A method of manufacturing a non-woven material uses 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 spunbonded, melt blown or electrostatic spun techniques for depositing solidify ing 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 facilitates continous production of non-woven articles with three dimensional shapes such as surgical masks or pleated air filters. Additional materials may be added to the non-woven material to bridge between high points of a repeating three dimensional shape to obtain desired properties in a final product. |
