ABSTRACT:
A method of continuously producing a melt-blown polymer filament mass includes producing a first set of melt-blown polymeric filaments, collecting the first set of filaments on a rotating collection device to form a tubular filament mass having a plurality of layers, and applying a second set of melt-blown polymeric filaments to the filament mass. The first set is produced generally in-line along an axis generally parallel to the collection device. The second set is deposited on the filament mass such that filaments of the second set extend through and engage a plurality of layers of the filaments of the first set. The method further includes urging the filament mass along the collection device to create a tubular filament mass of indefinite length with a first major surface and a second major surface. In one embodiment, the second set are applied in a sweeping motion.
