction. The partial overlapping of the apertures allows the closure elements to be spaced very closely together on the web. The space between the apertures prevents extrudate streams forming the elements from bonding to each other. The closely spaced elements are extruded through the same die plate without an interconnecting portion therebetween.
