Abstract (en)

[origin: EP3488711A1] A filter manufacturing apparatus 1 includes a transfer path 30 through which filter elements WF for a smoking article is transferred, and an additive feeding unit 36 provided immediately above the transfer path 30 to feed a granular additive AC to each of the filter elements WF or among the filter elements on the transfer path 30. The additive feeding unit 36 includes a classifier 38 classifying the additive AC into coarse grains CG and fine grains FG based on granularity to remove the fine grains FG immediately before feeding the additive AC to each of the filter elements WF or among the filter elements.
