摘要
An apparatus for producing meltblown webs includes a meltblowing die having a plurality of filament outlets, a collector for receiving filaments of polymeric material expelled from the filament outlets, and a first Coanda effect device positioned adjacent to the path of the filaments adjacent to the last filament outlet at an end of the meltblowing die. Methods of forming meltblown webs using such an apparatus are also disclosed.
