INJECTION OF A MEDIUM INTO A FILTER SEGMENT

摘要

The method of manufacture of a multiple segment filter for smoking articles has the filter segments (1,7) in one group joined to form a filter. A carbon filter material or scent can be injected into the filter after the segments have been cut. The material can be injected (5) during transport of the filter segments, particularly when on the feed drum (18). Claims include a filter manufacturing machine module using the method.
