Abstract
Improvements relating to composite filter rods, for producing composite filters for attachment to cigarettes, are obtained by partially enclosing a stream of spaced filter portions in a continuous wrapper so that pockets between the filter portions for receiving granular filter material are particularly well-defined. The material is introduced into the pockets through a relatively narrow opening defined on one side by the free edge of one side of the wrapper and on the other side by a longitudinal fold line in the wrapper. After filling, the part of the wrapper beyond the fold line is sealed over to complete the rod.
