Method for making smoking article filter

摘要

Two or more rows of fibrous filter material are simultaneously advanced along neighbouring paths through several processing units into a rod forming unit to be converted into filter rods which are ready to be subdivided into filter rod sections of unit length or multiple unit length. At least one of the processing units is designed to simultaneously treat all of the tows.At least one of these treats the tows independently of each other. The tows can be withdrawn from a single source storing a discrete bale for each tow.
