A device for applying adhesive bands to packets, whereby an annular conveyor feeds the bands along a path having a first portion extending along a portion of the path along which the packets are supplied, a second portion extending between the output of the first portion and a loading station where the bands are loaded on to the conveyor, and a third portion extending between the loading station and the input of the first portion and past a gumming device; the conveyor being a suction conveyor having at least a first suction chamber wherein a selective vacuum is formed and extending along the first and second portions of the path along which the bands are fed, and a second suction chamber wherein a constant vacuum is maintained and extending along the third portion of the path along which the bands are fed. |
