ABSTRACT:
A device for applying filters to cigarettes by means of adhesive connection bands of a type comprising a peripherally grooved conveyor roller which transfers to a position, referred to as rolling position, units comprising two axially aligned cigarettes with the interposition of a filter section. At the rolling position an element, referred to as counter-rolling element, defines in combination with said conveyor roller a passage at which said bands are rolled up about the units. By means of a cutting device cooperating with said conveyor roller, the bands are provided by a paper web fed from a reel.
After receiving adhesive on one face by a gluing device and before reaching the conveyor roller, said web skirts the surface of a heated rotating roller which causes the partial evaporation of the solvent in the adhesive.
