A method and apparatus are disclosed for applying labels to a rotating container on a rotating turret. The apparatus comprises a rotating turret with an array of rotating container bays that can hold containers arrayed about the periphery of the turret. The container bays are configured to rotate containers therein about their axes as the entire turret is rotated about its axis. A label application assembly is disposed adjacent the turret and includes an application roller that is movable by a servo drive radially toward and away from the turret. A label web passes over the application roller. In operation, the turret rotates to bring rotating containers toward the application roller. Before each container aligns with the application roller, the roller moves toward the turret to contact the container surface and begin application of a label. As the container moves into alignment with and past the roller, the roller is retracted and extended in such a way that it maintains contact with or profiles the surface of the container until the label is transferred completely to the container. The turret then speeds up to bring the next container into position for label application, thereby increasing throughput.
