ABSTRACT:
Multilayer meltblown fibrous webs, as well as apparatus and methods of forming the webs. The webs are produced on a rotating collector that also moves parallel to its longitudinal axis. The webs are thus formed in a helical process, and the resulting tubular web is separated in a direction parallel to a helix angle. By separating the tubular web in a direction parallel to the helix angle, a flat multilayer meltblown fibrous web is provided that allows for incorporation of feathered edges formed during the article's manufacture.
