Abstract
Aspects of the present invention relate to methods of making an external nasal dilator amenable to continuous and automated manufacture. For example, in one embodiment of the method, a roll of a three-layered material is used as the starting material, the three layers consisting substantially and respectively of (1) a resilient sheet, (2) an adhesive-protecting sheet, and (3) an adhesive layer between the resilient sheet and the adhesive-protecting sheet. A series of dies are used to cut the three-layered material into the appropriate shape and (when necessary) to impress grooves in the resilient sheet.
