摘要： There is disclosed a method for making a filter element comprising the steps of: advancing two or more sheets of filtering material in a longitudinal direction; separating the two or more sheets of longitudinally advancing filtering material; gathering the separated sheets of longitudinally advancing filtering material to form a partially gathered rod of filtering material having a longitudinally extending recess; inserting an additive release vessel into the longitudinally extending recess; gathering the filtering material around the additive release vessel to close the recess and thereby form a rod comprising a longitudinally extending core of filtering material and one or more additive release vessels.

摘要： There is disclosed a mouth piece, filter element or cooling element for an aerosol generating article comprising: a first section comprising a longitudinally extending core of filtering material having an outer surface and an inner surface, the inner surface defining a channel extending longitudinally from an end of the first section; a second section comprising a longitudinally extending core of filtering material; wherein the first section and the second section are adjacent and integral; wherein the channel has a non-circular transverse cross section which varies in the longitudinal direction by rotating about a longitudinal axis of the first section.
