Apparatus for making composite filters |
摘要 |
Filter material is formed into a continuous rod without wrapping and divided into first filter portions which are then spaced apart whilst moving axially. These first filter portions are intercalated with a stream of spaced second filter portions to form an alternating stream which is then continuously wrapped to produce composite filter rod. The resulting composite filters obtained from this rod include less wrapper material than in conventional construction.
