ABSTRACT:
Apparatus for making composite filter plugs for cigarettes or the like has a garniture which transports a web of cigarette paper or the like past a transfer conveyor which deposits on the web groups of aligned filter rod sections of two or more different types so that the sections are disposed end-to-end and form a continuous filler. Those portions of the web which are contacted by the sections are coated with a wet adhesive or a heat-activatable adhesive to insure that the sections cannot be shifted relative to the web, and the adhesive is heated or cooled in the region of the transfer conveyor to promote rapid setting. One marginal portion of the web is coated with wet adhesive or heat-activatable adhesive upstream or downstream of the transfer conveyor, and the web thereupon passes through a wrapping mechanism which drapes the web around the filler so that the one marginal portion adheres to the other marginal portion and the web constitutes the tubular wrapper of a filter rod which is severed at regular intervals to yield filter plugs each of which contains at least a portion of each type of section. The adhesive which is applied by the second paster is heated or cooled downstream of the wrapping mechanism.
