Abstract
A method of manufacturing a multi-layered web uses contoured honeycomb drums for the manufacture of non-woven webs used to make the multi-layered web. The method can use spunbonded, melt blown, or electro-static spun techniques for depositing solidifying filaments on outer collection surfaces of a multi-drum system. The multi-drum system may be employed to improve multi-layered web uniformity and the overall quality of the multi-layered web by presenting a single optimal collection surface for each independent web layer being produced.
