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 (2) in a continuous wrapper (10) 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 (10a) of the wrapper and on the other side by a longitudinal fold line (10c) in the wrapper. After filling, the part (10b) of the wrapper beyond the fold line (10c) is sealed over to complete the rod. <IMAGE>
