Abstract
Aspects of the methods and apparatuses relate to making elastic laminates, and more particularly, methods and apparatuses for applying elastic material in a curved path onto an advancing substrate. The elastic material may be in various forms, such as for example, elastic strands and/or ribbons. Apparatuses and methods disclosed herein may also provide for the application of viscous fluids, such as adhesives, in pre-determined patterns to the elastic material while being positioned on an advancing substrate.
