Abstract: A method for applying adhesive on a wrapping band of a smoking article includes moving the band along a feed direction, the band has a longitudinal direction of extension, opposing first and second surfaces, a first plurality of portions having a first thickness and a second plurality of portions having a second thickness greater than the first thickness, the portions of the first and second pluralities being disposed alternately along the direction of extension. A nozzle having a delivery end, and the band are moved towards/away from each other between a first position, where the delivery end and the second surface are at a first distance which is less than or equal to the second thickness, and a second position, where the delivery end and the second surface are at a second distance greater than the second thickness. An adhesive is delivered on the first surface through the nozzle.

Abstract: A device for combining filter segments with cigarette rod segments includes a first feed device for feeding a succession of gummed connecting strips and a second feed device for feeding a succession of groups, each including at least one cigarette rod segment and one filter segment, abutted end to end. A combining conveyor receives the groups in a first receiving station and the succession of strips in a second receiving station downstream of the first receiving station so that each gummed connecting strip is applied in flag-like manner on a respective group to connect the cigarette rod segment to the filter segment. A rolling drum receives the group with strip and rolls the strip round the group. A compression device downstream of the second receiving station and upstream of the release station produces compression between each group and the respective strip.
