ABSTRACT:
Apparatus for joining at least two axially abutting rods of the cigarette industry comprises means for delivering the rods to a rolling drum, a rolling device mounted adjacent to the drum to roll the rods with respect to the drum, and means for applying a hot-melt adhesive to the rods to produce a bonding film which overlaps the adjacent ends of the rods and extends at least around a major part of the circumference of the rods.
The adhesive may be applied by a nozzle directly to the rods, or may be applied initially to the drum as a film which is then picked up by the rods.
