Labeling apparatus and method cuts labels from a web of label material after adhesive is applied to the web of material. Under one embodiment heated knives are carried on a vacuum drum which cooperates with a roller functioning as an anvil to cut the web into labels of the appropriate length. A sensor reads a mark of the indicia side of the web and controls movement of the web to assure proper registration. Under a second embodiment, a rotatable drum having a plurality of vacuum plates cooperates with a die cutting roller to cut labels of the desired shape. The cut labels are retained on the vacuum applicator plates which then are extended radially as they rotate to a position to apply the label to a container.
