A labelling system configured to apply a label to a product container includes a conveyor having a movable track including an infeed station and an outfeed station opposite the infeed station. The labelling system also includes a spindle rotatably supported on the movable track configured to support the product container, an applicator arm configured to feed the label toward the conveyor when the movable track advances the spindle and the product container toward the applicator arm, an actuator configured to move between a retracted position and an extended position, and a roller rotatably coupled to an end of the actuator. The roller is configured to press a leading edge of the label against the product container when the actuator is in the extended position, and configured to rotate and follow along at least a portion of the product container and press the label against the portion of the product container.
