ABSTRACT:
A cylindrical vacuum drum for carrying a label held to its surface by vacuum past an adhesive applying roll to a position where the label will touch a container and the container will be rolled along the drum surface to thereby apply the label about the container. The drum is formed of metal and is mounted for rotation about its vertical axis. The drum has a rubberlike covering thereover with at least two raised areas in the cover, which underlie the leading and trailing edge of a label that is at a greater radius than the rest of the surface. These are the areas which serve to press the label against the adhesive roll or solvent applying gravure roll. These areas have very slightly depressed zones forming slight steps just in advance thereof with a row of vacuum ports extending through the cover at the base of said steps to effectively hold the leading edge of the label down and allow the trailing edge to bend upwardly away from the outer surface of the drum. Additionally, replaceable insert strips are provided for the trailing edge of each raised pad that underlies the trailing edge of the labels so that this area which exhibits the most wear can be replaced rather than require replacing the entire drum.
