ABSTRACT:
A method of manufacturing a non-woven material using a contoured honeycomb drum with an outer microporous surface, more particularly with a contoured outer surface, for the manufacture of contoured non-woven fibrous materials. The method can use spunbond or melt blown techniques for depositing solidifying filaments on the microporous surface such that the non-woven material conforms to the contour of the drum, and then removing the non-woven material from the drum. The drum of the current invention facilitates continuous production of non-woven articles with three dimensional shapes such as surgical masks or pleated air filters.
