摘要

An apparatus for the production of filamentary filters for filtering tobacco smoke from fine denier filaments, apparatus comprising a number of elements in combination; a) means for continuously extracting a polymerizable, synthetic, plasticized crimped material from a power source thereof; b) means for forming the tow in a relatively flat band or tape; c) means to prestress the tow and remove secondary curls from it; d) means for mechanically separating the filaments of the tow from one another by longitudinally deploying the filaments; e) a second means for further deploying the tow to a constant and uniform width; f) means for applying a thin and uniform layer of liquid plasticizer to both surfaces of the tow band; g) means for more uniformly separating the filaments and evenly distributing the plasticizer therein; and h) means for forming the plasticized tow into a substantially tubular filter for filtering tobacco smoke.
