Vacuum drum, particularly for a roll-fed labelling machine, and vacuum drum pad

A vacuum drum adapted to receive a labelling material web, configured to be operatively coupled with means for cutting said labelling material web into portions, for applying an adhesive on said cut portions of labelling material and for transferring, downstream from said applying means, the glued portions to respective items to be labelled;

• the vacuum drum having a lateral surface comprising at least one section adapted to cooperate with said portions and delimited, at opposite angular ends, by respective front and back damping pads arranged and configured to receive and cooperate, in use, with the leading and trailing edges, respectively, of said portion;
• and
• said lateral surface section comprising one or more panels defining a quasi-cylindrical surface;
• characterised in that said front damping pad and said at least one panel comprise, at least in a superficial portion thereof, a material such that the adhesion of said adhesive to said labelling material is greater than the adhesion of said adhesive to said material, the cohesion of said adhesive being also greater than the adhesion of said adhesive to said material.
